Motoblock Luch MB 1 - technical specifications, description and reviews

Motoblock Luch

The Luch MB 1 walk-behind tractor is used for operation on small household plots, vegetable gardens and gardens for individual use, and again in areas located in swampy areas, shallow forest areas and in suburban areas.
This model is produced in Russia and is not very common. Special equipment is suitable for working with light soils. The Luch MB 1 model is distinguished by its ease of operation and small size. The economical and powerful motor installed in the walk-behind tractor allows it to be used to perform a variety of operations. The model is aggregated with a variety of mounted implements that allow:

clear and make furrows;
plow;
harrow;
dig up and hill up root crops;
water;
spray plants;
remove snow;
loosen the soil;
mow the grass;
transport goods;
spray the plants.

Working with Luch MB 1 equipment does not require specialized training. However, each attachment will have to be inspected and studied (the rules of use are described in detail in the operating manual). Otherwise, problems may occur when working with the walk-behind tractor.

In the factory configuration, special equipment comes with cultivators designed for turning and loosening soil, extension cords and specialized wheels. Various modifications of the Luch MB 1 model are distinguished by installed engines, which can be either imported or domestic.

Among the features of the model are:

ease of operation of the walk-behind tractor. Working with it does not require serious physical effort;
the presence of a chain reducer with a V-belt drive, ensuring smooth movements of the equipment;
quick-release wheels and a removable steering wheel make the device very compact and greatly facilitate its transportation;
the steering wheel is vertically adjustable;
wheels with pneumatic rubber tires and large tread provide good traction;
protective fenders installed on the wheels protect against dirt, extending the service life of the equipment;
reliable transmission with 2 front and 2 reverse gears;
powerful engines ensure efficient and productive operation of the walk-behind tractor.

Engine characteristics:

working volume – 0.316 l;
rated power – 3.7 (5) kW (hp);
rotation speed – 3200 rpm;
permissible motor tilt angle – 8 degrees;
cylinder diameter – 76 mm.

The unit of the Luch MB 1 walk-behind tractor is unpretentious and runs on A-76, A-80 and AI-92 gasoline.

There are certain rules when working with an engine. The manufacturer does not recommend refueling the tank while the engine is running and touching the spark plug bracket or ignition wire.

The Luch MB 1 walk-behind tractor is not very widespread in Russia, so there are relatively few reviews about this technique. However, they are mostly positive. Many owners of the model bought it in a maintained condition, but after that the walk-behind tractor served them for many years without causing any special problems.

The Luch MB 1 model has to be repaired on major holidays. At the same time, special equipment can easily cope with a variety of soil types, which allows you to quickly work out the funds invested in it. The walk-behind tractor works well in tandem with a plow, cultivator and cart. Some owners of the Luch MB 1 machine use it in winter.

Problems with the engine of equipment are extremely rare. The main point here is to control the oil level

It is important that it remains at least below the minimum mark, otherwise the engine will start knocking.

Sometimes problems arise with the tension roller. This element may simply crack. Among the disadvantages of the model, again, is some incompleteness of the design.

The walk-behind tractor works well on difficult soil and near trees. The strength of the structure and excellent maneuverability help with this. As a transporter, Luch MB 1 again copes with its responsibilities with dignity.

The special equipment itself takes up little space, so it is convenient to transport it in a car and store it in a small garage. At the same time, it is indispensable in a small area.

Clutch slippage, which again often occurs in this model, is regulated by shortening the chain.

Cost of new and used

The price tag for the Luch MB 1 walk-behind tractor is not prohibitively high. Currently, it is almost impossible to buy this model without working hours. At the same time, supported options are in active demand. Beam MB 1 in good condition can be purchased for 15,000-17,000 rubles.

Brief description of the walk-behind tractor, its purpose and scope of application

The Luch MB-1 walk-behind tractor is a compact, relatively lightweight unit for cultivating soil in personal plots and vegetable gardens, as well as for some other agricultural work. It is as simple as possible in design and quite convenient to use. Maintenance and repair are also not something complicated, requiring special knowledge or training. All you need to do is read the instruction manual. And spare parts are available and inexpensive.

Initially, the Luch MB-1 walk-behind tractor is equipped only with a soil cultivator designed for loosening and turning over the soil. But, complete with other additional mounted implements, purchased separately, this walk-behind tractor can not only cultivate, but also plow light “garden” soils; harrow; cut and clear furrows, hill up and weed rows; dig up potatoes and other root vegetables; mow; transport goods.

The compatibility of the walk-behind tractor with additional attachments is good, but when using them with the MB-1, of course, you must carefully follow the instructions contained in the operating manual for each attachment. A powerful and economical four-stroke engine allows you to use the walk-behind tractor in various household works.

Design features

Walk-behind tractors "Cascade" have 4 main components for control and movement. This:

The chassis consists of a frame and drive wheels. There are also additional components that transmit torque from the motor to the wheels. The unit is equipped with powerful wheels with large treads, which allows the device to be used even on heavy soils.

The transmission is reliable and transmits torque from the engine to the wheels, being an integral part of the rotation of the unit. Torque is transmitted using gearboxes and a chain, and the gearbox itself has four speeds and is installed in a special block on the frame. A large number of models also have a reverse speed, which allows you to increase the maneuverability of the device.

Control is carried out by the clutch handle, with which you can adjust the choke on the carburetor, adding or decreasing engine speed. Also, using the clutch handle, the wheels are blocked when you need to turn in one direction or another. The steering wheel can be adjusted to the height and other parameters of the user.

Thanks to all these points, operating the walk-behind tractor is easy and simple, even during prolonged work on the site.

Filling with high-quality fuel is also important. If these rules are not followed, then over time the device may fail and become unsuitable for use.

Lifan engines on a walk-behind tractor: installation, properties. Chinese Lifan engine for walk-behind tractor

Any competent summer resident digs up his own plot before the beginning of summer if he has a walk-behind tractor. However, rare people are able to purchase a new unit for themselves. It is for this mistake that summer residents use cultivators made in the USSR. On such walk-behind tractors, various difficulties with the engine often appear, but there are many circumstances for this purpose. The main reason for breakdowns is the service life, which has already expired for several years. Since recently, such problems have been solved by Lifan engines on a walk-behind tractor, since this is a profitable method of solving the problem without the help of others and forever.

Choosing an engine for a cultivator

Unlike walk-behind tractors, which can be used together with an active hitch, walk-behind cultivators are used only for cultivating land. They usually don't have wheels.

Engine for motor cultivator Mole

The Mole cultivator was produced in the USSR, but now neither the Mole cultivator itself nor the engines for it are produced. But it's not a problem.

For the Mole you will need:

Modern engine of the Lifan/Honda type with a 19.05 or 20 mm shaft
Special new pulley for Mole under the shaft of the new engine (for 19.05 mm and for 20 mm)
New belt A750

Answers to common questions:

What power should I take for the new engine? An engine up to 8 hp with a 19.05 or 20 mm shaft will suit you. But we would advise staying at 6.5 hp; more powerful is not necessary.
Wouldn't the old pulley work? No, it was for a different shaft diameter.
Why is the pulley double-grooved? There are Mole models with reverse speed, so special pulleys for Mole are always made with 2 grooves.
I want to take a 3 or 4 hp engine. 3 or 4 hp engines exist in nature, but are non-standard. And therefore they will cost more than the widely used 6.5 horsepower engines. Better take 6.5 hp.

Adviсe:

It’s better to take 4-6 belts at once. They are cheap, but not sold in every store.
There are a lot of instructions on YouTube for converting the Mole to a new engine. For example, here and here.

Engine oil

When your assistants have a walk-behind tractor, you need to constantly monitor the technical condition. Oil. a very important connection that needs to be changed just in time. He is responsible for the unit with lubrication, sealing, cooling and cleaning of motor parts.

When the device operates in unchanged mode, the oil remains in the cylinder and can burn out and oxidize, as a result of which the walk-behind tractor begins to smoke. Substances with resins also settle in personal materials, which leads to contamination. Therefore, it is recommended to use excellent foreign oils that already have the necessary additives in their composition.

When the candles are left wet

The following faults are identified:

Carbon deposits on spark plugs. Clean them with a rough surface and rinse.
The gap between the electrodes increases or decreases. It needs to be adjusted to the appropriate size.
Wiring insulation is damaged. Usually it is replaced with a new one.
There was a short circuit of the ground to the STOP button.
The ignition system starter is faulty.

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

Another option for a terrible engine start is that the carburetor throttle does not close completely.

Candles in a walk-behind tractor should not be wet

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

Malfunctions during operation usually appear when the node connections of the motor, overloaded, fail, which leads to failures.

When the engine begins to pick up and slow down on its own, this can be done by loosening the thrust and locking the levers. To fix this, simply adjust the control drive.

If the engine loses power, it means it is overheating. In this case, the engine may seize, which happens when the oil level in the crankcase is low, a Nadir appears on the connecting rod head, or the oil sprinkler becomes unusable.

Change of oil

Oil should be poured into the engine of a Lifan walk-behind tractor of high quality, all-season, preferably from a good manufacturer. The substitution is quite ordinary. Firstly, the old oil must be drained. Then the new one opens up and pours into the engine. It is better to do the function on a warm engine, but you should turn it off.

The amount of oil, as well as the quality of the required oil, can always be found in the notes on the engine. He also quite painstakingly outlines what else our client needs to do to carry out repairs and maintenance, so there should be no problems with this.

Magneto for walk-behind tractor - testing at home

The magneto on a walk-behind tractor is a structurally complex element that is in constant contact with high-voltage wiring and interacts with electricity. Due to operation of the walk-behind tractor in wet weather, accidental impacts and failures in the electrical power supply, this part gradually fails. It is quite easy to check it for serviceability, but the operator will have to act at his own expense and risk, because the only method of testing the part under field conditions will be very unsafe for the entire ignition system.

To check the magneto of a walk-behind tractor, you will need:

Carefully remove the cap from the candle screwed into its standard place and insert a small nail in its place. The latter must be clean, without signs of corrosion;
The nail must be installed at a distance of 7 mm from the wall of the cylinder of the standard cylinder of the walk-behind tractor unit;
Start the engine of the agricultural unit;
Check if a spark appears when starting the engine. It should be painted bright blue and clearly visible. If this is not the case, the magneto has failed.

READ Cascade walk-behind tractor stalls under load

If the magneto breaks down, it will need to be replaced. You can do this yourself. removing the faulty one and installing the newest part.

Maintenance and operation

This document must be studied by the owners before starting work. The operating instructions help you understand the details of the Luch walk-behind tractor, the location of its spare parts and the rules for carrying out technical work.

In order for the device to work correctly, it must be maintained.

The oil should be changed regularly in accordance with the operating instructions.
It is recommended to pour M-10G2k or M-10V2 oil into the engine. The crankcase volume is designed for a one-time fill of 1 liter. lubricant.
The engine oil must be changed in accordance with the operating manual.
It is recommended to pour TAD-17i or TAP-15v oil into the transmission.
If you do not change the transmission oil on time, the gearbox will produce a loud knock and cause excessive overheating.
Control levers must be lubricated with Litol-24 or Solidol.

First launch

In order for the Luch walk-behind tractor to last as long as possible, it is necessary to start operation correctly.

If you bought a car from the factory, be sure to fill it with engine and transmission oil, as well as gasoline.
You cannot immediately begin full operation of the equipment. First, a run-in must be carried out. It should last about 5-7 hours. During break-in, the parts of the device are lubricated, rubbed against each other and fit securely into the grooves. The recommended engine load should not exceed half the maximum power.
Thanks to the running-in, the operating time of the device without breakdowns is extended.

Basic faults

A distinctive feature of Luch walk-behind tractors is their maintainability and ease of assembly.

Therefore, every owner of this device should know the causes of the main problems and how to repair them.

Reasons why the engine does not start:

The spark plug does not produce a spark (check its condition and connecting wires);
The air damper opened slightly;
The oil level has dropped below the minimum mark;
Dirty or low-quality gasoline;
Gasoline does not enter the carburetor (the entire fuel system should be checked).

Gasoline in the tank is running out;
Dirt has entered the air filter;
A large amount of dust has entered the fuel tank;
The piston rings have become unusable.

Reasons for excessive vibration from the Luch walk-behind tractor:

Bolted connections have become loose;
The attachment is not fully secured;
The tension belt has become loose.

The weak point of the Luch walk-behind tractor is the belt drive. It often frays and fails.

Therefore, you should always have several spare belts on hand in case of breakdown. Before purchasing a belt, be sure to determine the correct size.

Basic faults

Servicing Luch walk-behind tractors is quite easy; That’s why owners need to know how to correctly identify the causes of problems and eliminate shortcomings. If the unit does not start, you can assume:

the spark is gone (you need to examine the spark plug and wires, battery);
the damper for air access is slightly open;
a lot of oil has been used;
filled with clogged or bad gasoline;
There was a failure in the fuel supply system.

It happens that the engine seems to be working, but not smoothly enough or with low power. As a rule, this is due to the depletion of fuel supplies in the tank. But you can also assume that the air filter is clogged, or that a lot of dust has entered the tank, or that the fuel rings are damaged (worn out). Normally, the “Beam” should not vibrate very much. If this still happens, you need to inspect the bolted connections and the coupling (fixation) of the suspended equipment.

It is not recommended to use Chinese-made spare parts for replacement. It is better to use unique parts, including head shaft bearings. The only exception is belts, since their characteristics are unified. But it is imperative to determine the dimensions with the utmost care. If repairs and service are carried out according to all rules, problems should not appear.

You will learn how to plow the ground with a Luch walk-behind tractor from the video below.

Engine for different models of walk-behind tractors - characteristics, replacement

A walk-behind tractor is a universal technique that can greatly facilitate land work. The Neva brand is in greatest demand among farmers.

Also, an important role is played not only by the choice of the unit itself, but also by the installation of a sufficiently powerful and reliable engine.

Engine characteristics for the Neva MB-2 walk-behind tractor

The engine for the Neva MB-2 walk-behind tractor has the following distinctive parameters:

power 6.5 l. With.;
volume 208 cubic cm;
gear reducer with low-type gears.

This modification allows the walk-behind tractor to be used for transporting cargo, hilling, plowing, and cultivating various types of soil, even the heaviest.

Engine Lifan

Lifan is the most popular motor with relatively low power and the ability to cope with a wide range of household tasks.

Lifan has the following characteristics:

four-stroke engine with one cast iron cylinder with an air cooling system;
power up to 6 l. With.;
internal shaft with a diameter of 20 mm.

The motor boasts increased service life and ease of use. It is not very noisy and uses a small amount of oil. Engine repair can be done with your own hands.

Engine Subaru

Subaru is great for tough jobs. The motors have two modifications:

Professional operation. This is a high degree of reliability and increased service life;
Consumer exploitation. Use only for seasonal work.

Subaru means high precision and long service life, reliability, economical fuel consumption, lightness and compact dimensions.

Engine Patriot

A distinctive feature of the units is that they have a separate lubrication system, which makes it possible to achieve high torque. There is no need to add oil to the fuel mixture.

Thanks to the use of light alloys, maneuverability increases. The technique is very light, but this allowed it to remain quite powerful. The walk-behind tractor is easy to operate regardless of the conditions.

Patriot engine characteristics:

gasoline four-stroke engine;
two forward and two reverse speeds;
tank with a capacity of 3.6 liters;
working volume – 198 cubic cm.

The tillage track is adjusted depending on the type of soil and crops.

But it is worth noting that the price of such an engine is much higher compared to other models.

Engine Honda

Honda – reliable, durable, environmentally friendly motors for use in Neva walk-behind tractors. The engine is characterized by high power, economical consumption of resources and long operating time without failures.

Replacing the engine and components is very easy as parts are available from many suppliers.

Honda is power, reliability, safety and easy control. It is distinguished by maneuverability and ease of operation. A reliable four-stroke engine consumes minimal fuel.

What kind of oil should I put in the Neva walk-behind tractor?

When servicing agricultural machinery, you need to select high-quality materials. This also applies to oil changes.

The selected lubricant must be suitable for the specific modification of the motor. The following types are distinguished:

for two-pin motors;
for four-pin motors.

Depending on the composition, oils are semi-synthetic and synthetic/mineral. The choice should directly depend on the season. So, synthetic ones are more suitable for winter. Also, on the contrary, mineral oil products are more suitable for summer.

What to do if there is no spark on the walk-behind tractor?

If after the tests it turns out that the spark has disappeared. then the cause of this breakdown must be sought in the main elements of the ignition system of the agricultural unit.

inspect the spark plug - it needs to be unscrewed using a special key;
the spark plug may be completely dry - this indicates that fuel is not entering the engine cylinder, that is, the fuel pipes are clogged or the carburetor is malfunctioning;
in some cases, the part turns out to be wet from gasoline and motor oil. The reasons for this are an excess of lubricant contained in the fuel, or its leakage from the engine oil sump directly into the cylinder. In this case, the operator must remove the spark plug and dry it thoroughly. After this, you need to dry the cylinder, intensively pull the starter cable several times on the engine with the spark plug turned out;
Most often, due to the lack of proper and timely maintenance of agricultural machinery, a thick continuous layer of soot and dried resinous deposits forms on the spark plug of a walk-behind tractor. To restore the candle, you need to carefully heat it with a lighter and wash off the remaining resin with clean gasoline. After this, the part will need to be dried and screwed into place. If this does not help, then the spark plug needs to be replaced.

READ What Can Be Made From an Engine From a Trimmer

It is important to be extremely careful when removing, cleaning, and reinstalling the spark plug. Any careless movement can damage the electrodes of the part, causing it to no longer generate a spark.

Motoblock Luch

If you want to know the characteristics of the Luch walk-behind tractor, you should familiarize yourself with its features in more detail. It is a universal mechanized tool that is used for cultivating land on small plots of land.

The model is excellent for working with light types of soil and can be used in swampy areas. It is advisable to include among the characteristic features of the product:

small sizes;
low power engine with low fuel consumption;
Possibility of operation using various attachments.

The walk-behind tractor is used on personal plots. Thanks to additional equipment, this walk-behind tractor can effectively clear the soil, form furrows, plow, loosen the soil, mow grass, remove snow, and also perform many other tasks. The initial configuration includes only a cultivator cutter, which is capable of loosening and turning over the soil.

History of the production of the “Soviet” walk-behind tractor

The Luch line of walk-behind tractors includes several modifications that are almost completely identical in their technical characteristics and functionality. It is believed that they received different names thanks to several enterprises that produce them.

Mass production of the models shown in the photo began in 1985, when the demand for this type of equipment among consumers increased significantly, which was due to the emergence of numerous private households. The second half of the 90s became very difficult economically for manufacturers of walk-behind tractors, which led to a complete cessation of production of models in the 2000s.

Be sure to read: Motoblock Neva and attachments for it

Most of the copies in use today were produced a very long time ago, but they still perform their functions and, subject to proper maintenance, do not require serious repairs. Analogues of similar design are still produced by Chinese manufacturers, but they are somewhat inferior in quality to their domestic counterparts.

Scheme of the Luch walk-behind tractor

From owner reviews

Beam MB 1 is quite widely in demand, and mostly has only positive reviews. Many people buy this model on the secondary market, since used walk-behind tractors are usually in good condition, and in terms of reliability they are almost as good as new ones. For example, from the stories of the owners, we can conclude that Luch MB 1, even in maintained condition, can last for many years without causing serious problems in operation. Low cost of spare parts, high functionality and endurance are the key advantages of the Luch MB 1 model.

An in-depth analysis of the majority of walk-behind tractor reviews shows that the frequency of malfunctions of the Beam MB 1 is quite predictable. And yet, before using the equipment, it is necessary to carefully inspect it so that later problems do not arise while driving on various types of soil, as well as in muddy conditions. In any case, the Beam MB 1 is worth the investment. The potential and endurance of this technique is so high that many people use it in winter.

As for the engine, there are no problems with it. The most important thing in it is monitoring the oil level - it must be at least at the minimum level, otherwise the engine will make a knocking noise.

Common problems with the MB 1 Beam include an unreliable tension roller that can crack under heavy load. The owners note the good handling and geometric maneuverability of the walk-behind tractor. The left handle of the steering wheel has levers A and B, which allow you to move forward and backward

However, it is important to remember that pressing two levers at the same time can cause damage.

Engine for Tarpan motor cultivator

The Tarpan cultivator has been produced for more than 20 years. The most common variation is Tarpan-03 with a Briggs&Stratton engine, but there are also options with cheap engines (Champion, Weima). An unusual design feature of the Tarpan is its vertical engine, like a lawn mower.

Unfortunately, vertical engines are much less common than horizontal ones and are more expensive.

If you have a Tarpan-03 with a Briggs&Stratton engine, then you need an engine with a 22 mm shaft with a shaft length of 71 mm (length from the skirt - 51 mm):

The Loncin LC1P70FA (5 hp) engine will install without modifications
For the Lifan 1P70FV-B engine (6 hp), you will have to trim the shaft a little

If you have a Tarpan motor cultivator of a different model or with a different engine, then:

You will need to measure the shaft length and diameter of the old motor. The diameter will be either 22 or 25.4 mm.

Answers to common questions:

Why is it so expensive? Vertical motors from all manufacturers cost approximately 2 times more than horizontal motors of similar power. We can not do anything with it.

Design of the Luch MB-1 walk-behind tractor

The main components of the device are:

Power unit.
Gearbox.
Clutch.
Control system.
Chassis.

Design of the Luch MB-1 walk-behind tractor

Engine

The power plant for the Luch MB-1 is a single-cylinder four-stroke engine from domestic and foreign manufacturers.

Attention! When working with a walk-behind tractor, it is necessary to install protective covers and special wings. It is prohibited to operate equipment without protecting the main units and moving elements.

Domestic modifications use motors of the DM and CADVI 168F-2A series produced by Kaluga Engine JSC. The power of the power plants ranges from 4.4 to 4.8 kW.

Engine DM-1K

Foreign models use power units manufactured by TECUMSEH and Vanguard (USA), Honda and Subaru (Japan), Lianlong and Lifan (China). The motor power ranges from 4.0 to 5.2 kW.

Gearbox

Motoblock gearbox repair

The gearbox of the Luch MB-1 equipment is designed to convert the rotational movement of the engine shaft to the wheels (cultivator). The device is equipped with a two-speed chain reducer.

Attention! The gearbox is initially filled with the required amount of oil. Additional filling is carried out after 25–30 hours of operation of the unit

For uniform transmission of rotational motion, a shaft unlocking mechanism is installed. The presence of this mechanism increases the maneuverability of the device on straight and curved sections with a load of up to 350 kg and speeds of up to 12 km/h.

Clutch block

The system is designed to transfer rotation from the engine crankshaft to the gear sprockets. Allows you to move forward and backward. The clutch is controlled by a lever on the handle.

Motoblock clutch Luch MB-1

Control system

Designed to change the modes of action, speed and direction of movement of a mechanical device. Consists of a steering wheel, control levers and gear shift knob.

A motor control lever is installed on the right handle of the steering wheel. The left handle has gear shift levers. The steering wheel height is adjusted using a nut connection.

Walk-behind tractor control levers

Chassis

Wheels or a cultivator are installed as elements of the Luch MB-1 chassis. Wheels can be pneumatic or solid rubber. They are designed to move the mechanism on a flat surface. For better traction, stamped steel wheels (lugs) are used.

A cultivator is used to loosen the soil and remove weeds. The device is equipped with two tillers and two cultivators based on a bolted connection. Installed on the output shaft of the gearbox instead of wheels.

Milling cutter for walk-behind tractor

Engine for MTZ walk-behind tractor (Soviet engine)

MTZ walk-behind tractors are still produced in Belarus to this day. But modern MTZ walk-behind tractors have a slightly different structure than Soviet ones - and most importantly, they are produced only with foreign engines (mainly Honda and Weima).

For the most common models of MTZ walk-behind tractors ( MTZ-05, MTZ-06 and MTZ-012) there is a special adapter:

Adapter for MTZ walk-behind tractor (Belarus) for installing a modern engine

Together with this adapter, any modern Lifan/Honda type engine with a 25 mm shaft and the required flange will suit you. You can view all suitable engines we have here.

Answers to common questions:

Will it work with a 9 hp engine (Lifan 177F)? Very often on the Russian market, 9 hp engines come with a non-standard bolt pattern on the cover for the Ugra walk-behind tractor. Such an engine will not simply fit onto the adapter. But if you have an engine version with a standard bolt pattern, then it will do. How to understand which flange? It’s easier to buy a 13-15 hp engine, they are a little more expensive than 9 horsepower.
Why is it so expensive? Adapters at MTZ are produced to order by literally one small enterprise throughout Russia.

Spare parts

The new walk-behind tractor comes with a specific list of parts required for further operation. Due to the fact that the production of these walk-behind tractors has been discontinued, this opportunity has also disappeared.

Basically, you can only purchase Beam from your hands, or on Internet sites specializing in the sale of special equipment.

Spare parts

The Luch walk-behind tractor, spare parts for which can now be purchased on the Internet, was supplied with a coulter, a set of cutters, and instructions for working with it. In addition, this kit included certain consumables:

Washers and nuts.
Limiter.
Latch.
Bracket.
Kingpin.
Belts, etc.

About the manufacturer

The Luch walk-behind tractor was produced at the Perm Motors OJSC enterprise , which was repurposed in the late 90s. Now, this plant is included in the united enterprise “Perm Motor-Building Complex”, which includes many specialized companies. Here are just a few of these companies:

Aviadvigatel OJSC is engaged in the development of aircraft engines.
OJSC Perm Motor Plant produces engines based on design data.
CJSC "Kaskad-PM" is a plant specializing in the production of walk-behind tractors and related equipment.

As we can see, the activities of the merged enterprise are very different. By the way, the Luch and Cascade walk-behind tractors are actually produced at the same plant, which makes them, in a sense, related.

Currently, the general management of the Perm motor-building complex is carried out by Russian Helicopters OJSC.

Peculiarities

The Luch walk-behind tractor, like many other domestic machines of recent decades, was the result of conversion. It began to be produced at the facilities of Perm Motors OJSC, which previously was exclusively engaged in the supply of helicopter engines. Consumers note that these devices:

are relatively inexpensive and assembled properly;
can be used at any time of the year;
they work calmly on all brands of gasoline, even AI-76;
equipped with the same attachments that are used for other Russian walk-behind tractors;
They extremely rarely create problems for owners (only occasionally there are mentions of the inconvenience and unreliability of individual copies).

Let's take a closer look at exactly how a walk-behind tractor of any model is constructed, regardless of size. The ignition circuit involves the use of special spark plugs. In addition to them, the system includes:

converter;
stator;
magnetic shoe;
button to turn off.

It is useful to consider other components using the example of the MB-1 model. This version, released back in the 1980s, is very simple in its technical structure. But such simplicity can even be considered a virtue. The clutch, which transmits the energy generated by the engine to the gearbox, is made of a pair of belts. And also in the clutch there is:

drive, front and rear pulleys;
gear pulley;
traction;
front and rear arms;
special springs.

The gear unit changes the gear ratio, simultaneously transmitting rotational energy to the wheels and working tools. The MB-1 model is equipped with a chain reducer, which, in addition to chains, includes:

body (assembled from symmetrical halves);
switching shaft and handle for its control;
force output shaft;
three blocks of stars.

The transmission is capable of operating in a pair of forward and a pair of reverse gears. The most important element of the chassis is the wheels; they can be either inflatable or made of solid rubber.

Engine for walk-behind tractor Agro (Agros)

Another once popular walk-behind tractor with a Russian engine, which has been discontinued. But this is a solvable problem.

In order to select a new Agro walk-behind tractor engine you need:

Buy a special adapter for the Agro walk-behind tractor (Agros) for installing a modern engine
Select one of the suitable (with adapter) motors in this group

And that’s it, you can bet. Installation instructions will come with the engine, nothing complicated there.

Answers to common questions:

Will it work with a 9 hp engine (Lifan 177F)? Very often on the Russian market, 9 hp engines come with a non-standard bolt pattern on the cover for the Ugra walk-behind tractor. Such an engine will not simply fit onto the adapter. But if you have an engine version with a standard bolt pattern, then it will do. How to understand which flange? It’s easier to buy a 13-15 hp engine, they are a little more expensive than 9 horsepower.
Why is it so expensive? Adapters for Agro are produced to order by literally one small enterprise throughout Russia (the same as at MTZ).

Motoblock Luch

The model is excellent for working with light types of soil and can be used in swampy areas. It is advisable to include among the characteristic features of the product:

Motoblock Ural

Ural-UMP-5V walk-behind tractors first began to be sold in the country immediately before its global redistribution at the dawn of the 90s of the last century. Since walk-behind tractors, as a convenient and cheap technical tool, were needed by many, they became very popular in the USSR. In just a few years, its sales reached 150 thousand units. The optimal combination of its characteristics contributed to the popularity of the walk-behind tractor.

The mini-tractor has a wide adjustable soil clearance, allowing you to control the device on different types of sites. But it’s worth noting that the basic Ural model is not particularly versatile. It can only transport goods and cultivate soil. This technique will not help you to mow grass or remove debris or snow using attachments; such capabilities are not provided. But if you remake the design yourself, adding the necessary fasteners, then you can expand its functionality.

The model is implemented according to the scheme of transmitting power to the wheels using a differential. Some modifications use foreign powerful engines, but domestic versions are the most popular due to the availability of spare parts, proprietary documentation and durability.

Modern walk-behind tractors with belt drive

In order to select an engine for a modern walk-behind tractor with a chain drive, you need:

Measure the shaft diameter on an old engine (it will be either 19.05 or 20 mm, less often - 25 mm on 9 horsepower engines)
Select a new motor with the same shaft size as the old motor

Clue:

If you had an engine with a 19.05 mm shaft, and you want to take a new one with a 20 mm shaft or vice versa, then:

Take a new engine with the required shaft
Buy a new pulley to fit the shaft size of the new engine (pulley 19.05 mm, pulley 20 mm)

Also, buying a new pulley is a good option if it is not possible to measure the shaft diameter on the old engine.

Answers to common questions:

Will the mounts from the old engine work? Yes, they will fit
My engine was weak, I want to install a more powerful one. If you want a simple option without modifications, then it is best to take the Lifan 170F-T (8 l) - this is the most powerful Lifan engine with a 20 mm shaft.
I had a weak engine, I want to install a much more powerful engine (13 hp, for example). In this case, in addition to buying a new pulley, you will also have to redo the engine seat. The task is not very simple, and the gearbox will receive loads for which it was not designed.
