I'm not a tree pro, but I have wondered about that, especially when trying to drop a tree that has broken and fallen over, but is still connected to the stump. (I have my eye on a nice hickory in that condition.) You don't want it rolling back on you, but you can't always be sure which way the forces are going to roll it once the holding wood is cut.
I was thinking one of those snatch-type towing straps could be used to provide tension to pull it in the direction you want, QUICKLY. Use a bull rope to make sure it can't go the wrong way, and use the strap on the end of a rope with the Maasdam providing the pull to tension the strap.
Crazy? Or just normal tree work dangerous?
