2. Check the balance of the blade by putting it on a blade
balancer (Fig. 38). 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 of the end of
the sail area only (Fig. 36). Repeat this procedure until
the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 36).
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. The spring disk
cone must be installed toward the bolt head (Fig. 36).
Torque the blade bolt to 85–110 ft.-lb.
(115–150 N m).

Servicing the Air Cleaner

Primary Filter: Clean or replace after every 250 operating
hours.
Safety Filter: Replace after every 600 operating hours.
Note: Check the filters more frequently if operating
conditions are extremely dusty or sandy.
Removing the Filters
1. Disengage the PTO, move the motion control levers to
the neutral locked position and set the parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.

4. Release the latches on the air cleaner and pull the air
cleaner cover off of the air cleaner body (Fig. 40).
5. Clean the inside of the air cleaner cover with
compressed air.
6. Gently slide the primary filter out of the air cleaner
body (Fig. 40). Avoid knocking the filter into the side
of the body.
7. Remove the safety filter only if you intend to replace
it.
Important
Never attempt to clean the safety filter. If
the safety filter is dirty, then the primary filter is damaged
and you should replace both filters.
8. Inspect the primary filter for damage by looking into
the filter while shining a bright light on the outside of
the filter. Holes in the filter will appear as bright spots.
If the filter is damaged discard it.
