Abstract
In combination, a tractor having at its rear end an implement hitch and a lift system and an implement coupled at one end to the hitch and having at its other end a height adjusting system for controlling the working depth of the implement. The lift includes a first hydraulic cylinder and the height adjusting system includes a second or remote hydraulic cylinder. The tractor has a pump providing a source of fluid under pressure. An auxiliary services valve is in communication with the fluid source and a phasing valve, the two valves being selectively in communication with one another. The auxiliary services valve is operable to independently actuate the first hydraulic cylinder to raise the hitch or to coact with the phasing valve to serially couple the second hydraulic cylinder to the first hydraulic cylinder to provide synchronous actuation of both cylinders to raise both ends of the implement to a fully raised position.
