4. Insert the lift lock lever assembly screw into the control
panel hole and secure it with a lock nut. Position the
lift lock lever as shown in Figure 13.
5. Affix the lift lock lever decal to the control panel,
positioning as shown inFigure 13.
6. Secure the control panel to machine with the screws
previously removed.
7. To operate the lift lock lever, rotate it under the front
edge of the lift switch to prevent the switch from being
activated.

Adjusting the Counterbalance
Pressure
No Parts Required
Procedure
For best performance, the cutting unit bounce on uneven
turf is minimal and it does not ride heavily over flat terrain.
If scalping occurs or the cut is uneven from side to side,
there may be too much weight on the deck and the weight
may have to be transferred to the machine: i.e. increased
counterbalance pressure.
By contrast, if too much weight is transferred to the machine,
the deck will bounce excessively and the cut will be uneven.
If the cutting unit does not perform properly, adjust the
counterbalance pressure as follows:
1. Ensure that the parking brake is set, the PTO switch is
in the Off position, and the cutting unit is lowered.

2. Locate the lift manifold on the right side of the
machine.
3. Connect a pressure gauge to the test port at the rear of
the lift manifold (Figure 14).

4. On the front of the lift manifold, remove the cap from
the manifold counterbalance spool (Figure 14).
5. Loosen the jam nut at the bottom of the counterbalance
spool (Figure 14).
6. Start the engine and set the throttle to high idle.
7. Using an Allen wrench, adjust the lift valve spool until
the desired pressure is attained on the gauge. See the
chart below for the recommended pressure setting for
the cutting deck.

8. Stop the engine.
9. Tighten the jam nut on the bottom of the
counterbalance spool. Torque the nut to 13-16 N-m
(10-12 ft.-lb).
10. Remove the pressure gauge from the test port.
