50” FLAIL KNIFE BLADE REPLACEMENT

1. If knives are damaged or badly worn, they will need to be replaced as a set. Replacing a single knife

can cause severe vibration and possible damage to the mower. The knife should not be welded on for

any reason.

2. Always replace the knife bolts when replacing the knives. DO NOT REUSE THE KNIFE BOLTS OR

NUTS.

3. Assemble knives, bushings, bolts and nuts as shown in part section of the manual.

4. Install the locking hex nut so that the flat face of the nut is towards the knife.

5. Apply Loctite® “271” or equivalent to threads.

6. Torque nut to 52 ft. lbs. Knife must swing freely.

Inspect Blade Bolts daily for wear or damage as follows:

Inspect the Blade Bolt daily for abnormal wear. REPLACE ALL BLADE BOLTS on the

carrier IMMEDIATELY if any bolts have:

• Visible cracks or

• If the blade bolt is worn or any recessed area is visible on the bolt, or

• If Blade Bolt has gouges or chipped areas. or

• If Bushing fits loose in the Rotor Shaft.

Failure to replace abnormally worn bolts or bushings may lead to catastrophic failure of the blades and

ejection of the broken part which may cause serious bodily injury or death.

Always replace Blade Bolts with new bolts and new bushings whenever replacing the Blades. To tighten bolts

and nuts, first apply thread lock to nut. Make sure to tighten bolts and nuts just enough to allow the blades to

swing freely, and not bend the cuttershaft lugs. If cuttershaft lugs are bent together because of over tightening

the blades will not swing freely. OPS-U-0043
