The International Harvester 15-30 is a standard-tread tractor well-known for its substantial size and weight, coming in at an operating weight of 8990 pounds. It features a unique chassis design as a 4x2 2WD, indicative of a simple but robust traction capability. The tractor operates via a straightforward gear transmission with two forward gears and one reverse gear. Powered by a 692.7 cubic-inch, 4-cylinder liquid-cooled engine running on kerosene, the 15-30 is capable of performing agrarian tasks at a rated RPM of 575. The liquid cooling system was sizable for its time, accommodating up to 160 quarts of coolant. With a length of 140.5 inches, a width of 85 inches, and a height of 118 inches, the tractor presents a formidable stance in the field. Though specific functionality details such as the hitch type, power take-off, or hydraulic systems are not fully documented in the data provided, the 15-30 remains an example of early twentieth-century tractor design, focusing on power and basic functionality over the more sophisticated features found in modern machines.
