The Acme 12-25 was listed during 1918 and 1919. This wheel-type tractor weighed in at 6,000 pounds. The drivers were 54 inches in diameter with a 12-inch face. A Beaver engine was used, with four cylinders of 4 1/2 inch bore and 6-inch stroke, cast en bloc. The K-W high tension magneto added a touch of elegance. Acme had a unique arrangement for converting back and forth from wheels to tracks. In all other respects, this was an identical model to the wheel-type tractor. In fact, the gearing arrangement was such that identical ground speeds could be maintained whether on wheel or tracks. Unfortunately, Acme marketed an otherwise good machine at a time when enclosed gearing and unit frame designs were stealing the market. As a result, Acme’s efforts at tractor building were cut off far short of success.
