  SECTION 7 MAINTENANCE AND SERVICING 
169000  120  Revision F 
TIP: If trouble is encountered cutting tangled, or 
fine-stemmed material, replace guards with  
stub guards. 
If material is tough to cut, install stub guards with 
top guard and adjuster plate. A stub guard 
conversion kit for the header/mower conditioner 
is available from your Dealer. Refer to Section 
9.5 STUB GUARD CONVERSION KIT. 
7.8.7.2 Replacing Guard  
Check daily that guards are firmly bolted to the 
cutterbar, and are NOT worn or broken. Replace 
as required. A worn or broken guard can be 
replaced without removing knife from cutterbar. 
7.8.7.2.1  Replacing Pointed Guard 
Refer to previous section for standard  
guard replacement. 
The guard near the center of the double knife 
header, where the two knives overlap, requires a 
slightly different replacement procedure. 
IMPORTANT 
Replace adjacent guards when replacing 
center guard. 
a.  Remove two nuts (A) and bolts that attach 
center guard (B) and top guide (C) to cutterbar. 
b. Remove guard and top guide (C), and  
adjuster bar (D). 
IMPORTANT 
Ensure center guard (B) has offset cutting 
surfaces. See illustrations. 
NOTE 
Top guide (C) must accommodate the 
two overlapping knives at center  
guard (B) location on double knife 
header. Ensure replacement is  
correct part. 
IMPORTANT 
Ledger surfaces of center and adjacent 
guards must be vertically aligned to avoid 
interference with knife sections. 
c.  Position replacement center guard (B), adjuster 
bar (D), top guide (C), and install bolts. Do NOT 
tighten fully. 
d. Check and adjust clearance between top  
guide (C) and knife. Refer to Section 7.8.8 Knife 
Hold-Downs.
