Select the proper number of spacers for the height-of-
cut and slide the bolt into the spindle (Fig. 31).
Important
The curved part of the blade must point
upward toward the inside of the mower to ensure proper
cutting.
2.
Install the remaining spacers and secure them with a
thin washer and a nut (Fig. 31).
3.
Torque the blade bolt to 75–80 ft-lb (101–108 N
S
m).
Servicing the Air Cleaner
Service Interval/Specification
Foam Element: Clean and re-oil after every 25 operating
hours.
Paper Element: Replace after every 100 operating hours.
Inspect the foam and paper elements, and replace them if
they are damaged or excessively dirty.
Note:
Service the air cleaner more frequently if operating
conditions are extremely dusty or sandy.
Removing the Foam and Paper Elements
1.
Disengage the power take off (PTO), set the parking
brake, and turn the ignition key to off. Remove the key.
2.
Clean around the air cleaner to prevent dirt from getting
into the engine and causing damage. Unscrew the cover
nut and remove the air cleaner cover (Fig. 34).
3.
Remove the air cleaner assembly (Fig. 34).
4.
Carefully slide the foam element off the paper element
(Fig. 34).

Cleaning the Foam Elements
1.
Wash the foam element in liquid soap and warm water.
When the element is clean, rinse it thoroughly.
2.
Dry the element by squeezing it in a clean cloth.
3.
Put one or two ounces of oil on the element (Fig. 35).
Squeeze the element to distribute the oil.
Note:
Excess oil in the foam element restricts the air flow
through the element and may reach the paper filter and clog
it.
Important
Replace the foam element if it is torn or
worn.
