I have a Cub Cadet Z Force 48 lawn tractor and I recently found a spring that apparently fell off of it while I was mowing. I believe it is the extension spring that attaches to the brake lever, but I am unable to figure out how it should be attached to the tractor. The part number is 732-0963. I'm really not sure exactly where either end should be attached. I've searched extensively online, but haven't had any luck. Any help would be appreciated.
