Pointed Knife Guards and Hold-Downs
Knife guards assist with aligning the knife bar. Hold-downs hold the sections on the knife bar down against the knife guards
to ensure proper cutting.
The following knife guards and hold-downs are used in pointed guard configurations:
NOTE:
Pointed knife guard configurations require two short knife guards, one at each end of the cutterbar.
NOTE:
A Four-Point Guard kit can be used to replace knife guards. They are ideal for use in rocky conditions, or for harvesting
shatter-prone crops such as lentils. Refer to the header parts catalog for more information.
