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.
Use only original equipment blades on this cutter. 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.
BLADE SHARPENING
IMPORTANT! When sharpening blades, grind each blade the same amount to maintain balance. Follow
original sharpening pattern as shown in Figure Mnt-R-0008. Always sharpen blades by grinding. Always
sharpen both blades at same time to maintain balance. The difference in blade weights should not exceed 1
ounce. Unbalanced blades will cause excessive vibration which can damage gear box bearings. Vibration
may also cause structural cracks in cutter housing. DO NOT heat and pound out edge. Do not sharpen blade
to a razor edge, but leave a 1/16" blunt edge. Do not sharpen back side of blade.
Avoid personal injury. Always block the cutter up to prevent if from falling when the blades
and/ or carrier are being serviced.
Replace bent or broken blades with new blades. NEVER ATTEMPT TO STRAIGHTEN,
WELD, OR WELD HARDFACING ON BLADES SINCE THIS WILL LIKELY CRACK OR
OTHERWISE DAMAGE THE BLADE WITH SUBSEQUENT FAILURE AND POSSIBLE
SERIOUS INJURY FROM THROWN BLADES.
BLADE CARRIER REMOVAL/INSTALLATION
Avoid personal injury. Blade and/or blade carrier removal should be done only with the
tractor engine shut off, key removed, in neutral, parking brake on, and PTO disengaged and
the cutter blocked in the raised position.
