4.4 Cutterbar System

Cutterbar (A) is 3.9 m (13 ft.) long. The 3.9 m (13 ft.) cutterbar holds eight discs that rotate to a maximum of 2500 rpm at
full engine speed.

4.4.1 Cutterbar Doors

Two doors with rubber curtains provide access to the cutterbar area, and reduce the risk of objects being ejected. Always
keep doors closed during operation.

Inspecting Cutterbar Doors

The cutterbar doors protect bystanders from flung objects and protect the blades from obstacles. They should be inspected
periodically.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator's seat for any reason.
1. Shut down the engine, and remove the key from the ignition.
2. Ensure that the door operates smoothly and lies flat when it is closed. Adjust the doors if necessary.
