MAINTENANCE
WARNING! When attaching PTO yoke to tractor PTOshaft, it is important that spring-activated locking
collar slides freely and locking balls are seated in groove on PTO shaft. A loose shaft could
slip off and result in personal injury or damage to cutter.
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.
IMPORTANT! 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 gear box bearings. Vibration may also cause structural cracks in cutter housing.
WARNING! 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
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
Figure 5. Always sharpen blades by grinding. 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.
WARNING! Avoid personal injury. Always block the cutter up to prevent if from falling when the blades
and / or carrier are being serviced.
