Abstract: A reversible driving arrangement for a tractor or any other vehicle in which a driver's operating station (10) including a seat (11), control panel (13) and steering wheel (12) can be rotated between a forward driving position and a reverse driving position. The operating station (10) is rotatably mounted on a floor of the vehicle via a fluid pressure operated rotary actuator (14) which includes a radially extending vane (28) which can be pressurised on one side or the other to assist in rotating the operating station between the forward and reverse driving positions. The rotary actuator is preferably pneumatically operated and part (22b, 22c) of the operator's station (10) pivots upwardly to a retracted position prior to rotation between the forward and reverse driving positions to reduce the overhang of the station.
