MAV™ Straw Chopper Rotor and Floor Upgrade | John Deere Combines

The MAV™ Straw Chopper rotor and floor upgrade provides the replacement of the chopper rotor, floor and knife bar. It provides extra fine cut straw and delivers wider straw spreading.

Straw Chopper Rotor and Floor
  • Replaces factory straw chopper rotor, floor and stationary knife bar
  • Factory chaff spreading system remains in use
  • Chaff is spread with straw on STS models
  • Spreads 25' to 45' wide with use of 12 vane tailboard
  • Cuts material finer with the 1" tight knife bar spacing
  • 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
