A mechanical repair is always possible, i.e., a metal patch can be applied to cover the crack and held in place against a gasket interposed between the plate and the cylinder jacket by small machine screws tapped into the iron. If the crack is of some length it may be repaired by the following method: On the line of the fracture, drill signed; the form at B is the adaptable type for other cars as well as the Ford. It is claimed by the manufacturer that this device can be attached in from fifteen to twenty minutes, ready for work in the field. The various features include an auxiliary cooling system, consisting of a centrifugal pump and a specially designed fan to aid in keeping the power unit cool when working under severe conditions. A device for attachment to the carbureter to prevent dust from entering the engine also is supplied. In mounting the attachment the rear wheels of the motor car are removed and the two driving pinions which mesh with the bull gear on the tractor wheels are attached. All implements are pulled by the attachment itself, thus relieving the chassis of the motor car as much as possible from the strain of the work. The gear reduction is eleven to one. Traction is secured by the semi-concave creepers shown in the illustration. For sandy soil special ten-inch angle creepers are supplied. The two side channels are attached to t...
