Personally, I've considered redirecting the puller back to the stump so I can cut/ wedge/ pull things myself. Who's better at it all, me or the groundman?
I can't believe I never thought of doing that. I work alone, and it's often a long walk around the danger zone to go from the tree I'm cutting to the rope puller to add some tension. Duh! "Work smarter, not harder". That also means I could leave the redirect within the danger zone--less than half the distance from the tree to where I've been setting up the rope puller.
