MAINTENANCE

BLADE SHARPENING

Always sharpen both blades at same time to maintain balance. Follow original sharpening pattern as shown in

Figure Mnt-R-0008. 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.

Avoid personal injury. Always block the cutter up to prevent if from falling when the blades

and/or carrier are being serviced.

Do not heat or weld on hard surface blades as this can alter material strength causing

blades to fail in a hazardous manner that could cause injury.

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. 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. Install

blade bolts with partially worn side of bolt or away

from center. Tighten lock nut to 350 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, and PTO disengaged and

the cutter blocked in the raised position.

BLADE CARRIER REMOVAL

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.
