Cutterbar Disc Maintenance; Inspecting The Cutterbar Discs - MacDon R85 Operator's Manual

7.6 Cutterbar Disc Maintenance

Check daily that discs are not damaged by rocks or worn excessively from abrasive working conditions.
They are interchangeable and a disc can be moved to a spindle that rotates in the opposite direction, as long as it
is in a usable condition and the blades are oriented to cut in the correct direction.
The discs are NOT repairable and must be replaced if severely damaged or worn.
If holes appear in a disc, replace the disc immediately. Do NOT attempt to repair the discs. Always use
factory replacement parts.
