Cutterbar Disc Maintenance; Direction Of Spindle Rotation - MacDon R85 Operator's Manual

5.4 Cutterbar Disc Maintenance

Perform daily inspections to ensure that cutterbar discs have not suffered damage from rocks, or experienced
excessive wear from abrasive working conditions.
Cutterbar discs are interchangeable and can be moved to a spindle that rotates in the opposite direction as long as
it is in usable condition and the blades are oriented to cut in the correct direction.
The cutterbar discs are NOT repairable and must be replaced if severely damaged or worn.
IMPORTANT:
If holes appear in a cutterbar disc, replace the disc immediately. Do NOT attempt to repair the cutterbar discs.
Always use factory replacement parts.
