I just tried out one of the puck style "daplug" pintle locks that one of the lawnsite sponsors sells. I have to say it's a really heavy duty lock and would take quite a bit of time to defeat with normal tools. Has anyone else tried these locks? I have been looking for a lock to help deter someone from hooking up my chipper which I occasionally have to leave on site in rural locations. Up until now, I have been using a gorilla style lock which I now think is flimsy compared to this lock and have not slept well knowing that theft is a big concern out here in boonies. I also wanted something compact that I could keep in my toolbox. In addition to disabling as many of the controls as possible, I now have what I think is a much better way of protecting the lunette eye from hookup and wanted to share it. Any thoughts?
