Abstract
A manual automobile pusher comprises a long handle ratchet mechanism mounted on one end of a curved hollow rectangular shaped sleeve, a padded cradle connected to the opposite end of the rectangular shaped sleeve, a curved rack post along which the ratchet mechanism and hollow rectangular shaped sleeve moves, a broad base which is connected to the curved rack post by a pivot pin, and an extensible cross member that is firmly connected to the broad base and the hollow rectangular shaped sleeve. The manual car pusher is capable of developing sufficient horizontal and vertical forces to slowly push an automobile out of a rut in ice, snow or mud, thereby eliminating the waste of gasoline and automobile transmission wear that occurs when a lone driver attempts to free an immobile vehicle by driving it out of a rut.
