Note: If the casters of the mower deck float above the
ground, the hydraulic pressure of the weight transfer
valve is set at too high.
•
When you are cutting flat turf, when the cutting deck is
scalping the grass, or if the quality of cut is uneven from
side to side, increase the weight-transfer pressure at the
lift manifold.
Note: Increasing weight-transfer pressure also transfers
the weight from the casters of the cutting deck to the
wheels of the traction unit, thereby improving the traction
of the traction unit.
Adjust the weight-transfer pressure as follows:
1. Set the parking brake, set the PTO switch is in the O
position, and lower the cutting deck.
2. Locate the lift manifold from under the machine,
inboard the right frame channel, behind the front axle
(Figure 15).
3. Connect a pressure gauge to the test port at the rear of
the lift manifold (Figure

3. Remove the cap from the
weight-transfer spool
4. At the front of the lift manifold, remove the cap from
the weight-transfer spool
5. Loosen the jam nut at the bottom of the weight-transfer
spool (Figure
6. Start the engine and set the throttle to
7. Use a hex-socket wrench to adjust the lift valve of
the weight-transfer spool until the desired pressure is
measured on the gauge; refer to the chart that follows
for the recommended pressure setting for the cutting
deck..
•
Rotate the adjusting screw clockwise to increase
the pressure.

•
Rotate the adjusting screw counterclockwise to
decrease the pressure.
