4. Turn adjustment cap screw clockwise on low side of
mower pan to raise low side one half the difference in
height.

Mower Pitch and Height
Proper blade pitch is when the blade tip, measured from
the bottom surface (Figure 16), is 1/4" to 3/8" lower at
front of mower pan than when same tip is at rear of
mower pan.
Adjusting front lift link raises or lowers front of mower pan
and changes both cutting height and pitch (Figure 9).
To adjust:
1. Loosen jam nut on front link to allow for movement of
coupling nut.
2. Turn coupling nut clockwise to raise and
counterclockwise to lower front of mower pan.
3. Secure coupling in position by tightening jam nut.
Adjusting rear lift links raises or lowers rear of mower pan
and changes both cutting height and pitch (Figure 9).
To adjust:
1. Loosen both lower jam nuts to allow for movement of
upper jam nuts on lift rods.
2. Turn both upper jam nuts on each lift rod equally to
raise or lower rear of pan.
3. Secure lift rods in position by tightening lower jam
nuts.
If proper pitch cannot be obtained with front and rear lift
links:
1. Loosen nut on carriage bolt and remove cap screw
holding lift strap and adjustment strap together
(Figure 17).
2. Slide lift strap and adjustment strap together to raise,
or apart to lower rear of pan.
3. Select tapped hole in lift strap that provides proper
adjustment, install cap screw in tapped hole and
tighten nut on carriage bolt to secure.
Anti-Scalp Rollers
See figure 1 for Controls and Features.
Secure rollers in middle position for average lawn
mowing.
1. Use lowest roller position when mowing in higher
cutting heights and rough terrain to guard against
most scalping.
2. Use highest roller position when cutting at lowest
cutting height.
For smoothest appearing cut when using frame
suspended models with anti-scalp rollers, keep anti-scalp
rollers adjusted to the minimum 1/2" above flat hard
smooth surface after setting height of cut.
NOTE:
The rollers are intended for anti-scalping, not for
controlling cutting height.
