Tractor Logging with a Winch IIIB

Skidding out a hitch of seven trees on 4 chokers. So 3 doubles and a single. At the landing the doubles are tougher to get free because of the way I hook them. The chain jams between the two logs when they pull together so they tend to be self locking and don't loosen when the cable goes slack. But in my book that is a good thing - I don't lose them on the trail.
