MAV™ Straw Chopper Housing and Rotor Upgrade | New Holland Combines

The MAV™ Straw Chopper housing and rotor upgrade provides the replacement of the factory straw chopper housing, rotor, and tailboard. This upgrade cuts extra fine, spreads wider, and spreads straw only - chaff is spread with factory spreaders.

Straw Chopper Walker Housing and Rotor
  • Replaces factory straw chopper housing, rotor, and tailboard only
  • Chaff is not spread with straw
  • 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
