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).
