Tractors Kirovets with reversible plows PPO-8-35 PERESVET and Gregoire Besson SPB9 plow in one furrow

Hello, all hard workers! Next to the furrow, of course, it is better for both the tractor and the land. Good channel, I always watch it, keep it up, a lot of useful and interesting  Furrow work is an anachronism, as a specialist in agricultural production, I worked in this industry from 1973 to 2014 and graduated from the mechanical faculty of the agricultural institute, studied the theory of both the plow and the tractor, and never plowed in a furrow on Kirovets. The furrow is 35 cm, and the wheel is 90 cm. It tramples both the furrow and 55 cm of already plowed land, so open your eyes, especially the operator, and do not say that plowing is no different.
