MAINTENANCE

REPLACEMENT OF ROTARY DISK

Failure to follow the following warnings and instructions may result in serious injury or damage to the equipment or property!

1 – The bolts that attach the disk to the spindle must be grade 8. These 5/8 inch bolts are to be torqued to 204 dry or 184 oiled ft. lbs.

2 – A thread locking agent may be applied to threads of all mounting bolts before they are installed.

3 – Disks must be inspected daily for hairline cracks between spindle mounting bolts or around the knife mounting bolts. These cracks indicate metal fatigue caused by severe abuse. If cracks are present the disk must be replaced.

4 – Inspect the disk mounting bolts daily when checking tightness of knife mounting bolts. If a disk mounting bolt is loose, it must be removed, threads cleaned, fresh thread locking agent applied, and tightened to proper torque value.

5 – If a knife mounting bolt is loose, the self locking nut must be replaced as a safety precaution. Install bolts through knife and disk from bottom side of disk. Install self locking nuts and torque them to 1070 dry or 800 oiled ft. lbs. It is then recommended that the head of the knife mounting bolt be struck sharply with a hammer and self locking nuts retorqued to 1070 dry or 800 oiled ft. lbs.

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. 4 – Apply loctite “271” to threads.

5 – Torque nut to 176 ft lbs. Knife must swing freely.

DO NOT re-use the locking hex nuts for mounting the knives. If hex nut become loose, or require removal for knife replacement or any other reason, they must be discarded and replaced with new nuts.
