Deck 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. Rear tires must be inflated to
15 psi (1,03 bar); front tires to 25 psi (1,72 bar).
2. To check the lift rod timing, measure and record the
distance between the lift pivots and the rod pivots.
Repeat for other side of unit. See Figure 38.
3. If the measurements for the rods are equal, no further
adjustment is required. If the measurements are
NOT equal (greater than 1/8” (3,17 mm) difference),
adjustment is required continue with Step 4.
4. Lock the deck lift pedal in the 5” (12,7 cm) position.
Remove the cutting height adjustment pin and lower the
mower deck.

the pedal by hand towards the rear of the unit and install
the height adjustment pin in the 3” (7,6 cm) position to
hold in place.
6. Block up the mower deck until all hanger chains are
slack. Refer to Figure 40.
7. See Figure 39. To adjust the lift rod, loosen the jam
nut on the front clevis then remove the 1/2” clevis pin
fastening the clevis to the lift pivot arm. Turn the clevis
clockwise to shorten the distance between the rod pivots

the rod pivots. 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.
