When operated by public utilities, the device is operated for a long period of time, this must be taken into account and refueled.

All attachments must be securely fastened. If the connection is wrong, there will be strong vibrations and the device may fail.

reviews

About the power, or rather the load. We worked with a tractor on 7-8 hectares, plus forage harvesting, cleaning, etc. (a small farm for 10 cows), with such work the tractor is loaded about 60-70%, but thanks to the neighbors who don’t use the tractor work with a low load, we achieve the recommended productivity. About plastic. Of course, such performance is immediately perceived negatively, but in fact these elements do not carry any load, except for protection from dust and dirt. And that is quite enough.

Device Belarus MTZ 320 and 321

The Belarus MTZ 320 and 321 mini tractor is powered by an electric starter. If it fails or is discharged, the engine can be started manually.

Two powerful halogen headlights are installed at the front.
The grille allows air to be drawn in to cool the engine while protecting the tractor from the ingress of small insects or clods of earth.
The gearbox has 12 positions: 8 forward and two reverse.
The maximum driving speed of the Belarus 321 is 25.2 km/h.
The mini tractor control levers are located near the driver’s seat.

advantages disadvantages

The 3022 tractor is a 4 x 4 machine, so it can haul heavy loads on a rough dirt track. When equipped with dual wheels, it runs great on sandy soils or surfaces with a lot of moisture. All spare parts are unified for better interchangeability, repair and maintenance costs are minimal. The not very high stability of the cooling system under high load is noticed negatively. However, this is corrected by replacing the standard cooler with a more advanced and powerful one. It is advisable to check all pulls on the threaded fasteners. All other malfunctions can occur if the device is handled improperly.

service

Belarus MTZ 320 and 321 mini tractors are high-quality equipment designed for long-term use by farmers. However, to maintain operating condition, regular preventive maintenance should be performed.

The engine oil should be changed every 20 hours. The manufacturer recommends using semi-synthetic options.
Gear oils should be classified as SAE 85W-140 API GL-5. It must be changed every 80 hours.
To avoid corrosion and sticking of the control levers, they should be lubricated with waterproof greases.

At the end of field work, preservation is carried out, namely: the tractor is cleaned of dirt, dried, drained of oil and fuel, parts are lubricated so that corrosion does not form, covered and stored in a dry place.

Overview of the model range of MTZ tractors

MTZ is a work with a long history that can rightly be proud of the devices he produced. No joke, every tenth tractor in the world is “Belarus”. The work was included in the top 8 companies that supply us with high-quality equipment.

MTZ 82 is one of the most successful developments that are produced here. In addition, it was only improved and modified – increased functionality, increased productivity, increased ergonomics. This work has been a recognized market leader in the tractor industry for over 70 years and increases its production every year, a significant part exported.

The first bike tractors produced by MTZ

In parallel to the production of chain vehicles, the company’s design team developed a bike tractor that is equipped with a assembled hydraulic system that enables smooth work.

The first seven test patterns of the Minsk bike tractor were assembled in 1949, and the mass production of machines with the name Belarus and the serial numbers MTZ-1 and MTZ-2 started after long tests in autumn 1953.

Equipped with a hydraulic system and air-filled tires, the MTZ-1 and 2 became an important stage in the development of the Soviet tractor industry. The appearance of a multifunctional 37-strong tractor, which does not require a follower for agricultural work and moves independently on public roads, was the beginning of the active use of these machines not only in agricultural production, but also in the construction industry. Traffic, industry and local economy.

Later on the basis of the MTZ-2, which had a low efficiency, low functionality and low movement speed, more advanced models were developed-the tractors MTZ-5, 5M and 5L (1956) with an output of 45 hp unit and an autonomous Drive of the tap wave (1956) and its high-speed modifications MTZ-5LS and 5MS (1959).

In 1959 the equipment of the MTZ-7 model series was published. The MTZ-7M, 7ms and 7Ls tractors contained in the line were manufactured until 1961.

Creation of a small tractor MTZ-622

The MTZ-622 tractor, also known as Belarus-622, is manufactured in the Bobruisk plant for tractor parts and assemblies. This industrial company was founded in 1945 and became part of the Minsk tractor work in 1972.

The product range, which is currently produced by OJSC Bztdia, includes large and small tractors, handling and harvesting devices as well as units, spare parts and wheel panes for the entire range of the vehicles produced by MTZ.

Working on the development of small tractors in the Bobruisk plant started in the early 2000s. The need to master a new type of equipment was created in connection with the intensive development of private agriculture and agricultural businesses, the extent of which was much smaller compared to the collective property of the Soviet period, so that the use of large special equipment was inappropriate.

Tractor MTZ at the international agricultural exhibition in Serbia (Novi Sad). In the order from left: MTZ-622, MTZ-422, MTZ-320.

Production of minitractors began in 2007. Along with the debut basic model “Belarus-320”, equipped with a 36-horsepower engine, three other modifications based on it left the factory assembly line: loading, harvesting and loading-harvesters , which received a similar index.

At the end of 2008, the line of small equipment was expanded to include the Belarus-422 model with a 49.8 hp engine, and a year later a new compact Belarus-622 tractor was released, which received a 62.5 hp engine. It is designed for sowing and harvesting agricultural crops, harvesting forage, cleaning territories and transporting goods. A comfortable cabin with good thermal insulation and a durable engine allow this model to be used in any weather and climatic conditions in the temperature range fro m-25 to +45 ° C.

In the spring of 2021, a new modification of the Belarus-622 tractor was presented at the municipal equipment exhibition in Minsk, which differs from the basic version in having an environmentally friendly engine that meets the Euro III standard and wider wheels “shod ” in tires with a special “turf” protector.

At the end of autumn, when the harvest work ends, it is most profitable to acquire a used tractor and devices for it, but at the end of winter the prices for such devices increase.

The secret of the popularity of Belarusian Min i-Actractors

Various Belarusian small tractors of the MTZ, which were produced by the MINSK system, were subjected to different modifications so that the owners could buy a tractor of the most suitable model. The popularity of the technology is due to the following factors:

The weakest model of the cycle minibrat is equipped with a 1 2-liter engine. This traction is sufficient to perform all tasks associated with the cultivation of agricultural land with an area of no more than 1 ha.
By buying devices with a capacity of 22 liters, the owner receives full agricultural machines that can process up to 12 hectares of land.
Accessories expand the functionality of the device. Units of the MINSK tractor system are used by construction companies, supply companies, farmers, cattle breeding breeders, etc.
The enormous demand for MTZ tractors in fifty countries around the world shows that this technology is required. Every model is easy to wait, easy to repair, is economical and has a long service life. The price for Belarusian mini applications is also available for normal consumers.

With regard to technical features, use r-friendliness and costs, Belarusian devices can compete with Chinese analogues.
