I have to thank you for this because I had no idea these even existed.
The PCW4000 portable gas winch has a clutch, line lock, and throttle control assembly that differs from other capstan winches such that the capstan doesn't move until the operator applies tension to the line. IMO, that's a significant safety upgrade.
PCW4000 Gas-Powered Winch
Having become more comfortable with this particular capstan winch, I think it may solve my other problems of access, thorns and hillside working conditions that I would face trying to use a tractor or PT in this area. I was able to find a used pcw4000 at a decent price.
What I need is to learn how to most effectively rig it. What I am wondering is whether I should be using traditional metal snatch blocks and double braided polyester line or if I should be looking more at the Yankum rollers matched with synthetic rope?
I plan to fabricate my own tree mount and a log nose cone from a section of plastic 55 gallon drum rolled into a cone shape.
