I used them to pull pallets of pellets from a trailer. It used to take an hour and a half to wrap the half strap around the floor and it separated the pallet. It's easy to get addicted to them. I used an alligator's jaw, also a great invention, to attach it to a steel support and just pull it back. When I ordered it I saw someone say they used it to uproot bushes, I tried it too, it works great, pulls the roots right out of the ground. I bought a used one, it looked brand new to me, I saved $30.
