MAV™ Straw Chopper Rotor Upgrade | John Deere Combines

The MAV™ Straw Chopper rotor upgrade provides a replacement chopper rotor with MAV™ fan shrouds.  It provides fine cut straw and delivers a wider spread.

Straw Chopper Rotor
  • Replaces factory straw chopper rotor only
  • 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
  • Reverse blades when initial blade edge is worn
  • 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:
