Installing the Blades
1. Install the blade onto the spindle shaft (Fig. 25).
Important The curved part of the blade must be
pointing upward toward the inside of the mower to ensure
proper cutting.
2. Install the flat washer, lock washer, and blade bolt
(Fig. 25). Torque the blade bolt to 85–110 ft–lb
(115–150 N⋅m).
Servicing the Air Cleaner
Main filter: Check and replace after every 250 operating
hours or more often in dusty conditions.
Inner filter: Replace after every 500 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.
3. Release the latches on the air cleaner and pull the air
cleaner cover off of the air cleaner body (Fig. 28).
4. Clean the inside of the air cleaner cover with
compressed air.
5. Gently slide the main filter out of the air cleaner body
(Fig. 28). Avoid knocking the filter into the side of the
body.
6. Remove the inner 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.
7. Inspect the main 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.

the filter.

Installing the Filters
Important To prevent engine damage, always operate
the engine with both air filters and cover installed.
1. If installing new filters, check each filter for shipping
damage. Do not use a damaged filter.
2. If the safety filter is being replaced, carefully slide it
into the filter body (Fig. 28).
3. Carefully slide the primary filter over the safety filter
(Fig. 28). Ensure that it is fully seated by pushing on the
outer rim of the filter while installing it.
Important Do not press on the soft inside area of the
filter.
4. Install the air cleaner cover with the side indicated as
UP facing up and secure the latches (Fig. 28).
