One of the answers to the demand for a military tractor that can “take it” under all sorts of road conditions, is a six-and-one-half ton, four-wheel drive vehicle propelled by a seventy-five-horse- power six-cylinder engine, developed by Minneapolis-Moline power implement company. With a five-ton 1P,nrmw, such as a 155-mm. Rowitzer, its top road speed is forty t6 fifty miles an hour, and it can haul its burden up a forty-per-cent incline. Air brakes are operated by foot pedal, and a hand brake lever enables the operator to brake or lock either rear wheel. A front rollerbumper twelve inches in diameter helps ease the way over obstructions and across ditches. In tests the tractor smashed a path through a grove of trees up to three inches thick. It has a forty-inch fording depth and can tilt sidewise to fifty-eight degrees without toppling.
