Replacing Pointed Center Guard on Double-Knife Header
Check daily that guards are firmly bolted to the cutterbar, and not worn or broken. Replace as required. A worn or
broken guard can be replaced without removing knife from cutterbar. This procedure applies to the center guard
where the two knives overlap on a double-knife header.
IMPORTANT:
Replace adjacent guards when replacing center guard.
