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 may be obtained through Sears Parts & Repair or by calling 1-888-331-4569.
