Chopper (General Information)

causym CAUTION: Do not let anyone stand behind the chopper while it is running. Combine engine must be off, parking brake set and key removed before adjusting chopper.

Before performing service or maintenance on raised chopper, use lift actuator to snap lock-out pins into place.

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

For Chopper High Speed:

  • Grain with tough or green straw
  • Larger platforms

For Chopper Low Speed:

  • Corn
  • Grain with dry straw
  • Smaller platforms

See CHANGING CHOPPER DRIVE SPEEDS later in this section.

NOTE: Less power will be consumed and blade life will be increased with the chopper on low speed.

Start with the chopper on low speed and knife bank out. If cut length is not fine enough the first adjustment should be to slide the knife bank in.

If cut length is still not acceptable then chopper should be placed on high speed and knife bank out.

Final attempt at reducing residue length should be chopper on high speed and knife bank in.
