Troubleshooting, Adjustment & Service

DECK LIFT ROD TIMINGADJUSTMENT

1.Park machine on a flat, level surface. Disengage the PTO, stop the engine and engage the parking brake. Rear tires must be inflated to 18 psi (124 kPa); front tires to 25 psi (172 kPa).

2.To check the inner lift rod timing, measure and record the distance between the inner lift pivots and the inner rod pivots. Repeat for other side of unit. See Figure 39.

3.To check the outer lift rod timing, measure and record the distance between the outer lift pivots and the outer rod pivots. Repeat for other side of unit. See Figure 39.

4.If the measurements for the inner rods are equal, and the measurements for the outer rods are equal, no further adjustment is required. If the measure- ments are NOT equal (greater than 1/8” (3,17mm) difference), adjustment is required, continue with Step 5.

5.Lock the deck lift pedal in the TRANSPORT position. Remove the cutting height adjustment pin and lower the mower deck.

6.To ensure that the deck is in the lowest position, push the pedal by hand towards the rear of the unit. Install the cutting height adjustment pin in front of the deck lift pedal arm to prevent the pedal from moving forward. See Figure 40.

7.Block up the mower deck until all hanger chains are slack.

8.Refer to Figure 41. To adjust the inner lift rod, loosen the jam nut on the front ball joint then remove the 1/2” hardware fastening the ball joint the the lift pivot arm. Turn the ball joint clockwise to shorten the dis- tance between the rod pivots or counterclockwise to lengthen the distance between the rod pivots. Reinstall the ball joint on the lift pivot arm and secure with the 1/2” hardware previously removed. Tighten the jam nut against the lift rod.
