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.
