Sharpening the Blades
WARNING
When sharpening blade, pieces of blade could be
thrown and cause serious injury.
Wear proper eye protection when sharpening blade.
1. Use a file to sharpen the cutting edge at both ends of
the blade (Figure 56).
Note: Maintain the original angle. The blade retains
its balance if the same amount of material is removed
from both cutting edges.

1. Sharpen at original angle
2. Check the balance of the blade by putting it on a blade
balancer (Figure 57).
Note: If the blade stays in a horizontal position, the
blade is balanced and can be used. If the blade is not
balanced, file some metal off the end of the sail area
only (Figure 55). Repeat this procedure until the blade
is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 55).
Important: The curved part of the blade must be
pointing upward toward the inside of the mower to
ensure proper cutting.
2. Install the spring disk and blade bolt (rotating it
clockwise).
Note: The spring disk cone must be installed toward
the bolt head (Figure 55).
3. Torque the blade bolt to 135-150 N-m (100-110 ft-lb).

Mower Deck Leveling

Check to ensure the mower deck is level any time you install
the mower or when you see an uneven cut on your lawn.
The mower deck must be checked for bent blades prior to
leveling; any bent blades must be removed and replaced.
Refer to the, Checking for Bent Blades (page 38), procedure
before continuing.
The mower deck must be leveled side-to-side first then the
front to rear slope can be adjusted.
Requirements:
•
The machine must be on a level surface.
•
All four tires must be properly inflated. Refer to Checking
the Tire Pressure (page 35).
Checking 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 neutral
lock position, stop the engine, remove the key, set 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 58).
Note: If both measurements are not within 5 mm
(3/16 inch), an adjustment is required; continue to the
Leveling procedure.
