Summary:Electrohydraulic regulating equipment for a plough articulated on the lift of a tractor. The regulated quantity is the torque of the diesel engine 23 determined from signals of the sensor 33 of the needle stroke of an injector 34, a microprocessor 21 also deriving the rotational speed of the engine from these signals. In conjunction with additional signals of a rotational-speed sensor 28 on the rear axle 25 of the tractor, the microprocessor 21 calculates correction values which eliminate harmful deviations of the working depth of the plough 14 during accelerations of the tractor 10, in changes of the ratio of the gearbox 24 and in upward or downward displacements.
