A battery powered cart for pushing a disabled automobile or other large unpowered vehicle comprising a frame having a battery and electric drive motor mounted thereon, an electrical switch means for utilizing current from said battery to activate said electric drive motor, a transversely disposed axle secured to said frame, a drive wheel mounted on each of the outer ends of said axle with each drive wheel having a means for engaging said axle, means engaging the drive shaft of said electric drive motor to said axle whereby rotation of said drive shaft will cause said axle to rotate, a portion of said frame projecting forward of said axle and being formed for contacting and pushing a vehicle, said forwardly projecting portion including at least two upwardly projecting vehicle push bars which are tubular in shape and which are adapted to slidably receive mating tubular members of an accessory attachment whereby said accessory attachment can be attached to the cart by downward insertion of its tubular members over said upwardly projecting push bars, said frame and axle being aranged such that upon operation of the cart said portion of said frame contacting the vehicle will make contact at a point that is higher off the ground than the axis of said axle whereby pushing against said vehicle will cause said frame to rotate backwards about said axle whereby a portion of the weight of said vehicle will be imposed on said cart to enhance the frictional contact of the drive wheels with the ground to provide greater traction for pushing said vehicle, said frame being formed such that the length of the frame from said axle to the vehicle contact point is sufficient to place said contact point above yet relatively close in height to said axle so as to prevent the cart from rotating over backwards about said axle when pushing a vehicle, and a third wheel rotatably fixed to said frame at a point forward of said drive wheels to provide an optional third rolling ground contact point to stabilize the rotation of said frame about said axle.
