MTZ 50 cab redesign. External tuning of the MTZ tractor: we improve it with our own hands. Steering tuning

Wheeled tractors of the "Belarus" brand are still used in our country, despite the fact that their production has long been discontinued. This circumstance speaks about high potential, incorporated in the design, its reliability and maintainability. The MTZ-50 wheeled tractor belongs to the category of universal agricultural machines of the ton. They are designed to perform a wide range of jobs:

• Transportation of goods on trailers and semi-trailers.
• All types of field work: plowing, cultivation, sowing, inter-row cultivation and much more.
• Drive of stationary and towed machines and units.
• Road construction works.

The tractor performs the above and other technological operations using a wide range of mounted, semi-mounted and trailed equipment. For this, the machine is provided with a trailing system, a towing device and a power take-off shaft for driving the units.

The Minsk Tractor Plant was established by the decree of the government of the USSR No. 1142 in 1946 and two years later produced the first products. The development of the MTZ-50 "Belarus" model began in 1956 in parallel with the design of a diesel engine. Technical and technological documentation was prepared in the shortest possible time and was approved by the industry research institute.

The experimental workshop of the plant began the pre-series production of a new row-crop tractor in 1958, after which it entered state tests. Based on the results of the latter and taking into account the comments of the commission, the machine was finalized and on its basis an all-wheel drive version of the MTZ-52 was created.

Tractor MTZ-52. All-wheel drive version

In accordance with the decree of the Council of Ministers of 11/14/1959, the start of production of the basic tractor model was planned for 1961, and the modernized one for the next. By the end of the five-year plan, the enterprise was ordered to bring the total annual production of cars of both brands to 75 thousand units.

In 1960, development work was carried out to install a half-track drive on the MTZ-50. Tractors of this modification were supplied to agricultural enterprises and other organizations on separate orders. The use of rubber-metal tracks has significantly increased the traction characteristics and economic performance of the machine.

In 1963, the modernization of MTZ-50 "Belarus" was completed especially for cotton growing farms. The fundamental difference from serial model- a three-wheel scheme, suitable for operation on a four-row system. At the Minsk plant, this tractor was produced for 8 years until 1977, after which its production was deployed in Tashkent at a newly created plant.

In 1964, the first production version in an all-wheel drive version came off the MTZ assembly line. This machine quickly became popular among machine operators and was appreciated for its high cross-country ability. Based on the described model, three crawler tractor T-54V for work in vineyards. The modification was produced with a track of 950 mm and 850 mm. The tractor was produced until 1985 and a total of 1,256,800 copies were produced.

Technical characteristics of the MTZ-50 tractor

Wheeled row-crop tractor the MTZ-50 model is made according to the classical scheme, the basis of which is a semi-frame structure. The load-bearing frame consists of two channels connected in the front part by a cast bar. In addition to the semi-frame, the skeleton of the tractor is made up of the clutch, gearbox and rear axle housings.

In the front part of MTZ-50 "Belarus" a diesel engine is installed longitudinally, closed by an alligator-type hood that folds forward. Mechanisms are located directly behind the diesel engine power transmission and a rear axle, as well as a single-seat cab to accommodate the operator.

Engine

The tractor is equipped with a four-cylinder diesel engine manufactured by MTZ brand D-50 of two modifications: with an electric starter and D-50L with a gasoline starter. Main technical characteristics of the engine:

• Rated power - 55 liters. with., maximum - 60 liters. with..
• The crankshaft rotation speed is 1700 rpm.
• The maximum torque is over 36 kgf.
• The working volume of the engine is 4.75 liters.
• Specific fuel consumption is not more than 195 g / e. l. with. h
• The injection pump is a four-plunger type UTN-5 with an all-mode centrifugal regulator.
• Injection pressure - 130 kgf / kgf / cm 2.
• Engine weight without technical fluids: D-50 - 410 kg, D-50 L - 470 kg.
• Working oil pressure 2.0 - 3.5 kgf / cm 2.

The power unit is equipped with a combined two-stage air cleaner. The cooling system is liquid with forced circulation of water or antifreeze, the radiator is located directly in front of the engine. Fan with permanent drive from the crankshaft through a belt drive.

Combined lubrication system: some parts are supplied with oil under pressure from a gear pump, the rest are sprayed. Oil purification is carried out in two stages using a mechanical and centrifugal filter.

The power supply system includes a fuel tank, a filter rough cleaning, fuel priming pump, injection pump, filter fine cleaning, vortex chambers and nozzles.

The engine is equipped with an hour meter, a valve for draining the coolant, a fan for forced blowing of the radiator, a thermostat, a water pump and a generator. Attachments provide work power unit and other tractor systems. So, the generator is driven by a belt from a pulley mounted on crankshaft... The device is designed to supply consumers with direct current.

Transmission

The torque from the engine to the drive wheels is transmitted through a chain consisting of the following mechanisms:

• clutch;
• coupling;
• gear box;
• rear axle.

The clutches and the connecting one are installed in one housing, which is connected to the power unit. The rear axle and gearbox have separate housings in the lower part of which there are housings for transmission oil.

The MTZ-50 tractor is equipped with mechanical box gear, which has 9 gears (including one direct) for moving forward and one - back. A gearbox is installed in the rear part of the gearbox, which doubles the tractor driving modes. Both mechanisms are controlled by one lever, while the gearbox is first switched on to an increased or decreased range.

The MTZ-50 tractor gearbox consists of the following parts:

• housing with crankcase;
• primary and secondary shaft;
• front and rear carriage;
• intermediate and inner shaft;
• driving and driven gears;
• gear shifting mechanism.

The torque from the engine through the couplings is fed to the input shaft of the gearbox, then through pairs of gears with different gear ratios it is converted and transmitted to the output shaft. The connection of pairs of gears, which are in constant engagement, occurs due to the movement of the carriages along the splines of the input shaft. Doubling the operating modes of the tractor is ensured by the use of a gearbox.

Chassis

The kinematic diagram of the MTZ-50 tractor is traditional for of this type machines and includes the following elements:

• Final drive with a pair of constant mesh bevel gears. To reduce noise, gears with spiral teeth (41 and 12, respectively) are used, the gear ratio is 3.42.
• The closed-type conical differential is installed in the rear axle housing and has 4 satellites. The device is equipped with a locking mechanism with two cam clutches, which is activated when the pedal is depressed. Deactivation occurs automatically when the leg is removed from the control body.
• The final drives are installed in housings at the ends of the axle shafts and consist of two pairs of cylindrical gears (one for each side). The gear ratio is 5.308, the teeth are straight, the number is 69 and 13, respectively.

The driving rear wheels are mounted on hubs, the rotation of which is ensured through the use of roller bearings... In the MTZ-50 version of the tractor, drive only to the rear wheels, in the all-wheel drive modification it is provided transfer case... Power is transmitted to the front axle via a propeller shaft.

The tractor is controlled by the operator by acting on the steering wheel, pedals and levers. The start of movement, maneuvering and deceleration of the agricultural machine is carried out by the following systems:

• Brakes. Disc, dry type, mounted on the final drive pinions. The drive is hydraulic, the operation is controlled by acting on the pedal.
• Steering. The system consists of a steering wheel, a worm gear (worm gear with a gear ratio of 17.5), a hydraulic booster, longitudinal and transverse rods and levers.

To reduce the control forces on the steering wheel, the mechanism is equipped with a separate-aggregate hydraulic amplifier. The system provides for a gear pump of the NSh-10E brand, with a capacity of at least 14 l / min. The actuator is a double-acting cylinder with a piston stroke of 19.5 mm from the middle position. The operation of the hydraulic booster is controlled using a single-spool distributor, which is installed on the axis of the worm gear.

Overall weight indicators

Model MTZ-50 "Belarus" refers to medium-sized tractors, which makes it possible to use it in the premises of farms to perform various operations. Basic geometric and weight parameters of an agricultural machine:

1. Maximum length (at the ends of the longitudinal rods of the hitch - at the back and counterweights - at the front) - 3815 mm.
2. Width (at the ends of the rear wheel axle shafts) - 1970 mm.
3. Cab roof height - 2485 mm.
4. Tractor base (distance between the centers of the front and rear axles) - 2370 mm.
5. The track of the front and rear wheels varies from 1200 to 1800 mm.
6. The minimum ground clearance is 465 mm.
7. The turning radius of the tractor is the smallest when performing a maneuver with braking of the inner wheels - 2.5 m.
8. Model constructive weight (in standard configuration without additional equipment and mounted loads on wheels and other suspension points) - 2790 kg.
9. Weight without operating fluids with a cabin and a roll cage - 3040 kg.

The geometric dimensions of the tractor, combined with the optimal weight, provide excellent traction performance, maneuverability and maneuverability. The agricultural vehicle is capable of turning with a small radius of the trajectory. This feature is very expensive when performing work on a limited area of ​​sites in off-road conditions.

The MTZ-50 "Belarus" tractor is controlled from the operator's workplace. It is located in a closed single-seat cab with a large glazing area, which is ensured good overview for the tractor driver in all directions. The operator is seated in a sprung seat, in front of which the following controls are mounted:

• Pedals: clutch, fuel control, differential lock, right and left brakes.
• Levers: gear shifting, trailer braking, rear PTO control, hydraulic coupling weight increase, hydraulic distributor.
• Back-up pressure adjustment handwheel.
• Steering wheel with switch sound signal and a direction indicator switch knob.
• Instrument panel, on which the ammeter, oil pressure gauge, temperature gauge and indicator light are installed.
• Mountain brake latch drive rod.
• Battery disconnect switch.
• Rear power take-off shaft shift knob.

The windshield of the tractor cab is equipped with a wiper, which is manually operated using a lever. To ensure a normal microclimate, a fan controlled by a separate switch is provided. Illumination of the workplace is carried out using a plafond installed on the ceiling. In general, the cab was quite comfortable for its time and provided the operator with normal working conditions.

The MTZ-50 model tractor was used to perform a wide range of field work using a variety of units. The list of attachments includes the following items:

• 3-body plows for plowing different types soils of several types.
• Mounted chopper mower.
• Trailed mower conditioner.
• Seeders of various types, including those with application function mineral fertilizers.
• Seeders-cultivators.
• Combined chisel and soil-cultivating units.
• Cultivators for continuous tillage.
• The harrow is mounted.
• Units for applying liquid fertilizers and pesticides.
• Transport and special purpose semitrailers.
• Tipper trailers and semitrailers.
• Hinged and trailed mineral fertilizer diffusers.
• Disc and segment-finger mowers.
• Rotary tedder rake.
• Square and round balers.

Attachments are mounted on the tractor using a special linkage system. Units requiring a mechanical drive are connected to the power take-off shaft. The towing devices are connected to the agricultural machine using a universal hook located on the transverse link of the suspension system.

Modifications of the MTZ-50 tractor

Minsk Tractors Plant constantly improved its products and produced MTZ-50 in several versions. The modernization of the machine was carried out in two directions: improving performance and increasing cross-country ability. In total, in addition to the basic version, three modifications of the tractor were released:

• MTZ-50L with D-50L diesel engine with electric starter.
• MTZ-52... It was equipped with a D-50 power unit with all-wheel drive, for which a bridge and a transfer case were installed in place of the front beam. Power transmission is carried out via a cardan drive with an intermediate bearing. Turning on front axle possibly in automatic mode or forcibly.
• MTZ-52L is an all-wheel drive version and differs from the previous model by the presence of an electric starter in the engine starting system.

Tractor MTZ-50X1. Cotton growing modification

All modifications are maximally unified in terms of the main nomenclature of parts, assemblies and assemblies. This approach allows to reduce the selling price for the final products of the plant and to simplify the supply of agricultural enterprises with spare parts and components. The all-wheel drive version of the machine has the best traction characteristics and is used in difficult terrain.

Operating experience MTZ-50. Advantages and disadvantages

Tractors of this model were developed based on technical requirements of the current moment, and for their time had excellent characteristics. MTZ-50 "Belarus" has a number of advantages over machines of other models, in particular:

• Minimum costs for the maintenance and operation of the tractor.
• High reliability of components and assemblies of the machine.
• Sufficient productivity, which allows you to perform significant amounts of work with relatively low costs.
• The tractor is designed for use in the absence of paved roads.
• The climatic design of the machine allows operation in winter and summer at extreme temperatures.
• The tractor can be aggregated with a wide range of attachments for agricultural and other work.

The machine is characterized by unpretentiousness, ease of operation and excellent maintainability. Recovery of a faulty tractor is possible in the field using a standard set of tools. At the same time, the MTZ-50 model has a number of features that should be taken into account when using it for its intended purpose:

• Insufficient engine power for work on heavy soils.
• High sensitivity of the starting engine to the quality of gasoline.
• The tractor driver must be careful when choosing the operating mode of the engine and gear.

Given the significant experience in operating agricultural machines of this model, the listed disadvantages can be considered insignificant. The machine operators note the unpretentiousness, high reliability and thoughtfulness of the design. The machine performed well in the middle lane and was delivered after appropriate modification to countries with hot or cold climates.

Conclusion

The MTZ-50 Belarus tractor is deservedly popular in our country and abroad, primarily due to its simplicity. Its operation and maintenance does not require highly qualified personnel. The high reliability of the model is evidenced by the fact that, despite the termination of its production more than 20 years ago, a sufficient number of machines are still in operation.

As attractive and powerful as the technique is, there will always be amateurs who want to make it even better. And this applies not only to cars. Tractors are also subject to modifications. Tuning MTZ will improve the technical characteristics of this unit, as well as its appearance.

Salon alterations

Every driver strives to make his cab vehicle more convenient. Some install a radio tape recorder, others change seats, and still others tint the windows. All this can be done with Tuning, the photo of which we presented in our article, affects other types of improvements. They install an audio system, a navigator, change and modify the backlight. True, in the process of these improvements, it is important to take into account some points.

For example, it is better to tint the windows, and not to hang them with curtains. This will eliminate excess dust in the cab. And it will look just as attractive and stylish.

Even the installation of an audio system has its own subtleties. The radio itself should be located in the place where it will be convenient for the operator to change its settings. The subwoofer is usually hidden behind the seat. At the same time, the speakers should provide a uniform sound.

When choosing a seat, you need to take into account the specifics of the technique. For tractors, chairs are suitable, high, comfortable, but small in size.

LED lights are usually preferred as backlighting. They save energy and give a lot of light, providing good illumination. For this purpose, it is recommended to use super-bright LEDs.

External improvements

External tuning MTZ implies, first of all, a change in the color of the body. The manufacturer usually offers equipment painted in one color. It's boring enough. And that is why its owners have a whole field for activity and flight of imagination. Tractors are painted in other colors, airbrushed - it all depends on the desire. The only caveat is the preparation of the body. The drawing is applied only on flat surfaces, otherwise it will be distorted. Therefore, everything must be perfectly prepared.

Do not forget about hanging additional elements. For example, installed moldings, grilles, door sills and so on will look appropriate. They even install wheel caps. But it is almost impossible to buy them in the store. Such elements are made by specially trained people.

Changing engine parameters

Tuning MTZ-82 and other modifications of tractors usually affects internal alterations, that is, a change in engine properties. For example, a diesel power unit is supplemented with a methane one.

This step allows you to replace up to 80% diesel fuel for natural gas.

Another way to tune the engine is to carry it out on time technical inspections and repairs. The increase in power is achieved In addition, it is possible to mount separate elements from other types of tractors.

Improving cross-country ability

Tuning MTZ also affects the improvement of cross-country ability. There are 2 ways in this direction.

The first is the possibility of installing middle wheels. As a result, it turns out that the tractor moves on 8 wheels instead of the usual 4. This step increases the area of ​​contact between the soil and the wheels.

For the same purpose, the so-called half-track is installed. For this, rubber-metal tracks are mounted, working together with tensioning devices. Thanks to this design, the pressure on the soil is reduced, and the tractor can move even in swampy areas of the fields.

Another way to improve flotation is to replace the bridge. Usually this part is used from GAZ-66. True, this MTZ tuning is quite difficult to perform. In this case, it is better to consult a specialist.

No matter how good the machines that came off the assembly line of the Minsk Tractor Plant were considered, but still domestic is domestic. Well, we have not yet learned how to do good technique! But you want to have in your hangar something really reliable, powerful and with such necessary options today as on-board computer with a non-buggy operating system, the ability to track the car when it is working in the field, a good sound system, climate control and much more! But all these achievements of technical thought are beyond the reach of a mere mortal! If you look at the prices for foreign equipment, which deserves attention, it immediately becomes clear that such a pleasure is not affordable. But I will hasten to convince you - do not give up your desires, strive to fulfill your dreams, even if it seems impossible.

If there is no money to purchase John Deere or New Holland

For creative owners who simply cannot come to terms with the fact that an MTZ tractor is working on their field, and not a Lamborghini or John Deere, I propose to start tuning their car. I just warn you right away that those who are not ready to put their hearts into their technique, do not have a lot of imagination and do not know how to work with a key and a screwdriver, will not cope with this task. Accept, this idea is not for you, and there is no point in reading this article. For everyone else, I write the following.
So, the first thing to do right away is to decide on the type of tractor tuning. For those who are not in the subject, I inform you that there are two types: external and internal tuning. As you might guess from the name, external tuning concerns external change techniques such as changing the body color, applying stickers, attaching a stylish new bumper and much more. Internal tuning is more difficult work, and not everyone can do it. It provides for changes in the design of mechanisms: engine revision, gearbox replacement, and the like.
Have you decided? Then let's move on to the next step.
Calculating the funds that will be spent on upgrades is also an important part that cannot be bypassed. To implement your plans, you will need good details, and high-quality tools, you cannot save on them.
Next, we go directly to the execution.

We fix the mistakes of the MTZ tractor designers

Probably the most difficult part of the job, which we can attribute to external tuning, is the alteration of body parts. It is carried out as at home, when ready-made parts are purchased from other tractors, trucks, passenger cars and are slightly modified, and in the factory, when the part is made to order. It should be noted that such tuning is one of the most expensive, and it requires certain work skills. In addition, in this case, good imagination is required. As for the result of such an improvement, it can be very diverse: you can turn a car into a laughing stock for others, or you can turn it into an object of envy.
See examples of such tuning *:

* - photos are given in order to show possible tuning options, MTZ tractor is not shown in every photo.

Today, not many owners of special equipment undertake such work, however, if the car body is rotten or has serious mechanical damage, then you just need to take advantage of this opportunity and make changes.

As you work, don't be afraid to be original. The only thing to pay attention to Special attention, - the accuracy of the welded seams (if such is provided by the new design) and their subsequent processing in order to avoid corrosion.
Feel free to use moldings, lower pipes, grille trims (unless the grille is worth paying attention to), sill covers. In reasonable amounts, such tuning will give a finished look to your updated tractor. Wheel caps are also an original step, the only problem with them is that they are difficult to find in the store, so immediately count on the fact that they will be made to order.

And now we make the tractor "bright"

For most owners of the MTZ tractor, tuning ends with the addition of new headlights and brake lights. I will note that they think in the right direction, this is a necessary thing, but you should not be limited only to this. Good foreign tractors already come from the factory with xenon lamps, but MTZ owners have nothing to boast of in this regard. But everything is fixable.

First, you need to choose a lamp that fits. From the owners of the already famous Belarusian tractor, we managed to find out that xenon d2s lamps are suitable (the same ones that can be installed on the Volkswagen Passat). An interesting solution can also be the use of "angel eyes".

The upper arc with fog lights will look very stylish. It will not be cheap, but it will give the tractor an impressive look, and additional lighting will not be superfluous in bad weather or at night.

I would like to note that with the improvement of lighting on special equipment, it is important not to overdo it. There should not be a lot of lights, their power should be small - you need to take into account the capabilities of the generator.

Improving the driver's cab

One cannot ignore the favorite topic of modern tractor drivers - comfort in the cab. In this case, you need to remember about comfortable seat, radio, subwoofer, navigator, additional lighting ... All these necessary things are missing in older models MTZ tractors.
You can find a suitable seat in car dealerships, and it is even better to use the services of online stores, today they provide a wider selection. When buying such a convenience, pay special attention to its dimensions; a tractor seat should be comfortable, but small.
As for the placement of the radio and speaker system, it is not so simple. According to the advice of experts, the subwoofer is best placed behind the driver's seat, the radio tape recorder - in the place where the hand can easily reach if you sit on driver's seat... The speakers should be placed in such a way as to ensure uniform sound in the tractor cab.
You can't say much about additional lighting. The vast majority of tractor drivers have already made their choice in favor of led lighting... You cannot argue with such a solution - it is economical and effective. The only caveat, it is better to take the so-called "super-bright" LEDs, their glow will be enough for normal cabin lighting. Well, it's better not to mount such on the dashboard.
As for this, I'm not afraid of this word, village tuning, like hanging curtains - give it up right away. Why do you need this dust collector! It is better to tint the windows - both stylish and comfortable.

We make the MTZ tractor "noticeable"

The need to work only with corporate colors, as well as the unspoken requirement for designers at factories to "create" only in the classic style, gave rise to a strong belief that the tractor should be painted in one color. On the body new car, except for the barely noticeable designations from the manufacturer, it turns out, there should be nothing else. This stinginess of thought prompts immediate action.
Let's put aside all the rules, and let our imagination run wild. In the photos below, you can see how other tractor owners have coped with this task:

As you can see, everything is in our hands. Drawings are made on the body (as in the photo) with a special tool - an airbrush. The paint is also used not ordinary, but specially designed (for painting bodies). You can find one in car dealerships or car markets. With an airbrush, everything is also simple, usually it is at the service station, or it can be purchased separately in stores that sell everything you need for service stations. There is only a problem with an airbrush artist who can apply the desired pattern to the body. You will have to look for him.

Whatever it was, but this type of tuning will immediately make your MTZ tractor noticeable, not only agricultural workers will pay attention to it, but also ordinary people who see it on the street. The disadvantage of artistic perfection is only a very high price.
Here I hasten to draw your attention to the fact that if you have already decided on airbrushing, then take care of the preliminary preparation of the technique for painting. The surface for drawing the picture must be perfect, otherwise it will be impossible to achieve the desired effect, and waste your money.
Another, cheaper and simpler type of tuning the MTZ tractor, and I will immediately notice that it is undesirable, is gluing stickers, hanging unnecessary LEDs, flags, as well as inappropriate fastening of mud flaps and much more (“ collective farm tuning"- they say among the people). In markets and car dealerships there are big choice such ornaments, and many lovers of quickly attracting the attention of others, actively use them. But it should be borne in mind that low-quality stickers quickly peel off, and it is extremely difficult to create some kind of general picture on the body with their help. Often, stickers only spoil appearance machines, speak of the owner of the tractor as a greedy and tasteless person. Lanterns, flags and other little things make transport look like a Christmas tree. Judge for yourself:

That is, we immediately abandon the idea of ​​fast tuning.

The article says a lot, however, I will hardly be able to list all the possible options for improving the MTZ tractor. I can only say that stay tuned for the latest in online stores selling tuning parts. Interesting offers often appear there. And also trust your imagination - it is it that is the main tool necessary to work on improving technology.

The MTZ 50 tractor is a general purpose wheeled tractor that was developed in the early sixties.

In 1961, the tractor passed field trials (test drive) and was put on the conveyor for mass production. Belarus 50 at MTZ (Minsk Tractor Plant) was produced from 1962 to 1985.

The long term of production of agricultural machinery was ensured by the technical characteristics of the MTZ 50 tractor laid down in the design.

During this time, more than 1 million 250 thousand copies of the MTZ 50 model were produced (52 modification with four-wheel drive).

The successful design possessed by the MTZ 50 tractor and quality engine allowed to create on its basis a large number of modifications for various agricultural work. Among them stand out:

• MTZ 60, 62 - export versions of the tractor;
• MTZ 50K - for work on steep slopes;
• Т50В, Т54В - tracked models for work in vineyards;
• MTZ 50X - modification with high ground clearance for working in cotton fields, produced with one front wheel;
• MTZ 50R - had a half-track undercarriage and was used in the cultivation of rice fields.

The Minsk plant produces models based on similar characteristics and purpose.

During the production period, the appearance was repeatedly changed or the cab was tuned in a modern way, but the tractor did not change the indexing:

• at the very beginning of the 60s, it had a semicircular radiator grill and a frameless base with a canvas roof;
• at the end of the 60s, a rectangular radiator grill was installed;
• in the mid-70s, the design and appearance of the hood was changed;
• in the late 70s, the tractor received an oversized frame cab and a fiberglass roof.

Unit specifications

Engine

A four-cylinder four-stroke diesel power unit of the D-50 model was installed on Belarus 50.

It has a volume of 4.75 liters and a piston split combustion chamber. Such technical design motor developed a power of 55 liters. with., while the weight is 0.410 tons and the fuel consumption does not exceed 8.0 l / h. The D-50 had a high technical service life. Before overhaul the characteristic was determined at 5000 hours.

• lack of power when working on heavy soils;
• difficulty starting the starter motor in winter time;
• low level of comfort for the operator in the cab;
• the need for frequent adjustment of the levers in the clutch basket and adjustment of the motor valves;
• low tractor performance on large areas (from 70 hectares).

Despite the inherent drawbacks of the tractor, it enjoyed great and well-deserved popularity in the country's agricultural farms for its versatility, reliability, ease of maintenance and repair in rural conditions. The successor of the MTZ 50 is considered a wide-universal wheeled

Tuning MTZ makes it possible to improve technical side tractor, since the converted equipment (for example, the engine) will help the driver to do his job better and faster, and external modernization will make it possible to improve the aesthetic qualities of the machine. Even the most powerful and high-quality technique, some craftsmen want to remake for themselves, thereby improving some of its functions or appearance. This applies not only to conventional vehicles, but also to special equipment such as a tractor.

How MTZ tuning is done

First of all, when it comes to reworking MTZ-892, or tuning MTZ-3022, many owners of such equipment think about innovations in the interior of the tractor. A comfortable driver's cabin is a guarantee of quality work. Some people need music to do the work, and the owner decides to install a radio tape recorder, some like a certain type of seats, someone is attracted by tinted windows so as not to languish from the scorching sun. The stove is also being re-equipped. On MTZ-1221, tuning can be carried out in the same aspects.

A navigator is also installed in tractors, improving illumination dashboard and the salon or, if it is absent, carry it out from scratch. It is important to understand that for a Belarus tractor, tuning requires careful attention to a number of points:

1. Window tinting is an important aspect of tuning. In this case, it is better to spend money on the services of specialists than to solve the problem with improvised means, hanging curtains on the windows: the fabric picks up a lot of dust and looks unpresentable.
2. Installation of a radio tape recorder requires a special approach. It is necessary to calculate the installation location so that it is convenient for the driver to reach and switch tracks. The subwoofer is located behind the seat, and the speakers are placed in such a way that the sound in the cabin is smooth and soft.
3. When choosing a specific seat, you need to understand where you will work at MTZ. It is recommended to install tall, small chairs. You can buy a seat in specialized car dealerships, sometimes it is worth making a choice in favor of online stores, a large and serious market will give you the best freedom of choice.
4. The role of lighting in tractors is traditionally used by LED lights, which make it possible to save energy and provide a sufficient amount of light in the cabin. When choosing bulbs, pay attention to super-bright LEDs - they will provide better lighting of the driver's seat. However, such luminaires are not suitable for dashboard placement.
5. The stove in the cabin often also requires re-equipment. Perhaps it warms too little in the cold season or does not blow enough air on you in hot weather. In any case, the stove in the cabin is the most important detail that must not be forgotten, as it plays a big role for the driver.

External tuning MTZ

Tuning tractors Belarus with outside implies a change in body colors. Traditionally, manufacturers supply tractors to the market, painted in plain boring colors. The car owner has a place to roam: he can fully realize his wildest fantasies when painting the body. Tuning the MTZ cab will transform the unit.

Depending on the desire of the owner of the equipment, the tractor can be completely painted in a different color, you can use airbrushing. However, it must be understood that the body must be carefully prepared before painting. A drawing, for example, can only be applied to a leveled surface, otherwise it will be distorted.

Hanging a number of decorative elements is also considered as tuning MTZ-80. For example, many people install moldings, grilles, make special door sills. Sometimes you can even find wheels with caps made by craftsmen with their own hands.

If you decide to tune the MTZ YuMZ T-40 tractors, it is important to be aware of how much money and effort will be spent on this. To implement all the ideas, you will need good quality parts and tools that will handle all the necessary work. You should not save on this.

The most difficult part of the work, when tuning on the MTZ-50 is carried out from the outside, as when working with any other model, is the modernization of the body and its components. You can do it yourself by purchasing the necessary parts in specialized stores and modifying them, customizing them to suit your needs. Sometimes it is better to use the services of specialists who will perform the most complex work on order. Successful external tuning of MTZ T-40 will be provided by the rich imagination of the tractor owner.

Modernization is sometimes not a luxury, but a necessity if the car body is rotten or has received severe mechanical damage.

You can seize the moment and make the tractor the way you would always like to see it. Attention should be paid to the welding seams: they must be made very carefully and correctly processed so that corrosion does not occur in the future.

Do not be afraid to use hinged decorative elements - the main thing is not to overdo it with the quantity and not miscalculate with the quality of these components.

Engine tuning and technical parameters

Each tractor has its own characteristics and you need to look at the engine from different angles. Tuning MTZ-40 will be radically different from tuning MTZ-3022 or MTZ-892. Usually alterations involve the insides power plant, that is, there is a revision of its main properties. Diesel engine MTZ-50 can receive a methane supplement. This makes it possible to reduce the consumption of diesel fuel and replace it with natural gas by 80%.

As an option, for tuning MTZ-1221, in relation to the engine, it is considered carrying out technical inspections and repairs, if necessary and when the scheduled inspection is due. Some tractor drivers decided what would work for them full change power plant, and made a choice in favor of more powerful engines. In practice, you can trace the tendency that the installation of a power unit taken from other special equipment at MTZ is the most correct decision in the case when you want to improve technical performance, and you can get by with a small alteration.

But such upgrades can be expensive - new motor will need to properly register and obtain a work permit. Sometimes the amount is so exorbitant that it is easier to purchase a new, more powerful and modern tractor with it.

During the conversion of the MTZ-82 tractor, a special device is often installed in MTZ, which allows you to significantly increase the power of the power plant. This function is performed by a turbine at MTZ. Sometimes it is worth resorting to trick and taking elements of other tractors (for example, the MTZ-80 cab) and tuning the MTZ-82 or any other Belarusian tractor.

Among the main technical parameters, which are being improved, highlight the patency of the tractor. There are several ways to improve different models, including the performance of the MTZ-892 tuning operation:

1. Installation of medium wheels, due to which the tractor begins to move not on 4 wheels, but on 8. This makes it possible to increase the area of ​​interaction between the wheels and the soil, and the tractor becomes more stable.
2. Installation of a half-track. Used for the same purpose as the previous method. It implies the installation of rubber-metal tracks, which work simultaneously with the tensioning devices. The tractor begins to exert less pressure on the soil and can work in swampy areas.

Sometimes the alteration of the MTZ-80 implies the replacement of the bridge, which is taken from the GAZ-66. But the procedure is very difficult to carry out on your own, it is recommended to seek help from specialists in the field of agricultural equipment repair so that the revision is done professionally.

Steering tuning

Sometimes experts recommend carrying out such work as altering the steering of the MTZ-82, in other words, putting in order the steering column of an agricultural vehicle. Sometimes alterations of the MTZ-82 tractor steering column end with its adjustment so that the steering wheel is in a comfortable position.

However, for a number of craftsmen, this does not end there, alteration of the steering makes the work on the tractor more convenient. Redesigning the MTZ steering column will require some skills and a fairly significant amount of time, but the result will exceed all expectations. The stove takes about the same time, namely the process of its re-equipment.

The same applies to the revision of the turbocharger and the modernization of MTZ-80 in terms of providing it with special nozzles for the dispenser.
