Aultman & Taylor 15-30

The Aultman & Taylor 15-30 is a classic 2WD tractor from the early days of mechanized farming. It has a simple design with a 4x2 chassis and steel wheels instead of rubber tires. The tractor is quite large, measuring 176 inches long and 104 inches tall, with a heavy operating weight of 8,240 pounds.

This tractor is powered by a Climax gasoline engine with 4 cylinders. The engine is liquid-cooled and naturally-aspirated, with a displacement of 510.5 cubic inches. It has a bore of 5 inches and a stroke of 6.5 inches. The engine runs at a steady 900 RPM, which was typical for tractors of its time. The 15-30 has a basic manual transmission with just one forward and one reverse gear, making it simple to operate but limiting its speed options.
