The present invention relates to an electrically actuated and controlled auxiliary hydraulic system for controlling the flow of hydraulic fluid under pressure to mounted attachments on a skid steer loader. In one embodiment, an electrically actuated auxiliary control valve is coupled to the front and rear mounted attachments through an electrically actuated diverter valve. In a second embodiment, a front and a rear auxiliary control valve is coupled to the front and rear mounted attachments. An operator can select between control of either the front or rear attachments by selectively actuating the forward, reverse and latch switches on the control handles. A mode control switch electrically coupled to an auxiliary mode control circuit allows the cyclical selection between the disable mode, the momentary made, and the latch mode. In the disable mode, the actuation of the forward, reverse or latch switches has no effect. In the momentary mode, the operator controls the particular attachment during the time of the switch actuation. In the latch mode, the front attachment can be operated in a high pressure mode allowing extra power to be delivered to the front attachment.
