The Model G is a small implement carrier tractor that was made by the Allis-Chalmers Manufacturing Company. At the time of its introduction the Model G was unique for its rear-mounted, Continental N62 engine.[1] It was a four-cylinder engine with a 2+3⁄8 by 3+1⁄2 inches (60 mm × 89 mm) bore and stroke.[2] The Model G was designed for small farms and vegetable gardeners, and a line of implements specifically designed for it, including ploughs, planters, and cultivators. The design of the Model G allowed for a great view of the belly-mounted implements.
