ABSTRACT:
An auxiliary hydraulic control system for controlling the flow of hydraulic fluid within an auxiliary hydraulic circuit associated with a particular work machine wherein such system includes a first bi-directional proportional switch actuatable to control the direction of flow within the auxiliary hydraulic circuit in either a first or a second direction and at a flow rate which is proportional to the amount of pressure being exerted on the switch in the selected direction, a second switch actuatable to provide continuous flow in the selected direction and at the selected flow rate, and an electronic controller coupled to the first and second switches for receiving signals therefrom, the controller outputting a signal to initiate continuous flow in the selected direction and at the selected flow rate when the controller receives signals indicative of the first switch being actuated, the second switch being actuated, and the first switch being released within a predetermined period of time after the second switch has been actuated. An interlock override feature is also provided whereby, under certain operating conditions, the continuous flow function will be allowed to remain active while an operator exits the machine seat.
