MAV™ Straw Chopper Complete Chopper System | John Deere STS

The MAV™ Complete Straw Chopper for the STS combine provides a complete replacement for the factory straw chopper and chaff spreaders.

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.
