Motoblock Tselina MB-601. Review, characteristics, reviews

Walk-behind tractors (MG-tractors) are mobile compact devices equipped with special attachments for cultivating personal plots. A mini tractor is a complex unit consisting of several autonomous systems:

• engine;
• transmission;
• chassis;
• governance mechanisms;
• optional equipment.

Walk-behind tractors are equipped with gasoline or diesel engines with a liquid or air cooling system. Gasoline power units are divided into two- and four-stroke, diesel power units are only four-stroke.

The transmission of an MG tractor transmits rotating forces from the motor to the drive wheels of the unit and consists of the following units:

• clutch;
• gearboxes;
• differential and gearbox (heavy models only).

In other words, a walk-behind tractor is the same car, equipped with an internal combustion engine, including all the necessary systems for its successful operation. Therefore, for its operation the same classes of oils and the same requirements are provided as for large transport units.

What kind of oil is poured?

Many people are interested in what kind of oil to pour into the gearbox of a walk-behind tractor? To answer this question, you need to take into account several factors, the main one of which is the manufacturer's recommendation regarding the type of oil.

You also need to be guided by price, without buying very cheap liquids, because they are unlikely to be of adequate quality.

In general, oils can be of various types:

• SAE. These types of oils cope very well with sudden temperature changes, so they can be used all year round.
• The selection process is as follows: you need to look at the number in front of the letter W - a lower value will indicate that the oil is very well adapted to low temperatures (the smallest is 0W). If the letter W is not on the label, then this oil is suitable for the summer period.
• API. In this case, the letters in the marking will indicate the type of engine - gasoline or diesel. Accordingly, a certain letter will indicate that the oil is suitable for gasoline units, and another – for diesel units.
• The numbers will indicate the type of engine, i.e. number 4 means the oil should be used for a 4-stroke engine, etc. The EC value is the degree of energy conservation, i.e. The higher the value, the better the quality of the oil.
• ASEA. The highest number in the labeling will indicate that the oil can function in very difficult conditions.
• GOST 17479, 1-85. These indicators characterize the degree of viscosity of the oil. As a rule, alphabetic and numerical values ​​are written after this parameter, and their absence indicates that the oil is universal.

Choice

You can simply get lost in the widest range of products from a large and well-known Chinese manufacturer. If you go shopping for the right unit, you should keep in mind the following important features that will prevent you from purchasing the wrong model.

The main thing you will need to pay attention to is the power of the selected engine. As mentioned above, for a small area where you will not use the walk-behind tractor too often, it makes no sense to buy an expensive option

A cheap, low-power unit is quite suitable here. If we are talking about a large processing area and fairly frequent use, then it is advisable to select more powerful and heavier units - only they can cope with serious loads. Take a closer look at the motor mounts. They must fit the mounts available on your walk-behind tractor. Of course, they may differ, but then you will have to “adjust” them to each other yourself, which is undesirable. If you have any difficulties in this matter, it is better to seek help from a sales consultant.

The weight and size of the engine must correspond to the walk-behind tractor that you have in your arsenal. Such equipment must be performed with high quality. Engine assembly must be perfect

Carefully inspect it before purchasing, pay attention to all the details of the design. You should buy an engine for a walk-behind tractor (or other suitable motorized equipment) from Lifan in a trusted specialized store that sells products of a similar category. You should not purchase such units in markets or small trading modules

This way, you risk stumbling upon a fake or used product of low quality.

How to fill oil into a walk-behind tractor gearbox

Before pouring new oil into the gearbox, you need to drain the old fluid. This is exactly how the oil is changed in the gearbox of the Salyut walk-behind tractor, a video of which can be found on the Internet, as well as other models of walk-behind tractors.

The algorithm of actions will be as follows:

• The walk-behind tractor needs to be installed on some hill so that the oil can be easily drained from the gearbox.
• There are two plugs on the gearbox - a drain plug, which is located at the bottom of the gearbox, and a plug that closes the oil filling hole. First, unscrew the filler plug, which is located on top of the walk-behind tractor body (at the gearbox).
• We take a sufficiently capacious container (an old bottle of transmission oil will do), and then place it under the gearbox drain plug.
• Carefully unscrew the drain plug, after which the oil will begin to flow into our container. After waiting until the oil has completely drained, screw the drain plug back in. Then tighten it with a spanner of a suitable diameter until it stops.

• Insert the funnel into the filling hole. Then we take the appropriate gear oil to fill the gearbox.
• Having filled the reducer to the optimal level, screw the plug back. This plug is equipped with a special dipstick, and its length is approximately 10 cm. After we have filled in the oil, we need to check its level. To do this, we tighten this plug-dipstick, after which we unscrew it again and check it.
• If the oil is at the tip of this dipstick, then there is no need to add any more.

As a rule, the oil change procedure must be performed every 100 hours of operation of the walk-behind tractor. In some cases, this procedure must be performed every 50 hours.

In other words, the frequency of oil changes depends on the model of the walk-behind tractor, so all the necessary information is in the accompanying documentation for the walk-behind tractor.

Changing the Oil in the Gearbox of the Plowman Motoblock

Many new owners of walk-behind tractors are interested in issues related to the use of oils for agricultural machinery. It is necessary to consider which compositions are suitable for lubricating certain devices of the walk-behind tractor, and how to use them for smooth operation and extending the life of the unit. The working life of the motor of an agricultural implement depends not only on the properties of its devices and assembly, but also on how well

How much to fill?

Another important point is the amount of oil needed. Before answering the question - how much?

oil must be poured into the gearbox of a walk-behind tractor, for example Crosser, Viking, Forza, Sadko, Don, Huter, Profi, Plowman, Champion, Carver, you must first check the oil level in the gearbox. To do this, you need to perform certain actions:

• It is necessary to place the walk-behind tractor on a flat surface so that its wings are strictly parallel to this surface.
• We take a wire or rod about 70 cm long, which will act as an oil dipstick.
• We bend the improvised probe into an arc.
• We insert the resulting dipstick into the filler hole to the very end, i.e. all the way. After that we pull it back out.

If the wire is 30 cm deep in oil, then this is the optimal indicator, i.e. no need to add oil. If it is a little less, then it is necessary to top up within these values.

If the gearbox is completely dry, then you will need at least two liters of gear oil.

Changing the oil in a walk-behind tractor: what and how much to fill in the gearbox

Few people can be surprised by the presence of a walk-behind tractor in a private household, because this technical device has been known since Soviet times. Thanks to him, it became possible to quickly and efficiently cultivate the soil, which previously took quite a long time and also took a lot of effort.

However, in order for your walk-behind tractor, as they say, to serve you faithfully, regularly plowing the ground and performing its other functions, you need to operate it correctly.

In particular, you need to know how many

pour oil into the gearbox of the walk-behind tractor so that it works in optimal mode, and its parts do not wear out due to the lack of necessary lubrication.

In principle, all the necessary information, as a rule, is indicated in the operating instructions for a specific walk-behind tractor model, where the brands and grades of recommended oils are directly indicated.

However, there are cases when a walk-behind tractor is purchased by hand or in another way, but the point is that such walk-behind tractors are supplied, basically, without any instructions.

A person may be at a loss, not knowing what kind of oil is poured into the gearbox of a walk-behind tractor, so it will be useful for him to know about its main types, as well as how to fill it into a walk-behind tractor.

Advantages and disadvantages of Lifan walk-behind tractors

The Lifan walk-behind tractor, according to user reviews, is a reliable and powerful piece of equipment that can cultivate both small and large areas of land. Ease of use allows even novice users and retirees to work with the walk-behind tractor. The price-quality ratio, according to people's reviews, meets expectations.

Among the shortcomings, users highlight the need to quickly replace the original spark plug, and the strict adherence to the rules of use and technical control. Otherwise, the Lifan walk-behind tractor fully complies with the stated characteristics and, with proper maintenance, works properly for a long time.

Device

Gearbox

is a special device included in the design of any walk-behind tractor. It is this part that is responsible for converting and transmitting torque that is generated from mechanical transmissions. In fact, the gearbox powers the walk-behind tractor, making it work.

The service life of the entire walk-behind tractor, as well as its normal functioning, will depend on its quality, as well as on the correct lubrication of its components.

For more details about the gearbox, see

Depending on the model of the walk-behind tractor, be it Cayman, Patriot Ural, Patriot, Texas, Foreman or some other, the gearboxes may differ from each other in some design features. Conventionally, gearboxes can be divided into several types:

• Angular reducers. Such units are quite effective and allow you to couple the engine and transmission.

• Gear reducers. In this case, the gearbox transmission acts as a kind of intermediary between the engine and the wheelbase of the walk-behind tractor.
• Reduction gearboxes. These units achieve an increase in power indicators by reducing the total number of revolutions. Such gearboxes are most preferable because their design includes an air cooling system, which allows them to operate at maximum loads.
• Reverse gearboxes. The main advantage of such gearboxes is the ability to reverse the walk-behind tractor. However, units equipped with this type of gearbox do not show high performance indicators and speeds.

Regardless of which gearbox is used in the design of the walk-behind tractor, they all consist of almost the same components:

• shaft;
• gear housing;
• flange and its fastening;
• pulley with V-belt drive (or chain);
• ball bearing;
• stars;
• drain plug;
• steel washer and nut;
• input shaft

These components traditionally form the gearbox itself. Their performance and service life will depend on how well they are lubricated.

Otherwise, if there is insufficient lubrication, the parts will wear out greatly, because they come into contact with each other during operation, and the resulting friction negatively affects their surface.

Periodically changing the oil in the gearbox is extremely important, not only because it is recommended by the manufacturer, but also for a number of other reasons. In particular, during the operation of the walk-behind tractor, foreign metal particles are formed in the oil located in the gearbox.

They arise from friction and contact between the components of the walk-behind tractor, which gradually crumble, and all this metal chips end up in the oil. Thus, the oil begins to thicken, which leads to unstable operation of the walk-behind tractor, and subsequently to failure of the gearbox.

That is why timely changing the oil in the gearbox is a necessary preventive measure to avoid repairs in the future.

Indeed, it is much more logical to spend an amount of up to one thousand rubles on the purchase of gear oil than to spend much more money on expensive repairs or a complete replacement of the gearbox.

Types of oils

Oils differ by type (mineral, semi-synthetic, synthetic), areas of application (motor, transmission), and seasons (summer, winter). Gearboxes use transmission oils with various additives.

Classification of gear oils by area of ​​application:

• GL-1 are mineral oils without additives or extreme pressure components. Designed for use at low speeds and loads. Used in spur, worm and spiral bevel gears.
• GL-2 - “mineral water” with increased requirements for anti-friction properties, that is, resistance to abrasion. They are used in worm gears, the operation of which is accompanied by constant friction of parts against each other. May contain special anti-friction additives.
• GL-3 is a lubricant with high anti-wear and extreme pressure properties, that is, they prevent adhesion of contacting surfaces. Designed for moderate speeds and loads. Used in spiral bevel gears.
• GL-4 - oils with high-quality extreme pressure additives. Designed for high speed operation in combination with low torque and vice versa. Used in hypoid transmissions of cars and trucks.
• GL-5 and GL-6 contain an extreme pressure additive containing sulfur and phosphorus. Designed to operate at high speeds at low torques, as well as shock loads on gear teeth. Oils of the GL-6 group, in addition, are designed to operate gears with vertical displacement along the axes. Used in hypoid transmissions of cars.

Changing the oil will not take much time

Attachments

Tselina walk-behind tractors work with a large number of Perm-made attachments. again, the equipment can be used with equipment from other brands, but here you need to carefully examine the mounting points. The most popular types of attachments:

• wheel hub extensions;
• adapters and various couplings;
• Tselina milling cutter is the main equipment used with this technique. What distinguishes it from analogues is the high quality of work. When cultivating the soil at low speeds, the roots of the weeds remain on the cutters and are not cut. Due to this, most of the rhizomes can be pulled out of the ground. The manufacturer offers several types of Celina cutters;
• potato digger;
• plow;
• cart.

Almost no active equipment is produced under the Tselina brand. The only available models are the SP-70 and SP-56 snow blowers.

Features of Tselina walk-behind tractors:

• wide wheels with a diameter of 180 mm, increasing the maneuverability of the equipment;
• rotating steering column with the ability to adjust in the horizontal and vertical planes;
• wide range of models;
• reinforced gearbox;
• upgraded gear shift lever;
• possibility of using attachments from other domestic manufacturers;
• significant engine life - more than 3000 hours;
• wide mudguards and fenders provide additional protection for equipment;
• many service points for walk-behind tractors, which are located not only in Perm, but also in other Russian cities;
• possibility of equipping with a headlight, battery and electric start.

Oil change procedure

Replacement occurs as follows:

• Start and warm up the engine.
• Place the walk-behind tractor level on stands or a surface raised above the ground.
• Place an empty container for used oil under the drain hole of the tank and open the plug.
• After the oil has completely drained, close the drain hole tightly.
• Pour fresh lubricant into the upper hole, checking the level with a dipstick. How much oil to pour into the walk-behind tractor gearbox depends on its volume. Typically a dry gearbox requires about 2 liters. The exact figure is indicated in the operating instructions.
• Wipe both holes to remove any remaining grease.

In what cases should you change the oil:

• if the gearbox has been repaired;
• if the oil level is extremely low;
• if a new type of lubricant is used;
• if it is time for replacement according to the operating instructions.

This is a fairly simple operation for which you do not need to go to a service center. High-quality gear lubricant is not cheap, but you can save on the work of replacing it.

The exact frequency of changing grease and other technical fluids is indicated in the instructions. On most models of walk-behind tractors, this operation is carried out after the first 25 hours of operation (on new equipment or after replacing the gearbox), then every 250 hours of operation, that is, on average once a month for daily work or once a season for occasional use. Work to replace the lubricant should be carried out immediately after work, and the level should be measured before it begins.

Operating instructions for Ugra NMB-1N17

Ugra NMB-1N17 goes on sale with instructions for use. According to this document, it is unacceptable to load the walk-behind tractor at full power in first gear without attached attachments. Otherwise, the speed limit of 3 km/h in this gear will be exceeded and the device may fail.

Speed ​​optimization

In the first days of operation, it is recommended to operate the engine at 2/3 power; it is allowed to operate at full speed for no more than 30 minutes. After 30 hours of operation, the break-in period can be considered completed, and the walk-behind tractor can be loaded at 100%.

The oil change on the Ugra NMB-1N17 walk-behind tractor is performed after break-in, that is, 30 hours of operation after the first start. During scheduled maintenance, the oil level is checked and topped up to normal. The oil is changed after 100 hours, then the pattern is repeated.

Motoblock gearbox design

Gearbox

- one of the most important components of a walk-behind tractor. It is available on absolutely all models; without it, the equipment will not work. The function of the gearbox is the uninterrupted transmission of torque from the engine to the wheels through a V-belt drive. In addition, it provides a change in the speed and direction of movement of the agricultural unit. Simply put, it provides movement and control of equipment.

The gearbox consists of a system of shafts and sprockets connected by a chain. The shafts receive rotation and are transmitted using a chain. The input shaft is equipped with a lever and a fork that switches the mechanism. A bolt-on plastic housing protects the parts from dirt and dust.

Walk-behind tractors are indispensable helpers on the farm.

All parts are made of metal and require lubrication. If there is a lack of lubrication, the load on the contacting parts increases sharply, which can lead to their rapid destruction. Timely replacement of oil in the gearbox will ensure their serviceability and uninterrupted operation of the mechanism as a whole.

For diesel engines

Diesel fuel contains a lot of sulfur and produces soot when burned. The lubricant for this type of motor must provide cleaning properties and be resistant to oxidation. These properties are provided by special diesel additives. In addition, the oil in engines of this type needs to be changed more often, as it quickly becomes saturated with sulfur deposits, soot and oxidation products.

For gasoline engines

Transmission oil should not be confused with motor oil. When filling the engine with lubricant, the type of fuel must be taken into account. The base for gasoline and diesel oils is often the same; the differences lie in additives - special components that provide the oil with the desired properties.

Gasoline engines run on relatively light, low-sulfur fuel and reach relatively high maximum speeds. This means that gasoline oils must protect and lubricate friction parts at high speeds. A set of additives is selected in accordance with these requirements.

What kind of oil to fill in the gearbox of a walk-behind tractor?

Summer residents, entrepreneurs, farmers - everyone is interested in gardening equipment working for a long time and without interruption. Proper maintenance and operation of a walk-behind tractor or cultivator helps extend the life of the equipment and increase its productivity. One of the most important structural elements of a walk-behind tractor is the gearbox, and it depends on what kind of oil is poured into the gearbox

walk-behind tractor, its performance depends. Each owner should know what kind of lubricant should be used in the gearbox and what is the frequency of its replacement.

What kind of oil should be poured into the gearbox?

When it comes to the question of what kind of oil to pour into the gearbox of a walk-behind tractor, the most reliable option is to rely on the manufacturer’s recommendations. They are outlined in the instruction manual, and if it is lost, the text can be easily found on the Internet. In general, any transmission oil is used to lubricate the gearbox. It is not advisable to mix oils to avoid conflict between additives. In rare cases, when mixed, substances can turn the entire lubricant into an emulsion, which can lead to gearbox failure or, at a minimum, a thorough rinsing of it. Therefore, before adding new oil, you should check for the presence of old oil.

For gasoline engines

For walk-behind tractors running on gasoline, it is recommended to pour

the following types of liquids into oil containers:

• SA - for work with low loads;
• SB - for work with medium mechanical load;
• SC - used in engines without PCV valves;
• SD - works in engines with PCV;
• SE - lubricant for use in engines manufactured since 1980;
• SF is a higher quality analogue of the previous oil;
• SH - used in many engine systems.

Category SB has good anti-corrosion properties. The product efficiently lubricates cylinder walls and bearings. SF reduces the amount of oil deposits in 4-stroke and two-stroke engines.

Taking it apart is not a problem

Regarding the flywheel fixation, it is carried out in such a way that the fan blades were not damaged during dismantling. Unscrew the nut that secures it and proceed to the next step. Namely: pressing the flywheel using a universal three-fingered puller. If you are disassembling the engine to understand what caused it to start incorrectly or reduce its power, then you should check whether the keyway is damaged. In this case, the flywheel will either be shifted or the ignition timing will change. The latter will be clear from the displacement of the magnetic mark. The ignition coil must be removed, as well as the lighting winding (if the engine has one).

When you unscrew the valve cover fasteners, take care of the bolts that secure the cylinder head and remove it itself. Turn the head over so that the chamber is facing up, then fill it with kerosene. This is necessary to check the head for valve tightness. If after a minute kerosene does not appear in one of the channels, then the valves are sufficiently sealed. Otherwise, the valves should be ground to the seats. For this, abrasive paste is used.

When you unscrew the bolts from the rear cover, you will be able to get to the crankcase and remove the camshaft from it. As a result, space in the crankcase will be freed up and it will be possible to unscrew the bolts from the lower connecting rod cover. Before putting everything back together, the rubbing parts must be lubricated with engine oil, and the insides of the combustion chamber must be cleaned of carbon deposits.

What kind of oil to fill in a MTZ walk-behind tractor with a Honda engine

MTZ walk-behind tractors have established themselves as high-quality agricultural equipment; in combination with the world-famous Honda engine, they have excellent performance characteristics.

For proper operation of the entire device, it is necessary to carry out timely technical inspection, including checking the oil level. What kind of oil should I use? Belorus 08H-09H walk-behind tractors with Honda GX 240, 270, 340 and 390 engines are suitable for oil classified no lower than SG and SF; all-season oil SAE 10W-30 is recommended, but under specific temperature conditions it is necessary to select a special oil.

Engine for walk-behind tractor Neva MB-1

By using technology in agriculture, you can significantly reduce energy and time costs.
The most popular and functional modification remains the MB-1. The production of the engine dates back to 1984, but even today the engine does not lose its leadership position. It can be used to plow, cultivate, loosen the soil, cultivate rows, mow the lawn, remove snow and perform many other tasks.

The engine is equipped with a gearbox with high traction capability. This technological move allowed us to achieve an excellent level of performance with minimal power consumption.

The left and right wheels are independently decoupled, allowing separate torque cut-off. This increases the maneuverability of the walk-behind tractor.

What kind of oil to pour into the Lifan walk-behind tractor

Choosing the right oil is the key to proper engine operation. In the instructions that come with the walk-behind tractor, the manufacturer always notes what kind of oil is needed for this engine.

The Lifan walk-behind tractor needs high-quality oil. For four-stroke engines, it is prohibited to use oil suitable for two-stroke engines. It should also be without additives.

For Lifan walk-behind tractor with 6.5 hp engine. SAE 5W-30 oil is required with the gearbox. For most models with engines of different power (5.5 hp - 13 hp), SAE - 30 year old or all-season SAE - 10W-30 oil is suitable.

By viscosity

Viscosity is determined according to SAE J300 standard. For mechanisms it depends on the following characteristics:

• unit design;
• features of work;
• age of the mechanism;
• ambient air temperature.

Motor oils are divided into winter and summer. Winter ones are designated with the letter W. Low-viscosity winter grades are often used with SAE designations 0W, 25W, as well as intermediate values ​​20W, 5W, 15W and 10W. Compositions for use in summer do not have letters in their names. They are distinguished by high viscosity and are designated SAE 20, 60, SAE 30 or 40. When using summer brands in winter, problems arise associated with starting the unit. Winter varieties are not capable of providing high-quality lubrication in the summer.

Scientists have developed all-season compositions that are used for pouring into walk-behind tractors in summer and winter. Their designations are 5W-40, 10W30.

For diesel engines

With the recommended motor oil, owners increase the resource of the unit and reduce diesel fuel consumption for a diesel walk-behind tractor. The instructions for a walk-behind tractor with a diesel engine indicate the following categories of lubricants:

• SA - for working with low loads;
• SV - for working with high-sulfur fuel;
• CC - for a non-turbocharged engine operating under increased loads.

Category CA reduces the amount of carbon deposits in the cylinders, but reduces the quality of the lubricant. Any lubricant is poured in the required volume. Reducing or increasing it leads to jamming of the motor.

By composition

In addition to seasonal characteristics, lubricants are divided into types based on composition:

• mineral;
• synthetic;
• semi-synthetic.

An air-cooled engine heats up quickly during operation. Motor oil reduces its temperature. The wrong category causes a breakdown in the motor. It is not recommended to use synthetic oil in mixture with mineral oil.

Lifan engine

The Lifan company installs several types of engines of different power and modifications on its walk-behind tractors. The most popular diesel walk-behind tractor is the 186FD. However, such a configuration from the manufacturer costs an order of magnitude more, which means that most consumers still choose familiar models with a 4-stroke gasoline engine.

In order to avoid malfunctions of the Lifan engine, you need to carefully monitor its condition and carry out timely maintenance. Let's look at the main parts of the power unit and possible malfunctions of the Lifan engine, as well as ways to eliminate them.

Main engine parts

In order to understand where the breakdown occurred and how to fix it, you should know what the Lifan engine consists of:

• Fuel tank.
• Gearbox.
• Engine Lifan.
• Muffler.
• Air filter.

These are the main parts of the Lifan engine, which are responsible for the smooth operation of the power unit. Let's look at the most common starting problems and engine features during repair.

Fuel supply problems

This is the most common problem that novice walk-behind tractor users may encounter. Most often this is not a problem at all.

The way to fix the problem is to fill the tank and open the valve.

If these measures do not help, you need to clean the air valve or fuel tap; it may be clogged. If these measures do not bring results, you may have filled in with low-quality fuel that should be replaced. If the cause of poor fuel supply is a broken needle valve or carburetor float, repair of these engine parts is necessary.

Stopping the engine

If the Lifan walk-behind tractor suddenly stalls during operation or startup, this may be due to one of three main reasons, namely:

• Malfunction of the ignition system - the ignition timing needs to be adjusted.
• Malfunction in the fuel supply system - identify the cause and eliminate it.
• Compression failure - replace worn parts, adjust clearance or repair valve.

According to user reviews, these are the most common faults found in the Lifan walk-behind tractor. However, engine repair is not difficult and can be done independently with a basic set of tools.

Classification of oil grades

To increase the service life of a gasoline or diesel engine, you need to make the right choice of engine oil. Failure to replace it in a timely manner reduces the service life of the engine. How to choose it, in what quantity, how to pour it into the walk-behind tractor - we’ll talk about this in more detail.

Each mini-tractor or walk-behind tractor includes instructions and a product data sheet. In the instructions, the manufacturer lists suitable types of fuel and lubricants that can extend the life of the equipment. Engine oil performs the following functions:

• cooling;
• lubricants;
• seals;
• cleaning.

During air cooling, the lubricant settles on the walls of the hot cylinder. These deposits contaminate engine parts and complicate lubrication processes. Therefore, the lubricant contains antioxidant additives. They clean the cylinder walls from carbon deposits and extend the service life of the walk-behind tractor. Different climate zones require the use of different oily liquids. They differ in viscosity, composition and purpose.

By purpose

If there is a need to replace lubricating fluids, each manufacturing company recommends filling in its own brand. For agricultural machines, Honda uses all-season grades 10W-30 of the SF category. Subaru in its recommendations indicates 10W-30 for operation in moderate climates, and 5W-30 in cold regions. Oil quality category - SE.

Lifan products require summer grade SAE-30, and SAE 10W-30 for winter conditions. There are no conditions for quality category. Motoblocks of the Kaluga Engine company are filled with an all-season composition 10W-30 or 15W-30 of SF or SH quality.

In the engine

The primary oil change in the internal combustion engine occurs after 28-32 hours of operation. The next replacement can be made no more than 2 times a year - in summer and winter, even if the unit has been standing for some time without operation. To begin the replacement process itself, you need to prepare special attributes - a funnel and a container for draining the waste liquid.

At the bottom of the engine there is a hole with a cap through which old oil can be drained. A drain container is placed in the same place, the locking cap is unscrewed, and the waste liquid is drained. It is necessary to wait some time for the residue to completely drain from the engine system. Then the plug is screwed into place and fresh oil .

Its quantity should be identical to the drained amount. If it is not possible to take measurements, it is better to look at the technical data sheet of the unit, where the required number in grams is indicated. After new oil has been poured into the engine, it is necessary to check its level. To do this, just use a special probe.

It is worth noting that in some engines that are sensitive to oil fluids, for example, Subaru or Honda, it is assumed that they use oils of a certain class, that is, SE and higher, but not lower than the SG class.

This instruction is general for both two-stroke and four-stroke models. More specific information on how to replace the oil fluid in a walk-behind tractor is best considered in the instructions for a specific unit.

Lifan 168

One of the most widely used engines.
Lifan 168. It has an engine capacity of 196 cubic centimeters and runs on gasoline. Power. 7 horsepower, air cooled, so they can only run for a short time. To ensure the service life of the Lifan engine, after installing the Chinese engine, it is necessary to constantly fill in fresh oil and carry out maintenance.

Installing the motor is simple and does not require modification of the frame mount.

Fluid replacement work is carried out as follows:

B.&S I/C

Motor B can also be installed.&S I/C, related to modern models and popular in everyday life. They are often used on cascade blocks.

This is due to the following engine features:

Vanguard ov

The imported Vanguard OHV engine is also one of the powerful engines that can be installed on the walk-behind tractor of this manufacturer and can perform all the necessary tasks. This engine has a power of 7 horsepower.

One refill is enough to work without a break for 4-5 hours.

Subaru EX17

You can install the Subaru EX17 engine, which is popular among owners of Cascade walk-behind tractors. It turned out great. It has a special camshaft design inside and a large shaft diameter to increase engine power and efficiency.

As you can see, at the moment there are quite a few motors that can be installed on the Cascade motor block. Choosing the right model depends not only on its functionality, but also on the financial capabilities of the owner.

It is recommended to purchase a motor based on the specific use of the machine to ensure longevity of the machine. Therefore, before purchasing, you need to understand the characteristics of the engine, consult with specialists and buy the best model.

It is also worth paying attention to the configuration, build quality and other points that are familiar to any car enthusiast. If you don't have the skills, you should always seek professional help. The engine must meet all requirements, which will allow it to operate efficiently and increase its service life

The engine must meet all requirements, which will allow it to operate efficiently and increase its service life.

Main problems of motors

Among the main failures of Cascade walk-behind tractors:

The reasons for such malfunctions can be very different. from low-quality fuel to lit candles. Low battery may also be the cause. In this case, charge the battery and clean the fuel line or spark plug and replace it completely if necessary.

Another malfunction may be loss of the engine. The main reason in this case is a clogged carburetor or filter, which prevents the required amount of fuel from entering the combustion chamber. In this case, it is recommended to clean the system, since a return is possible when the engine starts.

Experts recommend periodically servicing this equipment to avoid such problems.

All of the above failures are quite rare, and if necessary, you can fix them yourself, no special knowledge is required. If you have problems with maintenance or repair, you can consult a specialist or receive instructions on how to use the network.

Attachments

To increase the functionality of the Cascade walk-behind tractor, the manufacturer installs mounts on it, with which you can perform various operations.

Among the most common pendants:

How to change?

Anyone can replace the lubricant in a walk-behind tractor, but if there is any doubt, it is better to contact a highly qualified specialist. The procedure for updating with oil fluid in any model of walk-behind tractor is no different from each other, be it an Enifield Titan MK1000 or any other motor from the Nikkey line.

First of all, you should remember that the oil is changed only when the engine is hot, that is, the system must first operate for at least 30 minutes. This rule applies not only to four-stroke engines, but also to two-stroke engines.

Thanks to the above nuance, the warm waste mixture easily flows into the container placed below. Once the used oil is completely gone, you can begin the replacement process.

First you need to unscrew the breather plug, drain the remaining used oil and, if necessary, change the additional oil and air filter. Then you need to fill in fresh fluid and return the plug to its place. pour

New oil should be used carefully so that it does not get on other parts of the system, otherwise an unpleasant odor will occur.

Engine Maintenance

During operation, no significant problems should arise in the case of a fully functional new engine, but it is better to test it at maximum power within the warranty period. Engine maintenance is carried out by the owner himself, although with Lifan engines for walk-behind tractors there should not be any problems with this.

If problems do arise, you need to perform a number of simple procedures, after which the engine will work again “like new”:

• Replace spark plugs.
• Change the oil.
• Check the integrity of all connections.

No more adjustments are required, since the ignition in such engines is electronic. After completing the above steps, you can try to start the engine.

How to check the level?

Checking the oil level is carried out using standard technology to which every person is accustomed. To do this, the walk-behind tractor has a special probe that goes deep into the unit. Having taken it out of the hole, at the tip of the dipstick you can see a limiting strip, the level of which is equal to the oil level. If there is not enough liquid, it must be added. On the other hand, this nuance forces you to check the entire system, since a low level of lubricant indicates that it is leaking somewhere.

In addition to the standard dipstick, some models of walk-behind tractors contain special sensors that automatically show the amount of lubricant present. Even during the process of replacing the oil fluid, it can be used to determine how much the size of the lubricant composition has increased or its deficiency.

Specifications

The machine meets all the requirements for modern technology in terms of environmental friendliness and noise level. The noise emitted by the device falls within the range of no more than 92 dBA, which is why when working with this equipment on the site, even early in the morning, you will not disturb your neighbors.

Construction of the Tselina walk-behind tractor

Characteristics of the Tselina MB-601 walk-behind tractor:

• Recommended temperature range for use of the walk-behind tractor: all seasons at air temperatures from minus 5 to plus 35 degrees.
• The total weight of the device is 100 kg.
• Overall dimensions: length 1470 mm, height 1000 mm, width 580 mm.
• The track size is 35 cm.
• Ground clearance is 14 cm, turning radius is 110 cm, maximum speed is 9 km/h.
• Cultivation strip width: adjustable from 72 cm to 113 cm.
• The maximum angle of the inclined surface is 15 degrees.
• The walk-behind tractor can be used in all seasons, with the exception of severe frost.
• To fill the tank, use purified AI-92 gasoline.

Which one is better to choose?

As mentioned earlier, there are several types of oils for walk-behind tractors. It is necessary to use the liquid recommended by the manufacturer of the unit - to do this, just carefully study the labeling of the device and read the instructions.

In addition, each individual type of oil is divided according to its chemical composition into several types. In most cases, manufacturers try to manufacture units with the ability to use the most common types of oils - synthetic, mineral, and semi-synthetics, for example, Mannol Molibden Benzin 10W40 or SAE 10W-30.

It is worth noting that this lubricant contains a friction modifier, which creates a durable film on the inner surface of the parts. This significantly reduces the wear rate of the walk-behind tractor.

Another marking that should not be forgotten is the designation of the operating properties of oils. It also has several varieties. For example, category C is used for 4-stroke diesel engines, and category S is used for gasoline engines.

From these data a certain conclusion can be drawn. Considering the engine types, a high level of demand is directed towards all-season oils labeled 5W30 and 5W40. Among anti-corrosion oils, 10W30 and 10W40 are popular.

At temperatures above 45 degrees, oils marked 15W40, 20W40 should be used. For winter cold, it is necessary to use oil fluid 0W30, 0W40.

Purpose

When purchasing a new walk-behind tractor, the kit must include accompanying documents, which contain special sections with recommendations for proper care and operation. The names of oils ideally suited to the unit are also indicated there.

First of all, you should understand the basic functions of oil fluids. Liquids perform the following actions:

• system cooling;
• obtaining a lubrication effect;
• cleaning the inside of the engine;
• compaction

During operation of the walk-behind tractor in an air-cooled engine, the oil liquid begins to burn, and accordingly, burnt particles remain on the cylinder. This is why smoky exhaust is formed. In addition, tar deposits are the strongest pollutant for the remaining parts of the walk-behind tractor, making lubrication of parts more difficult.

It is preferable to fill the oil for a walk-behind tractor together with antioxidant liquids, which are a cleaning agent for the inside of the unit.

To choose the right oil fluid, you should remember that each individual composition is intended for a specific season and climatic temperature.

In simple words, you cannot use summer oil

• The summer variety of oil liquid is used exclusively in the warm season. Has a high level of viscosity. There is no letter designation.
• Winter varieties of oils are used during cold periods. They have a low viscosity level. The letter designation is W, which means “winter” in English. This variety includes oils with the SAE 0W, 5W, 10W, 15W, 20W, 25W index.
• A variety of all-season oils are becoming more popular in the modern world. Their versatility allows you to fill the engine with liquid at any time of the year. It is these lubricants that have a special index in the general classification: 5W-30, 10W-40.

In addition to seasonality, oils are divided by composition. They are:

• mineral;
• synthetic;
• semi-synthetic.

In addition, all oils differ in the performance requirements of a 2-stroke and 4-stroke engine.

Walk-behind tractors usually use a 4-stroke air-cooled system and, accordingly, oil

must be 4 stroke.
In the winter season, the most preferable option is transmission motor oil
, for example, 0W40.

The price of the issue is, of course, high, but the response of the unit is its long service life.

In the gearbox

The gearbox is the most important part, because it is responsible for converting and transmitting torque from the gearbox. Careful care and quality oil

, used for the device, significantly extends its service life.

To replace the oil composition in the gearbox, it is necessary to perform a number of manipulations.

• The walk-behind tractor must be placed on some hill - preferably in a pit.
• Then the hole for disposal of used oil is unscrewed. The locking plug is usually located on the transmission itself.
• After this, a prepared container is placed to drain the damaged lubricant.
• After complete drainage, the hole must be tightly closed.
• When these manipulations are carried out, clean oil must be poured into the gearbox.
• Then you need to tighten the hole plug.

It is worth noting that in some gearbox models, for example, in the Efco line, there are through bolts that determine the amount of oil, which can be used as a guide when filling the fluid. In other models there is a special dipstick, by which you can see the total volume of the filled oil composition.

The initial oil change is performed after the break-in time has passed. For example, the Energoprom MB-800 model has a break-in time of 10-15 hours, and the Plowman TSR-820 unit has a break-in time of 8 hours. But the Oka line of walk-behind tractors was designed with a 30-hour break-in period. Subsequently, it is enough to drain and fill in new oil every 100-200 hours of full-time operation.

Criterias of choice

When choosing an engine for a walk-behind tractor, you should pay attention to several characteristics. First you need to decide on the type of engine

Walk-behind tractors use both gasoline and diesel units. The table shows their advantages:

The second criterion when choosing a Chinese engine is power:

• On a light walk-behind tractor it will be enough to install a device with a power of up to 4 liters. With.;
• medium ones require an engine with 4–7 liters. With.;
• for heavy walk-behind tractors, a 7 hp unit is required. With. and more.

You also need to pay attention to the following characteristics:

• Crankshaft output. The most common ones are with a key, and those often used are with a splined exit. Less commonly used is a conical shaft overhang.
• Oil level sensor. This will prevent damage to the device.
• The presence of an electric starter will make it much easier to start the engine when it comes to gasoline units. Diesel engines are more suitable for manual starting.
• Air filter. It comes with an oil bath and double cleaning.
• Motor resource. Models where this criterion reaches 3000 operating hours or more are recommended.

Can I use car oil?

It is strictly forbidden to use machine oil

in walk-behind tractors. Unlike a car engine, a walk-behind tractor has certain lubrication principles and corresponding operating temperature conditions. In addition, walk-behind tractor engines have certain features. These include the material of construction from which it is made, as well as the degree of forcing. In many cases, these nuances are incompatible with the characteristics of automobile oils.
