5. Place two thick blocks under rear left and right
lower edge of the mower deck so the weight of
the deck rests on the blocks.
6. Lower the mower to the 3 inch (76 mm)
height-of-cut position.
7. Loosen the bolts connecting the two chains
and the two rear brackets to the mower
(Figure 52).
8. Adjust the two rear bolts so they are in the
middle of the slot located in the pivot bracket
(Figure 52).
9. Adjust the bolts so the end of the bolt is flush
with the nut. This will allow the bushing to
roll in the slot in the mower deck bracket
(Figure 51).
10. Adjust the discharge side front bolt so it is
in the middle of the slot located in the pivot
bracket (Figure 52).
11. Raise the mower deck and remove the blocks
holding up the mower deck.
12. Adjust the left front bolt in the pivot bracket
so the chain has no slack in it.
13. Inspect the four chains. The chains need to
have tension.
Note:
When properly adjusted, the front
blade tip will be a 1/4 inch (6 mm) lower for
34 inch mowers and 3/16 (4 mm) lower for 40
inch mowers than the rear blade tip. Refer to
Checking for Bent Blades for the procedure to
measure the blade tip height.
