An actuator control arrangement comprising: a hydraulic actuator (100) having a housing (200) and a piston rod (300) axially moveable within the housing between a neutral position, a retracted position and an extended position with respect to the housing in response to application of pressure to the piston rod; the arrangement further comprising a check valve (130) moveable between a first position (130X) providing a flow path between a pressure source (HP,LP) and the actuator, and a second position (130Y) in which the flow path is closed off; and characterised by a mechanical link (800) between the piston rod and the check valve, actuated in response to the piston rod passing a predetermined retracted position in a negative stroke direction, to set the check valve to the first position.
