MAINTENANCE

Inspect Blades daily for normal wear. If Blades have a notch worn into the leading worn into the leading edge at the lower bend more than 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.

MAINTENANCE

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 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.
