A pipe pulling device and related methods for removal of an existing old length of pipe and replacement of the old pipe with a length of new, replacement pipe. The pipe pulling device includes a housing, a drive assembly mounted to the housing, and a spool assembly mounted to the housing and operably coupled to the drive assembly. The pipe pulling device can also include a cable attachment mechanism that secures a cable that extends through the old pipe to the spool assembly. The drive assembly operates to rotate a portion of the spool assembly thereby wrapping the old pipe and cable about the spool assembly. An end of the new, replacement pipe can be secured to an opposite end of the cable, wherein the new, replacement pipe is drawn into a cavity vacated by the old pipe as the old pipe is being withdrawn and wrapped about the spool assembly.
