Troubleshooting, Adjustment & Service
DECK LIFT ROD TIMING
ADJUSTMENT
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 15 psi (1,03
bar); front tires to 25 psi (1,72 bar).
Troubleshooting
2.To check the deck lift rod timing, measure and record the distance between the lift pivots and the rod pivots. Repeat for other side of unit. See Figure 39.
3.If the measurements are equal, skip to Step 5. If the measurements are NOT equal (greater than 1/8” (3,17mm) 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” (7.6cm) position to hold in place. See Figure 40.
6.Block up the mower deck until all hanger chains are slack. See Figure 41.
7.Refer to Figure 42. 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 distance 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.
8.Remove blocks from under the mower deck.
9.Remove the 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.
