4.1.1 Blower Housing/Impeller:
Inspect for wear or damage daily. Replace or repair worn parts as needed.
Note: When mowing in areas with sandy soil, use low lift blades on the
cutting deck and higher cutting heights to minimize wear on the blower
components.
4.1.2 Idler Bushings:
Lubricate with 1-2 pumps of SAE No. 2 multi-purpose grease.
4.1.3 Belts:
a) Inspect the belt for damage or wear. Replace the belt with one of the following.
b) Inspect the belt position on the idler arm.
The idler arm may become bent during use or transport. A bent idler arm
could cause the belt to jump off of the idler and be damaged.
1) Make sure the belt cover is installed and run the blower for one to two
minutes.
2) Shut off the deck drive, stop engine , wait for all moving parts to stop
and remove key. Engage parking brake. Remove the belt cover and
check to make sure that the belt is riding near the center of the flat idler on
the idler arm.
3) If the belt is not riding near the center of the idler, remove the blower, and
bend the idler arm slightly.
NOTE: Idler still needs to clear the deck stiffener during operation.
4) Reinstall the blower and belt cover and repeat steps 1-3 until the belt is
positioned near the center of the idler.
