Measure at B and C
2. Measure the right blade at the
B
location, from a
level surface to the cutting edge of the blade tip
(Figure 80).
3. Record this measurement. This measurement needs
to be 3-1/8 to 3-1/4 inches.
4. Position the left blade side-to-side (Figure 80).
5. Measure the left blade at the
C
location (Figure 80),
from a level surface to the cutting edge of the blade
tip.
6. Record this measurement. This measurement needs
to be 3-1/8 to 3-1/4 inches (80 to 83 mm).
7. If the measurements at positions
B
or
C
are not
correct, loosen the bolt attaching the rear chain to
the rear support arm (Figure 81).

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 (80 to 83 mm) (Figure 81).
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 82).

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 82).
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 82).
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 82). 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 81).
