McCormick-Deering WD-40

The McCormick-Deering WD-40 is a powerful diesel tractor built for tough farm work. It has a strong 4-cylinder engine made by International Harvester. This engine is liquid-cooled and can produce up to 48.79 horsepower. The tractor has a 3-speed gear transmission with one reverse gear, giving farmers good control in the fields.

One unique feature of the WD-40 is its steel wheels with spade lug extensions. These help the tractor grip the soil better. The tractor is quite large, measuring 141.5 inches long, 65.5 inches wide, and 67 inches tall. It's also heavy, weighing 8,450 pounds. This size and weight make it stable for big jobs. The WD-40 has a hand-cranked gasoline ignition to start it up, which was common for tractors of its time. It also has an oil bath air cleaner to keep the engine running smoothly in dusty conditions.
