MAINTENANCE
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.
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.
Replace bent or broken blade with new blades. NEVER ATTEMPT TO STRAIGHTEN OR WELD
ON BLADES SINCE THIS WILL LIKELY CRACK OR OTHERWISE DAMAGE THE BLADE
WITH SUBSEQUENT FAILURE AND POSSIBLE SERIOUS INJURY FROM THROWN BLADES.
