Flail Axe Blades Inspection
Inspect the Blades daily for abnormal wear. REPLACE ALL BLADES on the carrier
IMMEDIATELY if any blades have:
Become bent or deformed from its original shape, or
Oval shape wear inside the blade bolt hole, 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”(8mm), or
The material on the leading edge has been worn away by more than 1/4”(8mm)
Failure to replace worn or damaged 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.
Always replace blades in sets
Blades that are damaged may indicate severe service or abuse. If one blade is worn or damaged
other blades on the same shaft will have been subjected to the same severe service or abuse.
The Flail Axe rotor turns at speeds exceeding 2000 RPM and is dynamically balanced at the fac-
tory. Differences in blade weight between used blades with loss of material from gouges or wear
as compared to new blades can cause severe vibration and damage to the Flail Axe rotor. Always
replace blades as complete sets.
Use only genuine Rhino replacement blades, blade bolts and fasteners. Other blades and
bolts may not meet the requirements of Rhino and fail during operation resulting in part
failing and being thrown out from under the mower.
Never attempt to sharpen blades.
