Sharpening the Blades
1. Remove the deck from beneath the tractor, (refer to Deck
Removal on page 26) then gently flip the deck over to
expose its underside.
1. Clean any debris from the blades. Keep blades sharp and
free of build up at all times.
2. Sharpen blades evenly at the original 30° angle to maintain
balanced cutting blades. Do not sharpen the underside of
the blades. Use a electric blade sharpener, a conventional
electric grinder or a hand file to sharpen the blades.
3. Replace any blade with severe nicks or dents that cannot
be removed by filing.
4. Check the balance of the blade after sharpening by placing
it on a blade balancer. Do not use unbalanced blades.
5. If the blade dips on one end, file stock off of the cutting
surface on that end.
NOTE: Blades that cannot be easily balanced — REPLACE.
Changing the Spindle Assembly
1. Remove the deck from beneath the tractor, (refer to Deck
Removal on page 26).
2. Remove the hex washer screws securing the belt covers
to the deck and remove the belt from the spindle pulleys.
Refer to Figure 7-13.
1. Remove the drive belt. (See Replacing the Belt)
2. Remove the blade. (See Mower Blade Care).
3. Use a 3⁄4" wrench to hold the hex nut on top of the spindle
assembly when loosening the hex nut securing the blade.
A block of wood may be placed between the deck housing
and the cutting edge of the blade to help in breaking loose
the hex nut securing the blade. See Figure 7-14.
