ABSTRACT:
According to the invention there is provided a tree remover which has a relatively long lever in the form of a beam or rod, and has a hole near one end of the lever. A chain having a hook at each end is threaded through the hole. One of the hooks, the slip hook, is looped around the tree trunk or the bottom part of the bush in one or two turns of the chain, and the lever is placed with the end opposite the hole against the ground a given short distance from the root of the tree or bush. The other end of the chain is then locked with the grab hook against the lever, and a substantially horizontal force is applied to the lever. The horizontal force is converted to a significantly greater, substantially vertical, leveraged force for pulling the tree or bush upward and out of the ground.
