Cutting Unit Maintenance

Blade Safety

A worn or damaged blade or bedknife can break, and
a piece could be thrown toward you or bystanders,
resulting in serious personal injury or death.
•
Inspect the blades and bedknives periodically for
excessive wear or damage.
•
Use care when checking the blades. Wear gloves
and use caution when servicing them. Only
replace or backlap the blades and bedknives;
never straighten or weld them.
•
On machines with multiple cutting units, take care
when rotating a cutting unit; it can cause the reels
in the other cutting units to rotate.
Backlapping the Cutting
Units
WARNING
Contact with the cutting units or other moving
parts can result in personal injury.
• Keep fingers, hands, and clothing away
from the cutting units or other moving
parts.
• Never attempt to turn the cutting units by
hand or foot while the engine is running.
Use this process to restore the sharp cutting edges
to reels and bedknives, which are needed for
good-quality grass cutting.
This process removes a small amount of metal to
restore the cutting edges. If the blade edges are
seriously worn or damaged, remove the cutting unit
and have the reels and bedknife ground.
1. Engage the parking brake, lower the cutting
units, shut off the engine, and remove the key.
2. Adjust the reels to the bedknives to obtain light
contact.
3. Apply a coat of medium-grade detergent-based
carborundum paste to the cutting edges of the
reels with a long-handled brush.
