4. To reinstall the blades, reverse the above process and
tighten nut to 70-90 lb. ft.
NOTE: Add a small amount of multi-purpose grease to the
bolt threads to avoid corrosion and galvanic action.
5. Reinstall the deck (refer to Deck Installation on page 27).
WARNING!: Never mow with dull blades. Blades
that are bent should be replaced. The cutting blades
are sharp and can cause severe injury. Wrap the
cutting surface of the blade with a rag to avoid injury.
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 drive belt. (See Replacing the Belt)
3. Remove the blade. (See Mower Blade Care).
NOTE: Take note of the order that the parts composing the
assembly are placed.
4. Using a ⁄” wrench or socket ratchet remove four hex
washer screws securing the spindle assembly to the deck.
