Has anyone ever replaced their roller chain on a Gator. I had a big tow chain in the bed of the Gator. My son let his friend drive it around in the snow. He dumped the power bed to get snow out and somehow the tow chain wound up inside the engine compartment , were it got caught in the drive chain and ruined it. Its there a master link? Or do I have to take a whole bunch of stuff apart to replace it?
