8. Loosen the jam nut under the rear support arm and
adjust the adjustment bolt to get a measurement of
3-1/8 to 3-1/4 inches (Figure 69).
Note:
It is recommended that both sides of the
mower are adjusted the same distance.
9. Tighten the jam nut under the rear support arm
and tighten the bolt securing the chain to the rear
support arm.
10. Adjust the opposite side if needed.
Adjusting the Front-to-Rear Mower
Pitch
1. Position the right blade front-to-rear (Figure 70).
Figure 70

Measure here from blade
to hard surface
2.
Measure at A and B
2. Measure the right blade at the
A
location, from a
level surface to the cutting edge of the blade tip
(Figure 70).
3. Record this measurement.
4. Measure the right blade at the
B
location, from a
level surface to the cutting edge of the blade tip
(Figure 70).
5. Record this measurement.
6. 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 70). If it is not correct, proceed to the
following steps.
Note:
Both of the front swivels need to be adjusted
the same amount to maintain equal chain tension.
7. Loosen the front swivel jam nuts, at the front of
the right and left swivels, approximately a 1/2 inch
(13 mm) (Figure 69).
8. Adjust the lift nuts on both the left and the right
side of the machine to achieve 1/4 to 3/8 inch
(6 to 10 mm) lower in front at A than in the rear at
B
(Figure 69).
9. Tighten both swivel jam nuts against the front swivel
to lock the height.
10. Check to make sure there is equal tension on the
chains and adjust again if needed.
Adjusting the Compression Spring
1. Raise the mower lift lever to the transport position.
2. Check the distance between the two large washers,
it needs to be 11-1/8 inches (28.2 cm) for 52 inch
mower decks, 10-1/2 inches (26.7 cm) for 60 inch
mower decks or 11–1/2 inches (29.2 cm) for 72 inch
mower decks (Figure 71).

3. Adjust this distance, by loosening the spring jam
nut and turning the nut in front of each spring
(Figure 71). Turning the nut clockwise will shorten
the spring; counter-clockwise will lengthen the
spring.
4. Lock the nut into position by tightening the spring
jam nut (Figure 71).
