MTZ-920: Technical features
Many farmers have asked questions in recent years: Which tractor is better to buy: known from MTZ-82 or a more modern model of the Minsk Plant-Mtz-920? What is this tractor good, what is a “more advanced” modification of the 82nd model, and is it worth overpaid? In this article you will not only find the answer to these current questions, but also a detailed description of the technical properties and properties of the MTZ-920 tractor.
The MINSK tractor work is one of the few large companies that not only survived after the collapse of the Soviet Union, but also repeated its production potential, the range and the sale of products, increasing the commercial extension to other countries. The MTZ was the first of the former Soviet companies that certified its products in accordance with the standards of the European Union, and received a number of international certificates in May 2000 about compliance with the quality of the ISO 9001. The tractors have been using the Belarus brand (in Soviet times – Belarus) since the same year.
One of the best MTZ tractors
Every tenth of the roller tractor on our planet is an MTZ tractor that comes from the assembly line. Nowadays, the actual MTZ catalog is the potential consumers of two dozen basic models of various tractors, bike and gear-from mini-mini format for high-performance energy-intensive grace class. We can say that the company is trying to cover all market segments, and this task is successfully performed .
If you familiarize yourself with the sales statistics, it becomes apparent that universal tractors of traction class 1.4: MTZ-82 (and its version of MTZ-82.1), which have become modern embodiment of the legendary MTZ-80-Belarus. are most popular on the domestic market. Together with the 82nd Belarus, another modern Model-MTZ-920 gains popularity.
Characteristics and scope of the “MTZ-920” tractor
The MTZ-920 is a universally proper roll tractor of the traction class 1.4 with a drive for four wheels. This model is considered a modernized version of the “Bestseller” of the Minsk Plant-MTZ-82, its further development. Both models use the same D-243 diesel engine without turbo load, of which other construction features are identical. With the exception of literally two or three.
First, a new synchronized gear is installed on the MTZ-920. It contributes to a more smooth movement of the tractor, without idiots and characteristic noises when changing the corridors. In addition, this model has an additional hydraulic circuit on the return coupling, and the tank of the hydraulic system is also increased. Tires are used a little wider than with MTZ-82. MTZ-920 costs only 30-50,000 more than the 82.
In addition, Belarus-920 has a lot together in its design and with many other tractors from the Belarusian manufacturer, especially with MTZ-892, MTZ-952 etc. They vary among themselves according to the parameters of engines, the presence or the absence of turbo loads. The MTZ-920 found its niche on the market mainly due to the fact that the diesel installed on it is quite economical, since it is from the perspective of fuel consumption and in the costs of its maintenance and repair. A significant plus – and the relatively low costs of the tractor, for which it pays off for a rather short lifespan.

The air conditioning system can and should be used in MTZ-920, since the cabin of the tractor is equipped with good seals and has decent properties of noise and thermal insulation. The Machmer machine operator is adjustable in height, pressed. The cabin is characterized by an improved interior with modern materials and corresponds to the requirements of the EU and the OESD.
There is a washing machine of the frontal and rear jars as well as door glasses with electrical drives. Further front jobs are attached to the brackets of the front lamps. The panoramic glazing of the cabin provides the machine in all possible aspects a really excellent check. The comfort is that you can work for a long time by “moving” the start of tiredness “for later”.
The possibilities of the aggregation of MTZ-920
The use of Belarus-920 with a variety of trailer, semi-sound and adhesion equipment is amazing with its impressive amount. In addition to the standard three-box plows “PKMP-3-40R” and “PLN-3-35P plow”, the tractor can be used with hinge plows: corrare plows and watches for smooth plowing.
With hinge, disc, garden and heavy eggs; With cultivists for continuous soil processing. With combined aggregates: cheese and soil processing. With seeds of all kinds of structures: exact sowing; pneumatic; Stareva; with an additional fertilizer application; dashed sowing. With a variety of mowers: exceeded Ivy; followed with a mill; Segment finger; Schindeln or half grinder. With units and diffusers for feeding floors (use of liquid organic and mineral fertilizers). With dremer or scooter press colleagues, rake ribs, packages with silos and senage mass, windshots of rollers. With snow spots, kunami, shock walls, loads of all kinds. Of course with tractor fans and semi trailers, usually o n-board and sel f-vital. And so on.
Reviews of the owners MTZ-920 and prices
There are several versions of this model from Belarus on the modern market. The most modern and demanded from them are currently MTZ-920.2.
Modification MTZ-920.3 in Poland. The engine compartment of this version is differentiated by optimized shapes.
Like any other tractor, MTZ-920 has its own positive and negative sides. The plus points include:
- High performance and endurance of different weather conditions and intensive operating modes;
- Decent performance and performance indicators, combined with good efficiency.
- Ultra-universal use. Thanks to the widest selection of devices that are compatible with the tractor, the MTZ-920 is practically suitable for use, as you say, “for all occasions”.
- Spacious and comfortable cabin, light and understandable control;
- Compared to competitors, the costs of the tractor and the sufficient efficiency of its use accessible; Fast repayment.
All types of praise from owners and machine operators deserve the “behavior” of a synchronized gearbox of the MTZ-920 equipment. After certain impressions, the transfer of the tractor is slightly “stretched” compared to MTZ-82; Switching is almost fine. Without habit, it even becomes incomprehensible: there was a change to a different course or not.
- According to the observations of one of the specialists of the MTZ dealer service “nurses” for only three to four years during daily business. After that, synchronizers and equipment of the 2nd gear are poured, the cast iron of the fork housing is also broken. The repair price costs at least $ 1,000: three synchronous of 100 (and only Belarusian is worth taking because “China” runs for a maximum of three months), the equipment of the 2nd Gear-25, the equipment and 12. 82- I, the 56th, 16th, 18th, all bearings, the body of the fork-80 each, but in another case you can $ 10 by replacing cast iron.
- Another disadvantage: There is not enough cultivation speed in the “MTZ-920” field. Namely: It is difficult for him to work quickly, and if slow, the engine sounds very loud, but there is no real speed.
- With a slightly filled with a diesel fuel, the tractor can stand, whereupon it is very difficult to start.
- Also, many express such a disadvantage as wider rubber compared to MTZ-82. As a result, the track of the tractor is somewhat wider and does not always “fit” into the row spacing. Some farmers had to put up with such inconveniences as self-adjustment of the rear wheels, so the tractor usually “fell” between the rows of sunflowers.
There is an opinion that compared to the MTZ-920, it is preferable to buy an MTZ 892 with a turbocharged engine. Since this tractor will be faster and more powerful than the MTZ-82 and MTZ-920. But as mentioned earlier, the presence of a turbine is seen by many as a disadvantage rather than an advantage. (They say that with a turbine, especially if it’s not a new one, it’s more trouble than good).
Prices for a new MTZ-82 tractor at official dealers of the Minsk company start from 1,500,000 rubles; on MTZ-920.2 – from 1,700,000 rubles. As for the prices of used tractors, there are very few advertisements for their sale. For MTZ-920 2010-2011 in good technical condition they ask from 700,000 rubles.

Reviews of the owners
semyon:
“Tractor Belarus MTZ 920 led the third year. I didn’t even expect such a functional unit. Of the advantages, I would like to note high capacity and performance, and economical maintenance. The cabin is understandable. You can install any problems on the car. “
Vadim:
“MTZ 921 Belarus tractor is a cool machine. It’s great to work with him in the garden. On diesel fuel – economical. It practically does not break more than other tractors.
Of the advantages, I note a low taxi – even on a farm, I freely stop in space.
Of the minuses – the air intake system is not thought out. “
Anatoly:
“The Belarusian tractor MTZ-920 is made in conscience. The advantages are obvious: affordable price, easy control, easy repair, high versatility can work in any weather. I consider the not fully developed design of the checkpoint a serious drawback – the programs are stretched, it has not worked for more than 3 years. If there is little diesel in the tank, the tractor will often stall and then not want to start. You need an intermediate speed when growing. Due to the wide rubber, the width of the rear track will have to be reconfigured, otherwise the wheels will not fall into the gears. But in general the technique is at a high level. “
