In the past we have discussed tractor security. I made a simple tool to keep honest people honest. It is a pipe with a piece of tubing welded on one end and a flat welded into the other end. This is placed between the rear tires to keep some one from rolling the tractor off. When I made it I was not at the tractor so ended up making it to long. I put a master puck lock on the end that can't be hammered off. The pipe is welded through both sides of the tubing to also stop it from being hammered off. Of course a cutting torch would make short work of it. You can't stop the crooks but at least you can make them work a little. A chain could be run around it and fastened to something else if one wanted to. big dan
