MAINTENANCE
Remove cotter pin and loosen slotted nut on gearbox shaft. Loosen but do not remove the nut until the blade
carrier is loosened. Use a suitable 2 jaw gear puller to pull carrier off tapered gearbox shaft. If gear puller is not
available use long bar inserted through blade bolt access hole with end against rotor bar. Strike opposite end of
bar with sledge hammer. Rotate blade carrier 180 degrees and repeat process until carrier breaks loose.
BLADE CARRIER REMOVAL
BLADE SHARPENING
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 diference in
blade weights should not exceed 1 ounce. Unbalanced blades will cause excessive vibration
which can damage gearbox 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 it from falling when the blades
and/ or carrier are being serviced.
