Replacing the Blades
Before performing any maintenance, disengage the PTO, engage the
parking brake lever, turn the ignition key to the "OFF" position and remove
the key from the switch. Protect your hands by using heavy gloves when
handling the blades. When servicing the mower deck, be careful not to cut
yourself on the sharpened blades.
TO REMOVE THE BLADES:
1. Remove the deck as instructed in the Deck Removal section.
2. Jack up the front of the mowing deck about one foot and block it in that position.
3. Wrap a rag around one end of the blade (a) and grasp it to prevent it from
turning, or secure the blade (a) by placing a block of wood (b) between the blade
(a) and the deck housing (c) (Figure 43).

TO REINSTALL THE BLADES

"Bottom", "Grass Side" or with a part number stamped facing the ground when
the deck is reinstalled on the mower and in the operating position.
2. Carefully place the flat washer on the spindle shaft. Be sure that the splines at the
base of the spindle shaft threads line up with the washer splines (Figure 45).
3. Secure the blade from turning clockwise when reinstalling the flange lock nut
(the opposite direction of blade removal).
4. Install the flange lock nut onto the spindle shaft over the blade and flat washer.

SHARPENING THE BLADES
1. Remove the blades. See Replacing the Blades.
2. Clean any debris from the blades. Keep blades sharp and free of build up at
all times.
3. 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°-30° angle. Always grind each cutting blade edge equally to maintain proper
blade balance (Figure 46).
