Checking Hold-Down
–
Pointed Knife Guards
The pointed knife guard hold-downs prevent the knife sections on the cutterbar from lifting off of the guards, while still
allowing the knife to slide. The hold-downs will need to be inspected to ensure that there is adequate clearance between
the hold-downs and knife sections.
This procedure is for standard hold-downs. To check the center hold-down on double-knife headers, refer to
Pointed Knife Guards, page 326
.
