Affordable, reliable, multifunctional. AGAT (Salyut 5)

Russian-made walk-behind tractors “Agat”, due to their ease of operation and low maintenance, are in demand among both summer residents and professional gardeners and farmers. They are popular not only in Russia, but also abroad, and show excellent performance with the ability to install additional attachments.

The instructions for Agat walk-behind tractors are taken from the description of time-tested units of small agricultural machinery "Salut" with adaptation to modern production conditions. The main difference in the documentation lies in the features of the power units. Today, most Agat walk-behind tractors run on Chinese Lifan engines, and this was one of the reasons for the separation of the two productions.

What kind of oil to pour into the engine of an agate walk-behind tractor

The most correct recommendation for selecting oil will be the recommendation of the engine manufacturer for the walk-behind tractor.
Therefore, we will familiarize ourselves with the operating instructions of the main manufacturers of engines for walk-behind tractors and provide excerpts from the instructions. The choice of motor oil, like any other type of oil, depends on two main parameters - operational category and viscosity class.

CLASSIFICATION OF OIL GRADES API classification by operational categories (American Petroleum Institute). See more details here

CLASSIFICATION OF OIL GRADES BY VISCOSITY SAE classification (Society of Automotive and Transportation Engineers). See more details here

Winter - with the letter W (Winter). Oils that meet these categories are low-viscosity and are used in winter - SAE 0W, 5W, 10W, 15W, 20W, 25W

Summer - without letter designation. Oils that meet these categories are highly viscous and are used in summer - SAE 20, 30, 40, 50, 60.

Such oils are designated by a combination of winter and summer ranges: 5W-30, 10W-40

The multi-viscosity oil offers comprehensive stability under conditions of seasonal and temperature changes. For example, SAE 10W-30 oil is suitable for use as an all-season oil. At low temperatures, it has a viscosity equivalent to SAE 10W oil, and during operation it has the same lubricating properties as SAE 30.

Oil for walk-behind tractor engines, recommended by manufacturers.

Engines of these brands are installed on almost all currently produced walk-behind tractors such as Neva, MTZ, Salyut, Kaskad, OKA, Ugra, Tselina, Tarpan, Agat, Favorit, MKM and many others.

Motors from such well-known companies are tested and tested using the specified oils, so the result of operation in accordance with the manufacturers’ recommendations will be the best. Using motor oil of the specified grade and viscosity significantly extends engine life and improves its performance. Using too little or too much oil can cause serious problems, including engine seizure.

Manufacturers recommend not using oil with additives for 2-stroke engines, as it does not contain enough lubrication, which reduces engine life.

In gasoline engines for general use, only motor oils of classes SE, SF, SG should be used.

Categories of motor oils for gasoline engines

Categories of motor oils for diesel engines

We provide information on the oils used from the website of the manufacturer of Patriot brand walk-behind tractors and cultivators.

Patriot engine oil for 4-stroke engines (information from the official website)

Special high-quality motor oil for use in modern four-stroke gasoline and diesel engines with air and water cooling, installed on lawn mowers, cultivators, generators, walk-behind tractors, mini tractors and other equipment.

The increased content of additives reliably protects the engine under extremely difficult operating conditions, providing excellent anti-wear and anti-corrosion properties and increasing the oil service life before changing it.

The special formula ensures the stability of the oil film.

1.Preventing the formation of soot, varnish deposits and sludge;

2. Cooling of pistons, crankshaft bearings and other engine parts;

3. Maximum effective engine protection against wear during cold starts;

4. Reduced noise when the engine is running;

5. Extending engine life;

7. Impeccable engine cleanliness.

WE RECOMMEND TO CHANGE THE ENGINE OIL AFTER THE FIRST 5 HOURS OF OPERATION. CHANGE THE ENGINE OIL ONCE A SEASON OR AFTER REACHING 25 OR 50 MOTOR HOURS, DEPENDING ON THE OPERATING CONDITIONS OF THE MOTOR-BLOCK.

Frequency of oil change in walk-behind tractor engine

A few more recommendations from manufacturers regarding the use of oil in engines of walk-behind tractors and cultivators:

Please note that there are engines that have an additional gearbox built in, which also requires periodic oil changes. Here is an excerpt from the owner's manual for the Honda engine:

Lifan

These motors for walk-behind tractors appeared relatively recently, but are already very popular among gardeners and commercial organizations involved in agriculture. Let's consider the main characteristic features of these motors:

• products are available in various capacities;
• there are both diesel and gasoline units here;
• motors have a long service life;
• moderate power and operating speed;
• fairly low cost of the devices;
• the versatility of these devices;
• improved thrust of Lifan engines;
• compact dimensions (motors are easy to install).

Also, these installations are not highly voracious during frequent use (the engines do not consume large amounts of fuel or oil, compared to other similar models from other manufacturers).

Important! Despite the large list of qualities of such power plants, the models appeared on the Russian market relatively recently, which is why they are not widely used. Also, during operation, it is necessary to monitor the condition of the spark plugs; there are often cases when they are flooded.

Another manufacturer of power plants for Salyut brand walk-behind tractors. These units are in great demand. They are characterized by the following distinctive features:

• moderate power and operating speed;
• relatively low cost of devices;
• long service life of motors;
• availability of all consumables and spare parts for free sale;
• unpretentiousness to Russian fuel;
• engines do not consume large amounts of oil;
• relatively small size of power plants;
• Due to the motors, good cross-country ability is ensured.

CHANGING OIL in the Lifan-168F2 engine and the gearbox of the AGAT walk-behind tractor. Track of walk-behind tractor AGAT 发动机换油力帆-168F2

Despite the large number of positive aspects, when operating these motors you can also encounter some disadvantages. The most pronounced disadvantage is the high cost of spare parts (in order for the engine to last a long time, consumables need to be changed quite often).

It is worth noting that not all brands of motor units for Salyut walk-behind tractors were considered here; there are also other manufacturers of power plants, however, their characteristics and performance are somewhat worse than those of the models mentioned here.

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.

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 viscosity

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

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.

By composition

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

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.

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.

Advantages and disadvantages

The Oka MB 1D1M10 walk-behind tractor is quite popular in many regions of our country.

MB 1D1M10

This is no coincidence, because it has a number of obvious advantages:

• The presence of a chain gearbox, as well as a V-belt drive.
• Adjustable steering column;
• The design of this walk-behind tractor includes a box-shaped muffler, which can significantly reduce the noise level (by about 30%).
• Availability of a wide speed range. The highest speed is used to transport goods of various types.
• Sufficiently high maneuverability in confined spaces, thanks to the small turning radius.
• Possibility of aggregation with the device of a wide variety of equipment.
• The dimensions are small enough to allow the unit to be transported in a passenger car.
• A large number of certified centers throughout the country, which has a positive effect on the speed of provision of repair, maintenance, etc. services.
• The presence of an automatic decompressor, facilitating the starting process.
• The cost of the unit is quite reasonable for the majority of the population.

As for the shortcomings of this walk-behind tractor, they are entirely formed from personal feelings during the work of specific people.

It cannot be said that there are any obvious disadvantages, but some users of this technique note certain points:

• The weight of the walk-behind tractor is quite small, which causes certain difficulties when working with heavy areas of soil.
• Some are unhappy with the presence of drive belts in the design, which wear out quite quickly. In principle, there is some truth in this, but belts are initially positioned as a consumable material. In addition, the walk-behind tractor comes with several spare parts.

In principle, the existing shortcomings are more than covered by a large number of advantages. In addition, the cost of the Oka walk-behind tractor is very low, and the issue of price has become increasingly decisive lately. This issue is especially acute in rural areas, where, in fact, the walk-behind tractor will be used.

What kind of oil to pour into a walk-behind tractor engine

Manufacturers of walk-behind tractors and mini-tractors prescribe the use of motor oils for both gasoline and diesel products. The motors are being tested at the factory. At this time, lubricants are used that are recommended in the instructions. Some manufacturers recommend their own brand of oils. The Patriot walk-behind tractor is equipped with an engine of the same name and requires Patriot 5W30 SJ/CF, Patriot Supreme HD SAE 30 4T oil.

For gasoline engines

For walk-behind tractors running on gasoline, it is recommended to pour the following types of liquids into oil containers:

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.

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:

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.

Motoblock Agat

The manufacturer of Agat walk-behind tractors is the Russian enterprise OJSC GMZ Agat, which this year celebrates its 50th anniversary. Since its opening, the main specialization of the plant has been units for engines of various models of military aircraft.

Since 2002, the company has expanded its own range, having received an application to create walk-behind tractors for the Salyut brand. Another 10 years passed and the plant decided to make its own brand “Agat”, releasing a line of walk-behind tractors made using innovative technologies on modern high-precision equipment.

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

For the Neva MB-1 unit you need to prepare TAD-17I or TAP-15 V. The volume of lubricant is 1 liter. Salyut 5 and Belarus 08N-09N uses M-10V2 and M-10G2 in warm weather. In winter - M-8G2. The Oka MB-1D1 is filled with the TAD-17I or TAP-15 V transmission. The gearbox of the Tselina MB walk-behind tractor is filled at the factory. No lubricant change required. Tarpan is refueled with TAD-17I or its analogues. The favorite is MS-20 or TAD-17I aviation oil.

Vario requires replacing 80W90 every two years. The best oil for the Patriot Garden unit is 85W90. The recommended composition for the Zubr gearbox is TAP-15.

A few words about the timing of replacement. In the Favorit gearbox, the first replacement is made after 25 hours of operation. Thereafter it is changed every 250 hours. Replacement works better on a hot engine. The hot waste is drained through the oil drain, and fresh is poured in through the fill hole.

In the Tselina device, the contents of the gearbox are first changed after 50 hours of operation, then every 200 hours. Ugra and Oka are replenished daily with a small amount. A complete replacement is done after 100 hours of operation.

What kind of oil to fill in Neva walk-behind tractors

The quality of the lubricating fluid in the walk-behind tractor gradually decreases and becomes unusable. Along with this process, engine wear occurs. To prevent wear and tear, lubricant mixtures must be changed promptly. The instructions indicate the recommended brand and quantity. When purchasing, you must take into account the level of its viscosity and quality classification. For the Neva walk-behind tractor, you need to purchase oil for the gearbox and engine.

The Neva walk-behind tractor is equipped with different motors. They require lubricants of different brands and manufacturers. They should be poured into the engine taking into account the viscosity and category. For example, the Neva MB-2 walk-behind tractor is equipped with an American Briggs (Bridge) engine, while the MB-23 is produced on the basis of Honda engines.

If a device with a Honda engine is purchased for a plot of land, it can be filled with SAE 10W-30 in summer and winter. The same universal remedy is suitable for the Lifan engine. Subaru produces lubricant for its equipment itself. With a Subaru engine you need to buy lubricant from the same company. Her brand is Ow20. It is suitable for winter and summer engine operating conditions. It is permissible to fill in 5w-30 from the same manufacturer instead.

The Briggs & Stratton engine is filled with SAE 10W-30 summer engine oil. For winter conditions, SAE 5W-30 is suitable. Its consumption is higher than that of other motors, so the level needs to be checked more often. If necessary, lubricant is added to the specified level.

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.

General description of the Lifan device

The engine for the Lifan walk-behind tractor with a power of 6.5 hp, the price of which in various stores ranges from 9 to 21 thousand rubles depending on the modification, has a classic layout: it is a single-cylinder carburetor engine with a lower camshaft and a rod valve drive (OHV diagram ).

Its cylinder is made in one piece with the engine crankcase, which, despite the theoretical possibility of replacing the cast iron liner, significantly reduces its maintainability when the CPG wears out.

The motor has forced air cooling, the performance of which is sufficient when operating in hot climates, even under heavy loads.

The ignition system is transistorized and does not require any adjustments during operation. The low compression ratio (8.5) of this engine allows it to run on commercial AI-92 gasoline of any quality.

Moreover, the specific fuel consumption of these engines is 395 g/kWh – i.e. for an hour of operation at a rated power of 4 kW (5.4 hp) at 2500 rpm, with the correct carburetor settings, they will consume 1.1 liters of fuel per hour of operation.

Currently, the 168F engine family includes 7 models with different configuration options and connection sizes, which have the following characteristics in common:

• Cylinder dimension (diameter/stroke): 68×54 mm;
• Working volume: 196 cm³;
• Maximum power output: 4.8 kW at 3600 rpm;
• Rated power: 4 kW at 2500 rpm;
• Maximum torque: 1.1 N*m at 2500 rpm;
• Fuel tank volume: 3.6 l;

How to change the oil in a walk-behind tractor

Change the oil in the cylinders of a walk-behind tractor on a hot engine. This applies to both two-stroke and four-stroke engines. The heated waste mixture flows well into the substituted container. The following actions:

Lubricant in the cylinders of walk-behind tractors of different designs is replaced in the following order:

You can drain the oil and add fresh oil in 15-20 minutes. If you replace used oil with low-quality products, problems will arise that lead to equipment repairs. This applies to engine lubrication and gearbox oil. Lubricants age and require timely, high-quality replacement. After how many hours you can add car oil, it is written in the manufacturer’s instructions. You need to read it so that the purchased expensive unit provides assistance for a longer period.

Used lubricating fluid is disposed of at special points.

Choosing the best oil for the 4-stroke engine of walk-behind tractors and cultivators

Four-stroke air-cooled engines require lubricants. Moreover, such that the quality meets the requirements that we will talk about. And then we’ll make a rating of the best oils.

Equipment owners prefer to use oil marked Sae, which must be poured into the engine at an air temperature of at least 5 o C. It includes a multifunctional additive package with anti-wear and anti-corrosion characteristics.

This fluid well protects engine rubbing parts from wear and overheating, ensures engine cleanliness and increases service life. Sae standard lubricants are produced with different types of base, which affects their market value.

Scout-5l oil also has exceptional lubricating properties, which has gained a high reputation among domestic owners of walk-behind tractors. It can be called a full-fledged analogue of Sae 30. It is comparable in quality, but is more affordable, which makes this product even more in demand. This oil in a 5-liter container costs 1,680 rubles, which in terms of 1 liter is only 336 rubles.

Modifications

Lifan 168F-2

The cheapest configuration with a connecting shaft size of 19 or 20 mm. The manufacturer's price is 9,100 rubles.

For more details about the operation of the Lifan 168F-2 engine, watch the video:

However, the rectifier required to charge the battery is not included in the delivery package.

What is the difference between two-stroke oil and four-stroke oil?

Some types of motor oil are designed for four-stroke power units, while others are intended for two-stroke ones. They are not interchangeable, and they should be poured in accordance with their intended purpose, because lubricants for engines with different operating cycles have different requirements. Thus, oil for four-stroke high-speed engines, which use a forced lubrication system, is designed for prolonged exposure and is designed to provide a more stable coating of parts. In 2-stroke engines, the oil comes with the fuel and must instantly dissolve in it, burning smokelessly with a minimum of deposits in the form of soot and ash. Therefore, a characteristic feature of two-stroke oils is their good cleaning and minimal content of aggressive additives. They, unlike 4-stroke fluids, do not contain ash, extreme pressure and anti-wear additives. This allows them to burn almost completely along with the fuel without the formation of soot and toxic exhaust.

A special feature of oils for four-stroke engines is the content of many organometallic additives, which are aimed at improving their physical and mechanical properties and increasing their efficiency. And if such a mixture is poured into an engine with a two-stroke duty cycle, it will lead to the formation of ash deposits on the surface of the piston and the walls of the combustion chamber. Increased accumulation of deposits, in turn, can provoke the appearance of various troubles, which can only be eliminated by carrying out complex and expensive repairs to the engine, walk-behind tractor or motorized towing vehicle. Soot, which clogs the air filter and settles in the grooves of the piston rings if you use the wrong oil product, also causes a lot of harm. The accumulation of soot is fraught with loss of mobility of the rings, and this is a direct path to reducing the power of the walk-behind tractor engine, deteriorating its performance, and even complete failure.

Classification of motor oils

The most important parameters of motor oil are the viscosity grade and the temperature range at which it can be used. In the marking, the number before the letter “W” indicates the temperature at which the liquid thickens. The number after the letter indicates the maximum temperature at which the liquid ensures uninterrupted engine operation. These indicators must correspond to those indicated in the operating instructions for the garden motor cultivator. It should also be taken into account that in winter and summer you need to use different high-viscosity lubricants. Such as Sae 30, Sae 40 are intended for use of equipment in the summer, and low-viscosity ones, for example 5W30, are intended for use in winter. A low-viscosity oil product will quickly evaporate at high temperatures and will not be able to provide complete lubrication of mechanisms. Too thick a liquid will become an obstacle to starting the engine at low air temperatures.

The chemical composition of the lubricant base is also important, as it affects the properties of the product and determines its effect.

Mineral motor oil:

Synthetics contain additives that prevent carbon deposits and protect the power unit from wear. Semi-synthetics are produced by mixing mineral and synthetic bases with the use of special additives.

Advantages of synthetic and semi-synthetic motor fluid:

Petroleum products marked Sae-30, which have a high viscosity and are intended for summer use, are excellent for 4-stroke engines of walk-behind tractors, cultivators and other garden equipment. They can be made on a mineral or synthetic basis and contain various additives. A liquid with this marking reliably protects rubbing surfaces from corrosion and rapid wear. The oil is distinguished by its ability to extend engine life.

The most popular brands of summer oils labeled Sae-30, as well as oils intended for all-season use, are described below.

CARVER Sae30

Summer mineral lubricant (produced in Russia), containing various additives with dispersant, antioxidant, and anti-corrosion properties. It forms a durable oil film that remains on the surface of parts for a long time. Provides reliable engine protection against wear and increases its resistance to heavy mechanical loads.

Ensures efficient operation of the power plant under any operating conditions.

Oil Scout-5l

Choosing the best oil for walk-behind tractors and cultivators

Having a cultivator with a Chinese or American engine or a walk-behind tractor with a Honda engine, you need to remember that the duration of operation of the walk-behind tractor is affected not only by the timeliness of troubleshooting, but also by the quality of the oil used, as well as the systematicity of its replacement. The difference is that an incorrectly selected mixture or improper lubrication of parts in friction zones leads to increased carbon formation, increased fuel consumption and rapid engine breakdown.

Lubricants for 4-stroke motorcycle engines are produced in a fairly wide range: from budget to more expensive. To choose a suitable product, you need to navigate the labeling and parameters indicating its main criteria. Thus, the marking “S” classifies a group of lubricants intended for gasoline engines, and the letter “C” for diesel engines.

A number of automotive lubricants also meet all the requirements for motor lubricants for motor-blocks Neva, Scout, Crosser, Patriot, Salyut, Zubr, Favorit, Dobrynya and other models equipped with a four-stroke air-cooled engine. To the question: “Is it possible to pour automobile oil into a walk-behind tractor?” experts answer - “Yes, only when using different types of liquid can different consumption rates and the degree of soot formed be observed.” But they do not recommend pouring transmission fluid into the motor of a walk-behind tractor, explaining that this type of substance is not intended to operate in the range of high speeds and high temperatures. If the transmission is poured into a single-cylinder engine, it will begin to burn intensely, precipitate, clog the channels and air filter, which can lead to serious damage.

DIY gearbox repair

Easy maintainability is one of the reasons why Cascade agricultural units have gained their popularity. When operating these walk-behind tractors, it is not difficult to independently adjust and repair almost any of its parts.

The most common cause of malfunction is wear of parts, which occurs naturally sooner or later. To increase the service life of the device, it is recommended to adjust it as needed during operation and carry out technical inspections at the required intervals.

Let's look at the most common breakdowns:

• problems with spark plugs (oxidation, contacts come off, the shape of the gap has changed);
• insufficient oil level;
• cylinder gasket wear;
• contamination of the fuel system (resulting in difficulty getting fuel into the carburetor);
• The chain or belt tension has weakened.

As a result of malfunctions in various parts of the device, several types of malfunctions are possible. Let's take a closer look at them:

1. Excessive heating of the transmission during operation is a malfunction that is caused by bearing wear or oil problems (low level or poor quality). To avoid interruptions in operation due to oil, it should be replaced. If the malfunction remains, it is necessary to disassemble the transmission, inspect the bearings and replace those that have become unusable.
2. Uneven running of the unit with stable engine operation is a problem usually associated with wear of the treads. It is important to consider here that you cannot work on worn out protectors. If everything is in order with the treads, there may be a problem of uneven pressure on each of the wheels.
3. Vibration of a walk-behind tractor during operation is a malfunction that occurs if the equipment attached to the unit is poorly secured. To avoid this, before starting work you need to make sure that the bolt connections are made correctly and securely.

Another problem that sometimes occurs is difficulty starting the engine. There may be several reasons for this, and in order to determine which one is interfering with the correct operation of the unit, it is necessary to check it according to the following scheme:

• inspect the appearance of the device and make sure there is no damage;
• make sure that the fuel tank is more than half full and the quality of gasoline meets that required by the manufacturer;
• place the walk-behind tractor on a flat horizontal surface;
• make sure that the fuel supply system is working correctly;
• check the ignition system - make sure that a spark is being supplied;
• Check the operation of the carburetor and, if necessary, adjust the fuel mixture.
