Regular Maintenance

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.

5.To ensure that the deck is in the lowest position, push 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 or counterclockwise to lengthen the distance between 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.

8.Remove the blocks from the under the mower deck.

9.Remove the cutting height adjustment pin from in front of the deck lift pedal arm. Lift mower deck and reinstall adjustment pin in desired mowing height.
