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.
- 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
