A pipe pusher comprises a frame formed to define a passageway therethrough for receiving a length of pipe. Three sets of drive wheels are rotatably coupled to the frame for engaging the length of pipe and pushing the length of pipe through the passageway. Each set of drive wheels is spaced apart axially along the passageway from the other two sets to engage the pipe at separate axial locations along the portion of the length of the pipe inside the passageway. A mechanism is coupled to the three sets of drive wheels for rotating the drive wheels to push the length of pipe through the passageway.
