Beschreibung
Zusammenfassung:	A hydraulic two-way valve includes a pump connection, a tank connection, and first and second working connections. The working connections are connectable to a hydraulic cylinder of an agricultural vehicle lifting mechanism. The pump connection is connectable to a hydraulic pump. In a first position, the pump connection, tank connection, and working connections are shut off. In a second position, the pump connection is connected to the first working connection and the tank connection to the second working connection. In a third position, the pump connection is connected to the second working connection and the tank connection to the first working connection. In a fourth position, the working connections are connected to the tank connection and the pump connection is shut off. In a fifth position, the tank connection is connected to the second working connection and the pump connection and first working connection are shut off.
