Substantiation of the Absolute Velocity of the Soil Thrown by a Spherical Disc of the Roller of a Ridge Roller Planter

For the finishing operation of the formation of the soil ridge of the required parameters and density simultaneously with sowing, a tillage roller has been designed, the novelty of which is confirmed by the patents of the Russian Federation No. 194330, No. 194348, No. 196712. The design of the rolle...
