pins. See Figure 57.
2. The brush guard assembly may now be
removed. See Figure 58.

Sharpening the Blade
1. To properly sharpen the cutting
blades, remove equal amounts of
metal from both ends of the blades
along the cutting edges, parallel to
the trailing edge, at a 25° to 30° angle.
Always grind each cutting blade edge
equally to maintain proper blade
balance. See Figure 52.
2. Test the blade’s balance using a blade
balancer. Grind metal from the heavy side until it balances evenly.
WARNING
A poorly balanced blade will cause excessive vibration, may damage the
tractor and/or result in personal injury.
Changing the Deck Belt and Reinstalling the Deck
CAUTION
The V-belts found on your tractor are specially designed to engage and disengage
safely. A substitute (non-OEM) V-belt can be dangerous by not disengaging
completely. For a proper working tractor, use factory approved belts.
All belts on your tractor are subject to wear and should be replaced if any signs of wear
are present. To change or replace the deck belt on your tractor, proceed as follows:
1. Remove the deck as instructed earlier in this section under Deck Removal.
2. Loosen, but do not remove the hardware on the right and left idler pulley.
NOTE: On some decks it may be necessary to remove the spindle covers to
remove and/or install the new belt. To remove the spindle covers, remove the
screws securing them to the deck.
3. Carefully remove the belt from around the idler pulleys and the spindle pulleys.
4. Route the new belt as shown in the applicable figure on the following pages.
See Figure 53 for 42” decks, Figure 54 for 46” decks and Figure 55 for 50” &
54” decks.
