I don't think I would want to use one of these on a vehicles wheel hub.
But something like "highbeam" has, or something similar on the front of the PT, I would give a go at in a heart beat (of course dirtbike racing, police officer, OH journeyman linemen, etc. has made me lead the "exciting" life more than a few times).
I can see the possible danger, but I don't hear or see any stats from many of the people denouncing this little device, that shows it is a proven hazard.
If I was mechanically inclined (and I am not, I can barely spell the word) I would design something for the PT. It looks like it would be a lot cheaper and less work than the standard "log splitters".
Now that I think about it, maybe welding something together that the mower deck motor and coupler could attach to...just a thought.
