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.
