Cutting Component Inspection
Inspect blades for the following:
Notches and Gouges:
Cause:
Blade contacting foreign objects.
Remedy:
Inspect the area to be mowed and remove foreign objects that could cause damage to the blades.
Excessive Blade Wear:
Cause:
Mower height set too low.
Remedy:
Replace blades more often.
Adjust mower height for mowing conditions to eliminate blade-to-ground contact.
Operating the mower with loose blade hardware will damage the blades and can result in
blade breakage or blade fastener failure. Broken blades or bolts can be thrown out from
under the mower for distances up to 300 feet. When the blades are replaced, the fastening
hardware must be replaced. Check and retighten the blade hardware after the first eight
hours of operation.
Inspect the Blades daily for abnormal wear. REPLACE BLADES IMMEDIATELY if blade has:
•
Become bent or deformed from it’s original shape or
•
Any cracks are visible, or
•
Deep gouges in the blade’s surface are present, or
•
Gouges or chipped areas in the cutting edge are
larger than 1/4” (6.35 mm), or
•
The material on the leading edge has been worn away
by more than 1/4” (6.35 mm)”
Failure to replace abnormally worn blades may lead
to catastrophic failure of the blades and ejection of
the broken part with tremendous force which may
cause serious bodily injury or death.
•
Inspect blades and blade bolts for looseness
and excessive wear. Make sure the mower is
securely blocked up before crawling beneath.
Replace damaged, worn and missing blades as
complete sets to maintain rotary balance during
operation.
•
Ensure carrier hub nut is tightened with the
cotter pin inserted and spread.
