Cutting Unit Maintenance

Blade Safety

•
Inspect the blade periodically for wear or damage.
•
Use care when checking the blades. Wrap the blades or wear gloves, and use caution when servicing the
blades. Only replace or sharpen the blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1 blade can cause other blades to rotate.

Replacing the Blades

Service Interval: Yearly—Replace the blades.
To maintain balance, replace blades only as an
opposed pair or a whole rotor at a time. Also replace
the bushing, the bolt, and the locknut when you
replace a blade. There are 2 service kits available for
blade replacement; refer to the Parts Catalog.
1. Raise the cutting units and secure them with the
transport latches.
2. Engage the parking brake, shut off the engine,
and remove the key.
3. If you are replacing blades on the center cutting
unit, remove the entire cutting unit unless an
overhead lift is available.
4. Turn the rotor slowly by hand so that each row
of flails are in the desired position and you can
easily access them.
5. Use the rotor locking tool (provided in the
blade-sharpening kit) to lock the rotor.
6. Remove any debris from the bolt head and the
nut and clean the protruding threads with a wire
brush.
7. Mark the position of the bolt head so that you
can replace the bolts from the same side.
8. Holding the blade in a rag or padded glove,
remove the nut, bolt, bushing, and blade

Note:
If needed, apply penetrating oil to the
threads to make the nut easier to remove.
