Abstract
A backhoe loader is provided with a reversible operator's seat having a first working position facing the loader and a second working position facing the backhoe. A first hydraulic pump directs pressurized hydraulic fluid through a first supply line to loader control valves, stabilizer control valves and backhoe control valves that are mounted in series. A second hydraulic pumps directs pressurized hydraulic fluid through a second supply line to the first supply line upstream from the loader control valves. The second supply line is provided with a two-position solenoid valve. In its first position, the valve directs pressurized hydraulic fluid from the second hydraulic pump to sump. In its second position, the valve directs pressurized hydraulic fluid from the second hydraulic pump to the first supply line. The solenoid of the two-position solenoid valve is in electrical communication with a seat switch signaling the working position of the operator's seat.
