4. Check the tire pressure of both drive tires. If needed,
adjust to 13 psi (90 kPa)
5. Lower the mower to the 3 inch (76 mm) height-of-cut
position.
Note:
The actual cutting height will not be adjusted
until the deck has been leveled. Refer to Adjusting
Height of Cut.
6. Check the distance between the swivels, measure at
the center of the swivels (center-to-center length)
on the threaded rod. This length needs to be
19-1/2 inches (49.5 cm) for 91 cm mower decks and
17-3/16 inches (43.7 cm) for 102 cm mower decks
(Figure 84).
7. Inspect the four chains. The chains need to have
tension.
8. If either rear chain is loose, the length of the threaded
rod on that side will need to be adjusted to get equal
tension on both rear chains.
9. Use the jam nuts at the front swivel to adjust the
length between front and rear swivels on that side
(Figure 84).
10. If either front chain is loose, loosen the nut on the
upper chain bolt and the jam nut on the adjustment
bolt.
11. Use the adjustment bolt to get equal tension on both
front chains (Figure 84).
12. Tighten the nut on the upper chain bolt and the jam
nut on the adjustment bolt.

Adjusting the Left Side Front-to-Rear
Mower Pitch
1. Position the left blade front-to-rear
2. Measure the left blade at the
A
location, from a
level surface to the cutting edge of the blade tip and
record this measurement (Figure 85).
3. Measure the left blade at the
B
location, from a
level surface to the cutting edge of the blade tip and
record this measurement (Figure 85).
4. The mower blade should be a 1/4 to 3/8 inch (6
to 10 mm) lower at position
A
than at position
B
(Figure 85). If it is not correct, proceed to the
following steps.
5. Loosen the nut on the upper chain bolt and the jam
nut on the adjustment bolt (Figure 84).
