These things are cool! I thought they were toys at first but my buddy checked one out. Aparently you drive it over a log and there is a winch cable that drops down to choke the log, pull it up and drive away. 8hp briggs power, super rare evidently. I could really put one of these to work, but only for maybe 2 weekends, and then what do i do with it?
