Our nieghbors have 3-970's last year and part way though harvest they put a redacopp chopper on one of the combines.The new holland choppers was not spreading very far at all.The redacopp chopper was spreading 30 feet plus.That made our choice easy,we odered our Cr-970 without a chopper and getting our dealer to put a redacopp chopper on which will spread chaff also.Which was another complaint also.
