One of the most common technical devices that helps farmers in planting and harvesting crops is the Cascade walk-behind tractor. The units of this Russian brand have proven themselves to be reliable, durable and durable products.

Motoblocks are very convenient to use. They have a steering wheel that can be adjusted horizontally and in height. The center of gravity is located close to the ground, which reduces the effort when cultivating the soil.


These walk-behind tractors are among the most practical

Which engine is better to put on a Cascade walk-behind tractor?

The internal combustion engines for the Cascade walk-behind tractor are all: gasoline, carburetor, single-cylinder, four-stroke, air-cooled. The motor is started using a pull cord. Operating the device will not cause much noise and requires an acceptable level of vibration.

At the moment, engines for the Cascade walk-behind tractor are not produced in Russia. Therefore, we have to turn to foreign manufacturers for help. But the parameters do not always match the unit. Due to the difference in seats and shaft diameter, you also have to buy additional fasteners. So, which engine is better to put on the Cascade walk-behind tractor?

In this video you will learn the pros and cons of the cascade walk-behind tractor: The most common types of engine installed on the Cascade are:

  1. DM-68. This part is of good quality and most suitable for installation. It has an enlarged transmission, high power, a 3.3-liter fuel tank, four speeds - 2 forward and 2 reverse.
  2. B&S 1/C. A very popular option. It is chosen by equipment owners, since the engine has increased power up to 6.5 horsepower, low noise level, and the ability to operate even at temperatures below zero.
  3. Vanguard OHV. The most powerful device (up to 7.5 hp), with a large fuel tank, which allows you to quickly and efficiently perform a variety of tasks.
  4. Honda GX-200. The most common species in Russia. A distinctive feature is low gasoline consumption and modest dimensions. Made in China. Its analog “Lifan 168 f-2” is also very popular due to its low price.

Lifan

Lifan engines help solve many problems of cultivating land, planting vegetables, and harvesting crops.


Lifan is one of the optimal engines for the Cascade

Lifan is a company from China, was founded in 1992 and has proven itself to be excellent. The company produces not only engines, but also cars, motorcycles and other units.

On the Russian market, this brand is famous for its parts for walk-behind tractors, since many land owners use this equipment.

If previously products from China raised concerns due to poor quality, now the situation has changed, which contributes to the mass distribution of the Lifan brand.

The company's engines for walk-behind tractors have different characteristics, so each model corresponds to a specific unit. It all depends on the fastenings. You can select compatible devices yourself or entrust this choice to specialists.

Power is usually measured in horsepower. The most popular engine has 6.5 hp, which is enough to carry out all the work. To save money, you need to decide for what tasks the walk-behind tractor will be used. The average price is about 9,000 rubles, which is considered a very inexpensive purchase when compared with other manufacturers.

The process of installing the Lifan engine on the Cascade walk-behind tractor is simple:

  1. Remove the used engine. This can be done with ordinary open-end wrenches and sockets. Disconnect the gas cables and remove the belt that transmits torque to the gearbox.
  2. Install a Lifan brand device. Reassemble in reverse order. If the fasteners do not match, they must be redone by drilling new holes or welding metal plates.

Since the Cascade walk-behind tractor has compact dimensions, the Lifan part is well suited for this particular unit when working on personal plots and vegetable gardens.

The engines themselves are developed by Japanese engineers, and Chinese industry has just adopted their experience. The devices can also be used in generators, as they are very reliable and durable.

Briggs

Briggs&Stratton Vanguard engines have a very wide range of applications when installed on various equipment. They are used in conjunction with a walk-behind tractor, a gasoline generator, a motor pump, a vibrating plate, and so on.


This engine is suitable for AI-92 gasoline.

This engine is a single-cylinder, four-stroke carburetor type. It uses a cast iron liner, which significantly reduces wear on the piston system. The crankshaft is located in a horizontal plane and has bearings, which increases efficiency. There is also an oil sensor and an air purification filter. The engine capacity is 205 cubic centimeters, and the power of the device reaches 6.5 hp, so it can be installed on medium and large equipment.

The OHV mechanism makes it possible to reduce the size of the unit, effectively fill the cylinder with a mixture of fuel and provide increased torque. High-quality electronic ignition determines clear and reliable engine starting. To make switching on the device easier, a decompressor was installed. Also, the enlarged muffler allows for almost silent operation. The device is quite small and weighs about 16 kilograms.

The fuel used is AI-92 gasoline, which is poured into a 3.6-liter tank. This ensures long and uninterrupted operation. Despite the not too low cost, this device will completely pay for itself, which is facilitated by its high quality.

How to install an alarm with auto start on a motorcycle? | Topic author: Jesarelah

In this topic we will tell you how to connect ALL of our alarms with automatic engine start or with feedback.

In fact, there is nothing difficult about this.

But, of course, if you have difficulties with electrical equipment and looking at the wires causes horror and fear in you. then it’s better to contact a specialist in your field)

All our alarms have a wiring harness (see photo 1)

Igor (Norville) So about the connection, there are a lot of colored wires coming from the signaling:

Red. this is a plus, we screw it onto the red wire going to the ignition switch;

Black. this is a minus, we screw it to the frame, to ground;

Blue. this is for the starter (provided that the engine will be started from the alarm button), we screw it to the yellow wire with a red stripe (in the harness coming from the throttle grip);

Orange. this is so that the alarm goes off when the ignition is turned on, and also there is a plus along it to turn on the ignition when starting from the key fob, we screw it to the black wire of the ignition switch;

You also need to cut the black wire with a white stripe coming from the ignition switch.

Pink. screw it to the wire (black with a white stripe) to the part that extends from the ignition switch;

Grey. screw it to another part of this wire;

Yellow(double). two double wires, screw one to light blue, the other to orange (this is the exit for turns).

Igor (Norville) And here is the standard diagram for connecting all alarms on a scooter:

Igor (Norville) And here is a video lesson on “how to connect an alarm to a scooter” (this applies to all of our alarms with auto start or feedback)

Vyacheslav (Dalton) It’s clear for a scooter, but for a motorcycle of the Virago or Alpha brand, what is the connection diagram?

Vlad (Ceinlys) Vyacheslav, You can install it on the alpha, only there the wires are marked differently.

Vlad (Ceinlys) and the connection diagram also corresponds here: https://www.moto-planeta.ru/uploads/forum/images/13290.

Igor (Norville) to everyone who asks how to install an alarm system. Watch the video tutorial. check out the diagrams.

Alexander (Ahalya) on an outlander scooter, antifreeze flooded the alarm unit, tried to wash it and dry it, but everything is useless; the question is that you can connect a new alarm to the standard connector without modifications

Vlad (Ceinlys) Alexander, it’s possible, the main thing is that everything coincides with the previous alarm.

Alexander (Ahalya) where to look for the blue wire? there are three blue ones.

Vlad (Ceinlys) Alexander, Is the blue wire in the moped or on the alarm?

Alexander (Ahalya) Vlad, I figured out the blue wire, everything works except auto start!! The gray wire must be attached to the black one with a white stripe before breaking or after if the black one is disconnected and connected after! Then the fuses on the alarm and on the starter burn, and the fish goes crazy. Now we need a starter fuse! What markings does it have?

Vlad (Ceinlys) Alexander, That video tutorial is not suitable for a Yamaha for auto starting, write to me in PM and we’ll figure it out.

Misha (Darko) no magician rozobratsa with alarm system THOR help install on Alpha

Engine Installation

To install an imported engine on a Russian walk-behind tractor, you need a pulley, a gas cable, an adapter washer, and a bolt on the crankshaft. If inconsistencies are found in the fastenings, you need to drill holes in the right places. When the frame of the walk-behind tractor is not compatible with the motor, then a transition platform should be used. It is better to use a steel product to reduce the heating of the unit and prevent the belt from burning.

First you need to remove the old engine. To do this, remove the protection casing and belts, unscrew the bolts that secure the belt and the crankshaft bolt, then remove the pulley. We remove the air purification filter and disconnect the gas pedal cable. Afterwards we remove the old engine.

Next, we place a new part in the vacant space. If it is installed on an adapter pad, it should not be screwed on immediately, since the drive belt will need to be adjusted.

Next we place the pulley on the shaft and tighten the bolt. We tighten the belt and adjust the tension level with the engine. Afterwards, we completely tighten the bolts on the transition area, the belt stabilizers, install the air purification filter and the gas cable, and firmly attach the motor.

Important! Self-installation requires special equipment and tools.

Maintenance

Technical service of the Lifan walk-behind tractor includes a number of measures aimed at preserving internal parts and preventing breakdowns, and specifically:

  • Checking the level and changing the oil in the walk-behind tractor engine.
  • Checking the oil level and changing the oil in the walk-behind tractor.
  • Checking, cleaning, replacing the air filter.
  • Cleaning sucks.
  • Cleaning, adjusting, replacing spark plugs.
  • Adjusting valves on Lifan walk-behind tractor.
  • Cleaning the fuel tank.

For maintenance, it is important to comply with the manufacturer’s fuel and oil requirements. What kind of oil to pour into the engine, depending on the distance, is carefully described in the user's manual. If you use the wrong oil or fuel, the walk-behind tractor will malfunction. Technical service must be carried out in accordance with the schedule in the instructions.

Engines for the Lifan walk-behind tractor have long proven themselves to be reliable power units that allow the MB to be used to its full capacity. These engines are installed both on Russian cultivators and on imported equipment. The highest power of the Lifan motor. 6.5 horsepower, which allows you to carry out various work on languid lands. Today there are not only power units on sale, but also MB from this company, we will look at their advantages.

Motor problems

Engines running on different types of fuel (gasoline or diesel) have different service life. For engines using diesel fuel, it is much larger, but it is gasoline units that are popular due to their lower cost and ease of operation and repair.

Typically, of all faults, two main types can be distinguished:

  • startup problems;
  • problems with smooth operation.

Problems in the fuel system

The first thing you need to do is check the spark plugs. If they are dry, this may mean that gasoline is not getting to the engine. The main reasons will be: lack of fuel, the supply valve was closed, the hole in the tank plug is clogged, unnecessary objects get into the fuel system.

For maintenance you should:

  • refuel the walk-behind tractor;
  • unscrew the fuel supply valve;
  • clean the gas tank cap;
  • remove all gasoline from the tank, having first removed the fuel valve, and wash it with clean fuel. Then blow out the jets in the carburetor using the fuel supply pump.

When the candles are left wet

The following malfunctions are identified:

  1. The appearance of carbon deposits on the spark plugs. They should be cleaned with a rough surface and washed.
  2. The gap between the electrodes has been increased or decreased. You need to adjust it to the required size.
  3. Wiring insulation is damaged. It is usually replaced with a new one.
  4. There is a ground short to the STOP button.
  5. The ignition system starter is faulty.

The rubber carburetor seals may also become loose, causing air to be sucked in. It is necessary to tighten the bolts, spark plugs and inspect the gaskets between the cylinder and the spark plug head.

Another option for poor engine starting may be that the carburetor air damper does not close completely.


Candles in a walk-behind tractor should not be wet

If the compression is broken, it will also be difficult to start the engine. The reasons are: carbon deposits on the valves, the intake valve is deformed, or the piston rings are already worn out.

Problems during operation usually appear when the engine's node connections, subject to overload, fail, which leads to failures.

Important! If you realize that the engine is starting to make noise or run jerkily, you should immediately turn it off and cool it, and only then try to repair it.

When the engine begins to pick up and slow down on its own, this is possible when the traction and the fastening of the levers are weakened. To eliminate this, simply adjust the control drive.

If the engine loses power, it means it has overheated. In this case, the engine may jam, which happens when the oil level in the crankcase is low, a nadir forms on the connecting rod head, or the oil squirter has become unusable.

Technical characteristics of Lifan walk-behind tractors

The range of Lifan pedestrian tractors is quite wide. The company presents the latest generation cultivators on the market, equipped with massive Lifan engines and have amazing technical properties.

Let's look at the technical properties using the example of the Lifan walk-behind tractor

This type of equipment is perfectly suitable for processing medium and small areas with any terrain and different types of land. Plowing with this unit is available to a depth of up to two hundred mm, which allows you to dig out only the grain layer of the earth, leaving the deepest layers of clay untouched.

READ Setting the Motoblock Speed ​​Controller

Thanks to a larger selection of hanging equipment, using a Lifan walk-behind tractor, you can do any gardening work, depending on the season and consumer needs. By changing the components, the motor-cultivator can be used all year round, from plowing and planting to snow removal in winter.

The standard set of walk-behind tractor devices includes:

  • incisors.
  • Wheels d350 mm for walk-behind tractor.
  • plow.
  • Mowing machine.
  • Potato digger.
  • Pump equipment.
  • Snow removal equipment, etc.

The power of the Lifan motor in the latest models simplifies the cultivation of virgin lands with complex mixed soil. But when working with a motor cultivator, do not forget about the need for maintenance.

Fuel supply problems

This is a common problem that novice walk-behind tractor users may encounter. More often than not, this is not a problem at all.

Remedy. fill the tank and open the valve.

If these measures do not help, you need to clean the air valve or fuel valve, it may be clogged. If these measures do not work, you may have filled with bad fuel that should be changed. If the reason for poor fuel supply is a damaged needle valve or floating carburetor, these engine parts must be repaired.

Stopping the engine

If the Lifan pedestrian tractor stops at one point during operation or start-up, this may be due to one of 3 main circumstances, namely:

  • Ignition system malfunction. you need to adjust the ignition timing.
  • There is a malfunction in the fuel supply system. determine the reason and remove it.
  • Compression failure. replace worn parts, adjust the gap or repair the valve.

Engine oil

When you have a walk-behind tractor as your assistant, you need to constantly monitor the technical condition. Oil is a very important component that needs to be changed on time. It is responsible in the unit for lubrication, sealing, cooling and cleaning of the motor components.

When the device operates in constant mode, the oil remaining in the cylinder may burn out and oxidize, as a result of which the walk-behind tractor begins to smoke. Also, substances with resins are deposited in the parts, which leads to contamination. Therefore, it is recommended to use good foreign lubricants that already contain the necessary additives.

Description

Agro walk-behind tractors are produced in Ufa at the Ufa Engine Production Association. This enterprise is a prominent representative of aircraft engine manufacturers in Russia.

The development of the Agro walk-behind tractor first began in 1996, and by 1998 it had already been put into mass production. Further, it has found wide application in farm lands and garden plots.

Motoblock Agro

A special feature of Agro walk-behind tractors is that the engines are not purchased from abroad, but are produced directly at the factory. Thanks to this, the price of the device can be significantly reduced. At the same time, the build quality remains at a high level.

Initially, the production of Agro series walk-behind tractors was carried out at the Ufa Engine Plant. The model was released under the Agros brand, but was soon renamed.

The UMZ-341 engine is installed on Agro walk-behind tractors. This is a single-cylinder, four-stroke device with an output of 8 hp. It successfully competes with imported models. There are simply no analogues to it among Russian manufacturers.

Recently, Lifan engines have become especially popular. They are an identical copy of the famous HONDA GX-220 model. At the same time, the price for the Lifan motor is significantly lower, which allows you to leave the price at the same level.

Thanks to little mechanization, the designers managed to achieve great reliability and enviable power, while maintaining simplicity in the control process.

With the help of greater weight and higher traction force, the device produces maximum mechanization of manual labor.

The Agro walk-behind tractor can:

  • Carry out cultivation;
  • Plow;
  • Hill up potatoes;
  • Carry out harrowing;
  • Remove snow;
  • Mow weeds;
  • Transport goods over distances.

What kind of oil to fill

For high-quality engine operation, you need to correctly select the oil according to the SAE classification. It is necessary to strictly follow the instructions for the walk-behind tractor. Lubrication depends on the type of fuel the unit is fueled with. When operating in different seasons, lubricants of different viscosities are used.

In summer, semi-synthetic oil SAE 30 5w30 is used. In winter, a lubricant consisting entirely of synthetic materials 0w40 is used.

This is interesting: do-it-yourself repair of the Cascade walk-behind tractor engine.

You should not skimp on the quality of the oil, since it determines the efficiency of work and the duration of the process without breakdowns.

User manual

Before using the MB, it must be assembled and ready for use. Once you receive the cultivator, pay attention to its power supply. It should have a sticker with a safety symbol on it. Latest modifications of the Lifan engine with a power of eight hp. With. Lifan have distinctive features that need to be taken into account when compiling MB. Modification of the Lifan nine hundred mm walk-behind tractor. One thousand 100 mm provides for the installation of additional equipment to expand the plowed harrow.

When working with a motor cultivator, it is important to follow the following rules:

  • Before each start, inspect the engine.
  • Beware of flammable objects while the Lifan engine is running.
  • Keep children and animals away from the MB while it is operating.
  • The tank can only be refilled when the MB is turned off.
  • Do not run the engine indoors.

Starting work without working in the Lifan engine leads to premature breakdowns and equipment failure.

Change of oil

It is very easy to change the engine oil yourself, without the involvement of specialists. First, unscrew the hole cap to drain the old used grease. Pour the oil prepared in advance through the neck to the required level (approximately 600 grams). As a rule, the filling crankcase has a slight inclination, which helps to avoid overfilling the lubricant. Then screw the lid on and you can use the unit again.

Attachments

“Agro” meets all the criteria according to which the unit can be called universal. Any attachment for this device is suitable, but the following devices work best:

  • potato digger;
  • front adapter;
  • reversible plow;
  • snow blower;
  • dump;
  • mower.

The AHM-4 mechanized block unit also performed well; it makes it possible to turn a walk-behind tractor into a mini-tractor in a short period of time. KH mowers have also proven themselves to be very good. A wide special brush ShchR-08 is useful for cleaning roads, as well as a universal trailer that allows you to transport payloads over rough terrain over long distances. Snow blower mounted on a walk-behind tractor; capable of coping with snow drifts up to one and a half meters high.

Characteristic features of the device

Motoblock "Luch" Motoblock MB 5040 "Luch", naturally, is very far from the standard. Although, all modifications of this walk-behind tractor are far from it. Many details require improvements, such as the muffler, which its owners change over time to a quieter one - the noise during operation is really quite disturbing.

Some small, but very important parts are made of not the strongest materials - duralumin connecting rods can quickly fail and interrupt field work, which is one hundred percent dependent on the walk-behind tractor. And there are no less positive aspects in the operation of this technology.

Its low price, thanks to which “Luch” and similar walk-behind tractors Caiman, Texas, Prorab, Viking, Forza, Sadko outperform more expensive modern equipment, immediately attracts attention.

Made in accordance with GOST, these walk-behind tractors are as strong as steel, because, surprisingly, they are made of steel and quite strong and high quality - the small and not the most powerful MB 1, as needed, can cope with a load weighing up to 900 kilograms.

For more information about the MB 1 walk-behind tractor, see

The same applies to cultivating the land - no matter how “heavy” it is, he will cope with the task at hand, although it will take time. But, when starting work, the Russian walk-behind tractor requires options and low maintenance, especially after a long period of inactivity. In general, it doesn’t matter what kind of technology.

How to adjust valves?

After a certain period, you have to adjust the Lifan engine on the walk-behind tractor, because malfunctions occur, that is, it begins to work incorrectly. In fact, there are not many problems due to which the unit may behave incorrectly. One of the main ones is incorrect valve adjustment. It is quite simple to carry out; all work is carried out in several stages:

  • The valve cover is removed.
  • The gap, as a rule, is from 0.02 to 0.12 mm according to all standards, so it is necessary to take some kind of measuring probe or device for accurate alignment.
  • Next, the adjustment itself is made using a screwdriver and a measuring probe, which should be placed under the valve. The screwdriver in turn unscrews the adjusting screw.
  • After adjustment, you need to return the cover to its place.
