The stabilizer control valve is located on the inside of the frame by the right rear wheel. | |
Face the rear of the machine as you sit in the seat in order to determine the left and the right controls for the operation of the stabilizer control valves.
The pilot accumulator allows emergency lowering of the implements while the engine is off. The key switch must be in the ON position in order to shift the pilot shutoff valve. When the pilot shutoff valve is shifted, pilot oil flows to the joystick controls.
The stabilizer control levers are located to the left of the operator seat. The right stabilizer control valve and the left stabilizer control valves are identical. The operation of the valves are identical.
Hold Position
Oil from the pump flows through line (13) to the stabilizer control valves (4) and (7). Oil from the pump flows to the pressure reducing valve (12). The stabilizer levers are mechanically connected to the stabilizer valves. Therefore, when the operator moves one of the levers the valve spool moves causing hydraulic oil to flow through the valve and to the stabilizer cylinder. In the Hold position, all of the pump oil is blocked at the stabilizer valves. The stabilizer valves have internal lock valves that prevent any movement of the stabilizers.
Down Position

| Illustration 3 | g01048145 |
Oil from the pump flows through line (13) to the stabilizer control valves (4) and (5). Oil from the pump flows to the pressure reducing valve (12). Move the stabilizer control levers forward to the DOWN position. Oil from the pump is allowed to flow to the head end of the stabilizer cylinders (2) and (3). Oil from the rod end of the cylinders pass through the locking valves on the return side and flows back to the tank.
Up Position

| Illustration 4 | g01048145 |
Oil from the pump flows through line (13) to the stabilizer control valves (4) and (5). Oil from the pump flows to the pressure reducing valve (12). Move the stabilizer lever rearward to the UP position. Oil from the pump is allowed to flow to the rod end of the stabilizer cylinders (2) and (3). Oil from the head end of the cylinders pass through the control valves on the return side and flows back to the tank.
