Recently, versatile cultivating tractors have become increasingly popular, which are most rationally used during the preparation of the soil for
sowing, during sowing, tillage tillage in small areas, as transport vehicles and to drive various mobile and stationary machines. Increasing the efficiency of using these tractors in primary tillage is possible by aggregating rotary plows to ensure smooth plowing. They have the following advantages compared to standard dump plows: the absence of “breakup” and “dump” furrows and wedges that impede the performance of subsequent operations for cultivating agricultural crops and require additional costs for their alignment; increased unit productivity by reducing
the idling to a minimum, without increasing the working width and speed. For the efficient use of the universal cultivating tractors of traction class 2.0 and 3.0 for primary tillage, we have developed a rotary plow with a symmetrical diamondshaped dump, performing smooth plowing without ridges at the lowest energy consumption. The novelty of the design is protected by a utility model patent.
