CAUTION

blades.
CAUTION
Damaged blades may damage the cutterbar,
and result in poor cutting performance.
Replace damaged blades at earliest possible
opportunity.
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
a. Check daily that the cutter blades are securely
attached to the disc.
b. Check blades for cracks or wear beyond safe
operating limits, and distortion.
c. Replace blades immediately if any of these
problems occur.

otherwise the disc may be unbalanced
and damage the cutterbar.
