Abstract

Two hydraulic units are fitted in parallel and interconnected by an equalising system connected with the drive mechanism of the vehicle. Either side can be used to operate a required agricultural implement. Each equalising system incorporates an electronic control arrangement with a potentiometer device, an actual valve registering device and a nominal value device to form a comparison and regulate the control valves accordingly.
