Replacing Pointed Guards on a Double Knife Header

WARNING
To avoid bodily injury from fall of raised reel, always
engage reel safety props before going under raised
reel for any reason.
Refer to Replacing Pointed Guards on a Single Knife
Header, page 145 for typical guard replacement.
The guard near the center of the double knife header
(where the two knives overlap) requires a slightly different
replacement procedure.

a double knife header, follow these steps:
1. Remove two nuts (B) and bolts that attach guard (A)
and top guide (C) to cutterbar.
2. Remove guard, poly wear plate (if installed), top
guide (C), and adjuster bar (D).
