Minneapolis Threshing Machine Company 40-80

The Minneapolis 40-80 is a standard-tread tractor that was manufactured by the Minneapolis Threshing Machine Company. It features a 4x2 2WD chassis and is steered manually. The tractor is equipped with a rudimentary 2-speed gear transmission system, offering 2 forward and presumably 1 reverse gear, indicative of the machinery from its era. Underneath the hood, the 40-80 houses a 4-cylinder engine fueled by kerosene with a sizable displacement of 1486.2 cubic inches. Though the engine's horsepower rating is not specified, it operated at a rated RPM of 500, which combined with the tractor's weight of 22,500 lbs, suggests this machine was designed for heavy-duty, low-speed operations such as threshing. The tractor rolls on large steel wheels, with especially wide rear tires measuring 85 inches in diameter and 30 inches wide, which would have helped in controlling slippage and distributing the machine's substantial weight in work fields. Given its physical dimensions - a length of 206 inches, a width of 108 inches, and a height of 122 inches - the Minneapolis 40-80 was large for its time and built for intense tasks.
