MAINTENANCE
BLADE SHARPENING
Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in
FIGURE 19. 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.
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 bearings and break welds and other components. Vibration may also cause structural
cracks in cutter housing.
Never work under equipment supported by a hydraulic device because it may drop if the
control is actuated (even with the engine stopped) or in the event of hose failure, etc.
Always use a secure support for equipment which must be serviced while in the raised
position.
NOTE: Replace Blades in pairs after no more than 1/2" notch wear!
BLADE REMOVAL
To remove blades for sharpening or replacement,
remove the cover plate on deck of cutter near gear
box. Remove lock nut from blade bolt (left hand
threaded bolt). NOTE: Inspect lock nut after
removal and replace if threads are damaged.
Always replace nut when replacing blade bolt.
When installing blades be sure and check blade bolt
pivot diameter for wear. Replace bolt if worn more
than 1/4 inch at any point. See Figure Mnt-R-0014.
Install blade bolts with partially worn side of bolt
either toward or away from center. Tighten lock nut
to 300 ft. lbs.
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, PTO disengaged, and the
cutter blocked in the raised position.
