The article describes the use of tubular elastic elements in agricultural machinery. Failure to comply with agronomic requirements when conducting the pre-sowing tillage and sowing may lead to a significant reduction in yield. One of the important requirements is the observance of depth of soil and depth of seeding. The use of tubular elastic elements in agricultural machines, together with systems for tracking relief and density of the soil, allows to observe the depth of soil treatment and depth of sowing on soils with different physical-mechanical properties in automatic mode. Furthermore, the use of tubular elements allows to increase the efficiency of self-cleaning of the working body from weeds, reduced the tractive resistance of the working body.
