Maintenance

Deck Lift Rod Timing Adjustment

1. Park the machine on a flat, level surface. Disengage the
PTO, engage the parking brake, turn off the engine, and
remove the ignition key. Drive tires must be inflated to
10 psi (0,69 bar); tractor caster tires to 25 psi (1,72 bar);
mower deck caster tires to 25 psi (1,72 bar).
2. To check the deck lift rod timing, set the cutting height
adjustment to 3-1/4" (8,26 cm). Both the front and rear
rod pivots should be straight up and down. See Figure
39.
3. If the front and back rod pivots are straight up and down,
no further adjustment is required. If the front and back
rod pivots are NOT straight up and down, adjustment is
required, continue with Step 4.
4. Block up the mower deck up until all hanger chains are
slack. Refer to Figure 40.
5. See Figure 41. To adjust the lift rod, loosen the jam nut
(B, Figure 41) on the front clevis (C) and then remove
the 1/2" clevis pin fastening the clevis to the lift pivot
arm.
• Turn the clevis CLOCKWISE to cause the rod pivot to
pivot backwards;
• Turn the clevis COUNTER-CLOCKWISE to cause the
rod pivot to pivot forwards.
Reinstall the clevis on the lift pivot arm and secure with
the 1/2" clevis pin previously removed. Tighten the jam
nut against the clevis.
6. Remove the blocks from under the mower deck.
7. Remove the cutting height adjustment pin, extend the
actuator, reinstall the cutting height adjustment pin in the
desired cutting height location and retract the actuator
until contact is made with the cutting height adjustment
pin.

These edges of the
rod pivots should be
