WARNING
Keep hands clear of the area between guards and knife at
all times.
CAUTION
To avoid personal injury, before servicing machine or opening
drive covers, refer to
6.1 Preparing Machine for Servicing, page
343 .
CAUTION
Wear heavy gloves when working around or handling knives.
6.8.1 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.
DANGER
To prevent bodily injury or death from the unexpected start-up of the machine, always stop the engine and remove the
key from the ignition before making adjustments to the machine.
WARNING
Wear heavy gloves when working around or handling knives.
NOTE:
Coarse serrated knife sections last longer than fine serrated sections in dirty or sandy conditions. Fine serrated knife
sections perform better in fine-stemmed grasses and plants that contain more fibrous stems.
1. Shut down the engine, and remove the key from the ignition.
