Chopper (General Information)

CAUTION: Do not let anyone stand behind chopper while it is running. Shut OFF engine, set parking brake and remove key before adjusting chopper.

Normal use wears the bottom of chopper fins to a sharp edge.

The fine cut chopper cuts the straw discharged from the separator when the chop to drop door is closed. See Residue Management Setup in CommandCenter Display Screens section for changing chop to drop door position.

The chop to drop door can also be set to drop the straw discharged from the separator into a windrow behind the machine, when the door is opened.

Advanced PowerCast Tailboard is used to distribute the chaff material from the cleaning shoe to the width of the header when the chop to drop door is opened.

For Chopper High Speed:

• Grain

For Chopper Low Speed:

• Corn

To change chopper to high speed or low speed, see Chopper Drive Speeds—Changing later in this section.

Start with knifebank in fully disengaged position. If better cut quality is desired, adjust knifebank to fully engaged position, see Chopper Stationary Knifebank—Adjusting later in this section.
