Installing the Blades
1. Install the blade onto the spindle shaft ( Figure
67 ).
Important:
The curved part of the blade
must be pointing upward toward the inside
of the mower to ensure proper cutting.
2. Install the curved washer (cupped side toward
the blade) and the blade bolt (
Figure 67 ).
3. Torque the blade bolt to 135 to 150 N∙m (100
to 110 ft-lb).

Leveling the Mower Deck
Check to ensure that the mower deck is level any time
you install the mower or when you see an uneven cut
on your lawn.
Check the mower deck for bent blades prior to
leveling, and remove and replace any bent blades;
refer to
Checking for Bent Blades (page 45) before
continuing.
Level the mower deck side-to-side first; then you can
adjust the front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All tires must be properly inflated; refer to Checking
the Tire Pressure (page 43) .
Checking the Side-to-Side Level
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Set the height of cut to 76 mm (3 inches).
4. Carefully rotate the blades side to side.
5. Measure between the outside cutting edges and
the flat surface (
Figure 71 ).
Note:
If both measurements are not within 5
mm (3/16 inch), an adjustment is required; refer
to
Leveling the Mower Deck (page 47) .
