It is just a license built MTZ 82 from Minsk... if thats so, i wouldnt put money in it... It is not worth to develope a fancy looking cab with curved windows that are expensive to produce and replace, on this old MTZ. It would only make the cost of ownership higher, while the tractor itself has nothing more to offer.
If Bolgar tractors want to survive, they should go with either Carraro or ZF, buy an engine from Perkins, Iveco, Cummins, and invest in proper transmission and engine technology first.
There is absolutely no point to make an antique MTZ 82 more expensive by putting new sheetmetal and cab on it. If farmers want a tractor for dirt cheap initial purchase, dont care about ergonomics, and dont care about the parts price and availability, they buy an MTZ. If they want a modern cab, they can buy plenty of economy models of the bigger manufacturers, NH TDD series, Zetor Proxima, Same Argon which have a way better customer support, parts availability, resale value.
