Blade Maintenance

Blade Safety

DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown at you or bystanders,
resulting in serious personal injury or death.
Trying to repair a damaged blade may result in
discontinued safety certification of the product.
• Inspect the blade periodically for wear or
damage.
• Never try to straighten a blade that is bent or
weld a broken or cracked blade.
• Replace a worn or damaged blade.
•
Use care when checking the blades. Wrap the blades or
wear gloves, and use caution when servicing the blades.
Only replace the blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1 blade
can cause other blades to rotate.

Checking for a Bent Blade

After striking a foreign object, inspect the machine for
damage and make repairs before restarting and operating the
equipment. Torque all the spindle-pulley nuts to 176 to 203
N·m (130 to 150 ft-lb).
1. Position the machine on a level surface.
2. Raise the mower deck, engage the parking brake, put
the traction pedal in N
PTO switch is in the O
and remove the ignition key.
3. Block the mower deck to prevent it from accidentally
falling.
4. Rotate the blade until the ends face forward and
backward, and measure from the inside of the mower
deck to the cutting edge at the front of the blade
(Figure 98).
Note: Record this dimension.
5. Rotate the opposite end of the blade forward and
measure between the mower deck and cutting edge of
the blade at the same position as in step 4.
