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
22.
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 23.
5. See Figure 24. To adjust the lift rod, loosen the jam nut
(
B, Figure 24
) 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. Extend the actuator until the pressure is removed from
the cutting height adjustment pin. Position 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. Continue to
retract the actuator until the back end of the deck lift
shaft bolt (
D, Figure 21
) is 1/2” (1,27 cm) from the end
of the slot in the actuator link bar (
E
).
NOTE: The actuator must be positioned correctly before
attempting to activate the PTO clutch. If the actuator is not
positioned as described in the above step the mower’s safety
interlock system will cause the engine to shut off.
