ABSTRACT:
A method and apparatus for removing pieces of wood, such as stumps, from a logging site. In particular, the method entails driving a spike into a given piece of wood, attaching a line to the spike, pulling the piece of wood to a desired area away from the logging site, and then removing the spike from the piece of wood. Also provided is a spike having a head that has a first, broad width at the top of the head, a second, narrow width below the first, broad width, and one or more shafts extending from the second narrow width of the head. Further, the head of the spike has a hole therethrough able to receive a line so that the spike, upon being driven into a chunk of wood, can be pulled to the desired area. Also provided is a spike removal device wherein a forked pressure plate and a forked grabber plate are placed about the second, narrow portion of the spike, then extended away from each other, thereby contacting the broader, first section of the spike and the piece of wood, thereby removing the spike from the wood.
