Leveling the Mower
Side-to-Side
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 in. (76-102 mm) Height-of-Cut
Range
When the mower height-of-cut is set to the 3 to 4 in.
(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. Remove the key.
2. Raise attachment lift lever all the way to the latched
position.
3. Carefully rotate blade(s) side to side (Fig. 12). Measure
between the outside cutting edges and the flat surface
(Fig. 12). If both measurements are not within 3/16 in.
(5 mm), an adjustment is required; refer to steps 4
and 6.
