Belarus MTZ 421 and 422 has an overvalued release that enables you to move in uneven areas without any problems.
With high approval you can process fields with water. The next video check shows the work of MTZ 421 on a rice field:
The user manual must be examined by new owners so that they understand the principle of the design of Mini tractors MTZ 421 and 422, the rules for assembly, running, start, maintenance, etc. can be found here.
Min i-MTZ tractors are a simple and reliable technology so that they serve as long as possible. It is necessary to carry out technical work on time.
- The oil and fuel level should be checked before each output.
- Replacing the engine oil should occur every 125 hours of the Mini tractor. The manufacturer recommends using the Soviet M-10DM or M-8DM oils.
- You should also monitor the condition of the gear oil. It must be replaced after 1000 hours or before the start of the season. It is recommended to use TAP-15V or TAD-17i.

Reviews of the owners
Below you will find several reviews of owners of Mini tractors from the forums:
I worked on it in the third season. I use a dua l-circuit plow, a cutter, a car and a Chinese excavator.
A plot of 8 hectares in the country. He buys gardening without any problems. Snow cleans quickly and effortlessly. The basis for the house Grub an excavator. Everything works and there were no breakdowns as such. The only thing if a large amount of snow falls out, I want the wheels in front of a slightly larger diameter because they slide and often dig.
I am a businessman. There is always enough work in the village for this technology. That’s why I earn with it. Now I do the plowing of gardens and driving building materials, equipment or furniture from the city. I am satisfied with work, but there are several nuances.
Advantages: excellent traction, quiet movement, maintainability, efficiency.
Disadvantages: The fastening of the front frame and the gear is often relaxed (you have to tighten it regularly). In the event of large loads, a hydraulic distributor shows (during the heating of the oil, the bypass valve refuses and the hydraulics refuses to work).
