Mower Blade Care
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 1-800-659-5917.
The blades may be removed as follows.
1.
Remove the deck from beneath the riding mower, (refer to Deck Removal on
page 30) 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 43.

When reinstalling the blades, be sure they are installed so that the wind
wings are pointing upward toward the top of deck.
4.
Use a tourque wrench to tighten the blade nuts to 70-90 ft. lbs.
5.
Reinstall the deck (refer to Deck Installation on page 31).

Riding Mower Creeping
1.
Creeping is the slight forward or backward movement of the riding mower
when the engine is running at high idle and the drive control levers are
opened out in the neutral position.
2.
If after operating the riding mower for some time, it begins to creep while in
the neutral position, adjust the transmission control rods as follows.
3.
Place the front of the riding mower against an immovable object (e.g. wall,
post, etc.).
4.
Jack up the rear of the riding mower so that both rear wheels are
approximately one inch of the ground.
5.
With the engine running at high idle and the drive control levers opened out
in the neutral position, and the parking brake disengaged, check the rear
wheels for rotation.
6.
If only one wheel is rotating, locate the transmission control rod beneath the
frame at the front of the rear tire. If both wheels rotate, locate both control
rods. See Figure 44.

7.
Remove the flange lock nut and hex screw securing the transmission control
rod to the transmission control arm. Wheel rotation should stop. If it does
not, call the Craftsman Help Line at 1-800-659-5917.
8.
If the rotation stops, adjust the control rod up or down as necessary to align
with the hole in the transmission control arm. Re-insert the hex nut into the
hole in the control arm and secure with the hex lock nut.
9.
If necessary, repeat the previous two steps to adjust the other transmission
control rod.
10.
Lower the riding mower and remove the jack.
