Mower Blade Care
WARNING!
Before performing any maintenance,
place the PTO switch in the "OFF" position, 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.
The cutting blades must be kept sharp at all times. Sharpen the
cutting edges of the blades evenly so that the blades remain
balanced and the same angle of sharpness is maintained.
If the cutting edge of a blade has already been sharpened many
times, or if any metal separation is present, it is recommended
that new blades be installed. New blades are available at your
authorized dealer.
The blades may be removed as follows.
1. Remove the deck from beneath the tractor, (refer to Deck
Removal) then gently flip the deck over to expose its
underside.
2. Use a 15⁄16" 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 7-10.

3. When reinstalling the blades, be sure they are installed so that
the wings are pointing upward toward the top of the deck.
