Mower Blade Care
WARNING! 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.
 Remove the deck from beneath the tractor, (refer to Deck
Removal on page 26) then gently flip the deck over to
expose its underside.
