The compact pulling apparatus includes a watertight elongated housing extending along a longitudinal axis and a track disposed around the housing along its longitudinal axis. The track enables the apparatus to move when rotatably driven around the housing. Depending on the implementation, the apparatus can include a generator/motor to selectively produce electricity which can power external equipment and rotatably drive the track, and/or a fuel-power engine. The apparatus further includes a power train assembly by which the rotating output power is trans...
