Heavy tilling sets Canis prepare the soil for sowing under different soil conditions. The main working elements are two rows of spring teeth ended with duck foot share, which cut and loosen the soil well. By using a parallelogram mechanism, the intermediate frame determines accurately the depth of the teeth in relation to the shafts in the range from 2 cm to 12 cm. In the machine used side deflectors to limit the pouring of the soil beyond the working width of the machine. The front string roller with a diameter of 370 mm and the front crusher blade facilitate work on compact and lumpy soils.
