Abstract
A pipe puller system and methods of pipe extraction are shown. In one example a pipe to be replaced is pulled by attaching a pulling force to multiple locations along a length of the pipe. In one example pulling forces can be varied between different attachment locations to better control or eliminate tearing of the pipe. In one example, a pipe loosening device may be used prior to pulling the pipe from the ground.
