ABSTRACT:
The present invention provides a control apparatus for controlling movement of an implement. The implement is mounted to a subframe that in turn is joined to a frame portion of the vehicle. The subframe is moveable between the working position, where the implement is operable to perform work, and a second position. The implement has a hydraulic actuator for selectively moving a portion of the implement to perform work using controlled hydraulic fluid present in a hydraulic line connected to the hydraulic actuator. The control apparatus inhibits or allows hydraulic fluid flow in the hydraulic line as a function of the position of the subframe.
