Troubleshooting, Adjustment & Service
DECK LEVELING 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).
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 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. Refer to Figure 37. To adjust the lift rod timing,
adjust the 5/8” hex nuts on either side of the front
lift pivot until the measurements are equal.
Repeat for other side.
5. Place the deck height adjustment pin in the
4" (10,2 cm) position.
6. Place 2 x 4 blocks under each corner of the
mower deck with the 3-1/2” sides being vertical.
Place a 1/4” (0,64 cm) thick spacer on top of the
rear 2 x 4 blocks. See Figure 38.
7. Adjust the front eyebolts until the chains are tight
and the deck is still resting on the 2 x 4’s. Tighten
jam nuts. See Figure 39.
8. 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 in the slots until the chains are tight and
tighten the nuts. See Figure 39.
9. Remove all 2 x 4 blocks and spacers from under
the mower deck.
