4.4.5 Cutterblades

Each disc has two cutterblades (A) attached at opposite
ends that are free to rotate horizontally on a specially
designed shoulder bolt.
The blade (A) has two cutting edges and can be flipped
over so that the blade does not need replacing as often.
The blades are NOT repairable and must be replaced if
severely worn or damaged.
IMPORTANT:
Always use factory replacement parts.
