Line up the hole in the center of the blade with the s-shaped retainer at the bottom of the spindle assembly and slide the blade into place. 3. Place a block of wood between the deck housing baffle and the cutting blade to act as a stabilizer. See Figure 47. 4. Thread on the hex flange nut to secure the blade to the spindle assembly. 5. Use a torque wrench to tighten the blade spindle hex flange nut to 70-90 ft-lbs (94.9-122 N-m). NOTE: When replacing or reinstalling the blade, be sure to install the blade with the side of the blade marked ''Bottom'' (or with a part number stamped in it) facing the ground. 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 51. 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.

Route the new belt as shown in the applicable figure below. See Figure 52 for 42" decks, Figure 53 for 46" decks and Figure 54 for 50" & 54" decks. 42" Decks Figure 51 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 & 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 properly working tractor, use factory approved belts. 33 Figure 52 46" Decks Figure 53 50" & 54" Decks Figure 54
