Abstract
A baler ( ) for wrapping a rotating bale ( ) of crop material ( ) with strands of twine ( ) has two twine tubes ( ) through which the twine is fed so that ends of the strands dangle from the tubes. A bale density sensor ( ) senses bale density and a controller ( ) compares the sensed density with a desired density selected by an operator via an operator control panel ( ). When the sensed density reaches about half the desired density the twine tubes are moved to a twine insert position so that the ends of the strands dangle adjacent the rotating bale. When a full bale has been formed, the controller automatically actuates a duckbill ( ) to push the ends of the strands toward the bale where they are caught up in the crop material. If either strand is not caught up in the rotating bale, a new wrap cycle is automatically initiated. The twine tubes are moved to a twine cut position, the twine is cut, the twine tubes returned to the twine insert position, and the duckbill is again actuated to push the strand ends toward the bale.
