Blade Servicing - Alamo Rhino SM72 Operator's Manual

BLADE SERVICING

Inspect blades before each use to determine that they are properly installed and in good condition. Replace
any blade that is bent, excessively nicked, worn, or has any other damage. Small nicks can be ground out
when sharpening.
When sharpening blades, grind each blade the same amount to maintain balance. The
difference in blade weights should not exceed 1 ounce. Unbalanced blades will cause
excessive vibration which can damage spindle bearings. Vibration may also cause structural
cracks in the mower.
Use only original equipment blades on this mower. They are made of special heat-treated
alloy steel. Substitute blades may not meet specifications and may fail in a hazardous
manner that could cause injury.
Inspect Blades daily for abnormal wear. If Blades have a notch worn into the leading edge at
the lower bend more than a 1/2" DEEP (due to running in gravel and/or the ground).
REPLACE BOTH BLADES ON THAT CARRIER IMMEDIATELY. Failure to replace such
abnormally worn blades may lead to catastrophic failure of the blade and ejection of the
broken part with tremendous force which may cause bodily injury or death.
NOTE: Replace Blades in pairs after no more than 1/2" notch wear!
