Servicing, page 321.
CAUTION
Wear heavy gloves when working around or handling
knives.
5.8.1 Replacing Knife Section
Inspect the knife sections daily and ensure they are firmly bolted to the knife back and are not worn or damaged
(worn or damaged sections leave behind uncut plants). Worn or damaged sections can be replaced without
removing the knife from the cutterbar.
NOTE:
Coarse serrated sections last longer than fine serrated sections in dirty or sandy conditions. Fine serrated sections
perform better in fine stemmed grasses and plants that contain more fibrous stems.
