Side-to-Side Mower Leveling
The mower blades must be level from side to side.
Check the side-to-side level any time you install the
mower or when you see an uneven cut on your lawn.
Before you level the mower, set the air pressure in the
front and rear tires to 20 psi (138 kPa).
3” to 4” (76-102 mm) Height-of-Cut Range
When the mower height-of-cut is set to the 3” to 4”
(76-102 mm) range the mower is suspended from the
tractor.
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. Raise attachment lift lever all the way to the
latched position.
3. Carefully rotate blade(s) side to side (Fig. 13).
Measure between the outside cutting edges and
the flat surface (Fig. 13). If both measurements
are not within 3/16” (5 mm), an adjustment is
required; refer to steps 4 and 6.
