We describet forces affecting machine implements ans we consequently calculated measuring resistances during the ploughing. The deeper the subterranean the higher the linear growth of forces. If the subterranean rises from eight to ten centimetres, it will appear an increase in forces o f 59,61% in the horizontal plane and of 30,84% in the vertical plane. If the driving speed increases from 5,91 km/h to 11,38 km/h, i.e. 1,64 m/s to 3,16 m/s, the forces will intensity to 53,11% in the horizontal plane and to 25,8% in the vertical plane. We deducted an outstanding influence of soil moisture on the resistance of the duckfoot shares at all three stages." . "RIV/60076658:12220/04:00005272" . . . "Celjak, Ivo" . "12220" .
