Installing the Blades
1. Install the blade onto the spindle shaft ( Figure 65 ).
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 65 ).
3. Torque the blade bolt to 135 to 150 N∙m (100 to 110

Leveling the Mower Deck
Ensure that the mower deck is level any time you install the
mower deck or when you see an uneven cut on your lawn.
Check the mower deck for bent blades prior to leveling;
remove and replace any bent blades; refer to
Checking for
Bent Blades (page 43) before continuing.
Level the mower deck side-to-side before adjusting the
front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All 4 tires must be properly inflated; refer to Checking
the Tire Pressure (page 42) .
Checking the Side-to-Side Level
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.
1. Park the machine on a level surface and disengage the
blade-control switch.
2. Move the motion-control levers outward to the

position, shut off the engine, remove
the key, engage the parking brake, and wait for all
moving parts to stop before leaving the operating
position.
3. Carefully rotate the blades side to side.
4. Measure between the outside cutting edges and the flat
surface (
Figure 69 ).
Note:
If both measurements are not within 5 mm
(3/16 inch), an adjustment is required; refer to Leveling
the Mower Deck (page 46) .
