To the calculation of plow adjustment in the horizontal plane: a) for plows with the number of bodies from 1 to 6; b) for multi-body plows. A is the center of mass of the tractor; In – tractor traction point; C is the center of resistance of the plow; D is the track of the tractor;eis the optimal bias;e_к – structural displacement; d is the distance from point C to the furrow wall; P_x – tractor traction force; R_x is the resistance force of the plow; R_y is the lateral component of the resistance force of the plow; L – shoulder side component of the resistance force of the plow
