3/4” to 3” Height-of-Cut Range
When the mower height-of-cut is set to the 3/4” to 3”
range the gage wheels contact the ground. There is a
second side-to-side adjustment for this height range.
1.
Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the ignition key to “OFF” to stop the
engine. Remove the key.
2.
Set Dial-a-Height to the middle of the
height-of-cut range; refer to Setting
Height-of-Cut page .
3.
Carefully rotate blade(s) side to side (Fig. 8).
Measure between the outside cutting edges and
the flat surface (Fig. 8). If both measurements
are not within 3/16” (4.762mm), an adjustment
is required.
4.
Raise attachment lift lever to release pressure on
the gage wheels. Remove hairpin cotter and
washer from trunnion (Fig. 10).

Front-to-Rear Blade Slope
Check the front-to-rear blade slope any time you
install the mower. Before checking the slope, set air
pressure in the front and rear tires to 12 psi (.85 kPa).
If the front blade tip is not 0–1/8” (0–3.2 mm) lower
than the rear blade tip, adjust the blade slope using
the following instructions:
1.
Park the machine on a level surface, disengage
the power take off (PTO), set the parking brake,
and turn the ignition key to “OFF” to stop the
engine. Remove the key.
2.
Check and adjust side-to-side blade level if you
have not checked the setting; refer to
Side-to-Side Mower Leveling, page 6.
3.
Adjust the Dial-A-Height knob so the
height-of-cut is in the middle of the range and
lower attachment lift.
4.
Carefully rotate blades so they are facing front
and rear (Fig. 11).
5.
Measure between the tip of the front blade
(Fig. 11). and the tip of the rear blade to the flat
surface. If the front blade tip is not 0–1/8”
(0–3.2 mm) lower than the rear blade tip adjust
front adjustment link.
