The need to build a mini-tractor came to me simultaneously with the acquisition in the early 80-ies of the garden plots (receiving, as they said then). Those coveted six acres it was necessary to develop and sustain. I wanted to build a country house. Without mechanized assistant in this matter to do would be difficult. Industries such machines at that time almost was not allowed to get them even an acquaintance, it was almost impossible unless you’re a war veteran.
In many respects the design of the mini-tractor determined that the building site there was no electricity, and therefore the engine of the tractor was to be driven for many construction machines: concrete mixers, circular saws etc. and that time I had the engine D-3 with all devices necessary for its operation: carburetor, magneto, radiator. Same engines for generator drives stood in the middle of the last century in those rural clubs, where there was no electricity, which is produced by using such engines to be able to “twist” movie. This motor became the “heart” of my motorized assistant.
