MAV™ Straw Chopper Complete Chopper System | Challenger Combines

The MAV™ Complete Straw Chopper provides the replacement of the factory straw chopper and chaff spreader. It cuts extra fine, spreads wider, and allows the spreading straw and chaff.

Complete Straw Chopper for John Deere STS
  • Spread both chaff and straw through the straw chopper
  • Replaces factory straw chopper/chaff spreader
  • Spreads 25' to 45' wide
  • Cuts material finer with the 1" tight knife bar spacing
  • Adjust spreading width quickly with the split tailboard
  • Change from chopping straw to dropping in seconds
  • Reverse blades when initial blade edge is worn
  • Knife bar bank breaks away when needed - minimizing damage
  • Residue is projected farther - minimizing dust around the combine
  • Achieve an even distribution of residue across width of the cutter bar.

The MAV™ Straw Chopper Rotor Upgrade is available for:
