I recently picked up a 36' honey bee for my A 86. It was last on a 9790 Massey. My problem is the reel doesn't turn when I engage the header. I already checked to make sure the reel speed is set to manual. I put a single point hookup on the header. Is there a sensor that my pickup has and the draper header doesn't? The pickup header works fine, so I know I have oil flow.
