This is odd....I have never seen a mule drive vibrate loose, but it must be happening. If the belt were continually stretching, the mule drive screw would quickly be out of tightening range. Take the screw assembly apart and add a lock nut to the screw. 2 Share this post Link to post Share on other sites
