Stub Guards – Double Knife
Refer to previous section for typical guard
replacement.
The guard at the center of the double knife
header, where the two sickles overlap, requires a
slightly different replacement procedure.
To replace the center guard or center top guide,
proceed as follows:
a. Remove the two nuts (A) and bolts that attach
guard (B) and top guide (C) and adjuster bar (D)
to cutterbar.
b. Remove guard, poly wear plate (if installed), top
guide (C), and adjuster bar (D).
c. Position poly wear plate (if applicable),
replacement guard (B), adjuster bar (D), top
guide (C), and install bolts but do not tighten.
IMPORTANT
Ensure center guard (B) (right of
cutterbar split) has offset cutting
surfaces. See illustration.
NOTE
Top guide (C), which is an inverted
normal stub guard, must accommodate
the two overlapping knifes at center
guard location on double-knife header.
Ensure replacement is correct part.
d. Check and adjust clearance between hold-down
and sickle. Refer to Section 8.7.7 Sickle Hold-
Downs.
