Received the xerox page from Cumberland. They can be reached at 1 800 334 4640. Their grubbing tongs are $102.45, and come with a "swing aside" brush plate. The ad states " Clear land of brush and trees--roots and all. Guaranteed not to break. Eliminates costly bulldozing. Trees can be pulled from any direction and tongs will not slide or bend. No slipping--the harder you pull, the tighter the tongs grip. Complete with high strength hookup cable. For trees 1 1/2" to 8" in diameter. Weighs 18 pounds. High strength alloy steel construction.....There is a smaller model for 1 1/2' to 5' trees for $93.50. As best as I can describe what the tongs look like would be to say the would look similar to ice tongs, where the tongs would encircle the tree. The cable runs from one handle to the other, and by pulling up on the cable, it closes the tongs around the tree. For a 8" tree, I feel I can remove it with my 4310, so I don't think they would be any use to me. Contact Cumberland, if anyone is interested.
