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 40 psi (2,76 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 36.

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 4-1/2” (11,47 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 38.

7. See Figure 37. 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 piv ts

 

 

 

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.

4. Adjust the front eyebolts until the chains are tight and the deck is still resting on the 2 x 4 blocks. Tighten the jam nuts. See Figure 39.

5. Loosen the nuts and allow the rear of the deck to rest on

 

the 2 x 4’s and 1/4” spacers. Slide the chains down in

 

the slots until the chains are tight and tighten the nuts.
