Latest that I read is he has a tracked snow plow with a cab. He got out for some reason and it ran over his leg with severe damage and huge blood loss. There will be further investigation because the Arctic Cat has safety devices to prevent this type of event.
Hmm, well let's hope he survives.
My Kubota tractor has a bunch of safety switches on it. If I dismount with the PTO engaged, it dies. Because it got a hydro transmission, you have to stay seated with it in motion or, it dies. It also has a roll over safety switch, if the tractor gets to a certain angle, it dies. I am certain these switches can go bad but, I believe they would normally fail in the safe mode. One can or could always wire around these switches but, it would be foolish to do so.
Heck, my zero turn mower dies if I get off the seat while the blades are turning. Sure hope he's gonna be alright, he's not only a good actor but a genuinely nice guy (I'm told).

Edited: Fox News just reported that Renner was run over by his snowplow with significant injury to his leg with a lot of blood loss, also chest injuries. His neighbor (a doctor) applied a tourniquet and stayed with him until the EMS helicopter arrived.
Is this 100% accurate? Who knows.........
