Abstract
An electrically controlled auxiliary hydraulic system for both front and rear mounted attachments on a skid steer loader. An electrically actuated auxiliary control valve is coupled to the front and rear mounted attachments through an electrically actuated diverter valve. An operator can select between control of either the front or rear attachments by actuating a diverter switch located on a steering lever. The auxiliary control valve is then used to control the selected attachment by actuating forward, reverse and forward latch switches on the control handles. The selected attachment can also be operated in a high pressure mode by actuating a high pressure switch when extra horsepower needs to be delivered to the attachment.
