Abstract
A harvesting reel is rotatably mounted on left and right saddles. The saddles are slidably positioned on fore/aft extending arms. A fore/aft position sensor is located between one of the fore/aft extending arms and the respective saddle. The fore/aft extending arm is provided with a slot that extends along the arm at an angle thereto. A sensing finger engages the slot and is coupled to a potentiometer by a sensing arm. As the fore/aft position of the reel changes, the relative position of the sensing finger changes creating a changing electrical output from the potentiometer. The resulting potentiometer voltage represents a fore/aft position signal that is directed to a controller.
