I have a Scott Wyeth Power puller that was made in the 60's! Belonged to my father. It was called a Red Devil. I have 5/16" cable on it and with a snatch block have no trouble pulling the X or my FJ40. However if you want to use a hi-lift without the problem of constant re-rigging then check out this site: Read the whole thing before jumping to the conclusion this is just another "How to use a hi-lift as a winch" article!
