Abstract

The electrohydraulic control device is used in an agricultural tractor. It has an electromagnetically-operated control slider (30) with four control edges for operation of a regulating valve (21) from a neutral position in two opposing directions, for supplying pressure to or from the hydraulic motor (15). An electronic control (56) indicates the pressures in the motor and the direction signal for the regulating valve. The correction of the control is dependent on a positive or negative load and selection of the correct control edge of the control slider.
