Chisel plows with a chisel as a working body, loosen the soil without mixing the layers. The analysis of the conducted research concludes that the most widespread is a cylindrical surface of a chisel working body - a chisel with a constant radius of curvature. It is theoretically established that at the radius of curvature of the bit up to 0.1 m, the soil on the surface of the bit will move chaotically, while the curvature of the bit does not affect the percentage of wrapped plant debris. As the radius of curvature increases, the force of inertia decreases, therefore, the angle of soil rise decreases. For the radius of curvature of the bit bigger than 0.5 m, the force of inertia has almost no effect on the angle of the soil rise. Without the influence of the force of inertia, the soil particles begin to move more orderly, the soil and plant debris begin to move along trajectories corresponding to the shape of the bit, which increases the coefficient of wrapping plant debris. It is established that at the radius of curvature of the bit 0.5 m and at an operating speed of 2 m·s−1 there is an orderly movement of soil on the surface of the bit, which affects the percentage of wrapping of plant remains. The use of a chisel plow point with a cylindrical surface increases the wrapping of plant remains by an average of 17%.
