6.8.1 Replacing Knife Section
Check daily that knife sections are firmly bolted to the knife back and are not worn or broken. Damaged or worn
sections leave behind uncut plants. A worn or broken section can be replaced without removing knife from cutterbar.
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.
