In auto wrap mode, the baler will automatically enter into and complete the wrapping cycle (after a short delay) following completion of the forming cycle. At the conclusion of the wrapping cycle in the auto wrap mode, the baler will await the operator's signal before ejecting the completed bale.

Abstract: A baler (10) for wrapping a rotating bale (52) of crop material (16) with strands of twine (72) has two twine tubes (68) through which the twine is fed so that ends of the strands dangle from the tubes. A bale density sensor (36) senses bale density and a controller (42) compares the sensed density with a desired density selected by an operator via an operator control panel (34). 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 (60) 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.

Abstract: The baler has a twine monitoring assembly which generates a pulsating signal in response to twine being dispensed during bale wrapping operations. The twine is wrapped around the periphery of a monitor wheel and, during dispensing, the twine rotationally drives the wheel. As the wheel rotates, a magnet affixed to the wheel at a location adjacent the periphery thereof, travels past a stationary, magnetically operated, normally open switch thereby briefly closing the switch and temporarily turning on an indicator light until the magnet moves sufficiently far enough away from the switch. During wrapping of the bale, twine is rapidly dispensed, causing the wheel to rapidly rotate and as a consequence, causing the light to pulsate, indicating to the operator that twine is being dispensed.
