Patent ID: 8671834

Claim:
A combination of a twine tensioner arm and arm position sensor arrangement comprising: said twine tensioner arm having front and rear ends and being mounted to a frame at a front end region establishing a connection permitting said tensioner arm to be moved between upper and lower extreme positions; said tensioner arm being biased to said upper extreme position and having a twine guide at its rear end for being engaged by a twine strand, which, when tensioned during bale formation, moves said tensioner arm toward said lower extreme position; said arm position sensor arrangement including a rotary potentiometer having a rotatable sensing shaft, a follower arm having a first end coupled to said rotatable sensing shaft and having a separate end located in a path of movement of the twine tensioner arm for being engaged by, and moved together with, the tensioner arm as it moves between said upper and lower extreme positions, with the potentiometer generating an electrical signal representative of the position of the tensioner arm at any given time.
