In my area we have guinea grass that grows in clumps that can be up to a couple feet in diameter. Each blade of this grass is about 3/8" diameter and they can grow to 12' tall. I sometimes can wrap a chain with a slip hook around a clump and pull the entire clump out, but not always. We also have a constant problem with weed trees that sprout everywhere due to mynas scattering seeds. When these have a trunk 3-4" diameter I can use the chain to pull them, but smaller than that the trunk will break leaving behind roots that then sprout. I need some kind of claw that can be attached to a chain and will dig into the root system, like a boat's anchor digs into the sea bottom, and then pull out the entire root structure. Ideally there would be 2 claws separated 4 - 6" so it could straddle the small weed tree trunks. It needs to be pretty strong for the load I would put on it. I would pull either with my tractor or using a comealong. It needs to be pullable by the chain because often it is impossible to get the tractor closer than 10 or 15'. I have been unable to find anything for sale, and would prefer not to attempt to construct this myself if something is commercially available at a modest price. Anyone know of such a thing?
