Have you tried this trick to removing jammed up hay in a round baler?

This is a mid-repair, real-time demo of a specific fix: freeing hay jammed in a round baler's belts and rollers using the pressure lock/safety pin found on most balers. The operator shows loosening the pressure gauge setscrew, locking the gate open with the safety pin, and how that slackens belts so you can dig out balled-up hay, then how to reverse the process. Useful for anyone actively running a round baler and dealing with jams, not a buying-decision video.
