4.7.8 Hold-Downs
Hold-downs (also referred to as guides) keep the knife in contact with the guard cutting surface. It is important that
the hold-downs are adjusted properly.
Hold-downs are designed to accommodate specific guard locations and guard types:
•
Center
–
Located at center of cutterbar on double-knife headers. Allows for knife overlap.
•
Standard
–
Used at all other locations.

CAUTION
To avoid bodily injury or death from unexpected startup of machine, always stop engine and remove key
from ignition before leaving operator
’
s seat for any reason.
Check daily that knife hold-downs are set to prevent knife sections from lifting off guards, but still permit the knife to
slide without binding.
