MAV™ Straw Chopper Housing and Rotor Upgrade | John Deere Walker

The MAV™ Straw Chopper housing upgrade for Walker Combines provides the replacement of the factory straw chopper housing, rotor, and tailboard. This upgrade has extra fine cut & MAV™ technology allowing a wider spread.  Housing upgrades replace the factory chopper 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
  • Spreads 25' to 45' wide
  • Cuts material finer with the 1" tight knife bar spacing
  • Adjust spreading width quickly with the split tailboard
  • 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
  • Chaff is not spread with straw
