Abstract
A control arrangement for a hydraulic power consumer particularly in agricultural machines, has a pressure medium reservoir which is connected with a member for supplying pressure medium from the reservoir to the consumer to thereby move the consumer in one direction. The consumer is also connected with a member for withdrawing pressure medium from the consumer to thereby move the latter in an opposite direction. The arrangement further includes a single valve unit which is operative for both communicating and discommunicating the consumer with the supplying member and with the withdrawing member to thereby alternately move the consumer in the respective directions.
