McCormick-Deering W-40

The McCormick-Deering W-40 is a sturdy tractor built for farm work. It has a gasoline engine made by International Harvester with 6 cylinders. The engine is naturally aspirated, which means it doesn't use a turbocharger. It can hold 48 quarts of coolant to keep the engine cool while working.

This tractor is big and heavy, weighing 6,100 pounds. It's 141.5 inches long, 65.75 inches wide, and 73 inches tall. The W-40 has steel wheels instead of rubber tires, which was common for older tractors. It has 4 forward gears and 1 reverse gear, allowing the farmer to choose the right speed for different jobs. The transmission is unsynchronized, so the driver needs to be careful when changing gears.

The W-40 has some unique features. Its front wheels are 6 inches wide, while the back wheels are wider at 12 inches. This design helps the tractor move well in fields. The engine runs at 1,750 RPM when working hard. While we don't know much about its power take-off (PTO) system, the W-40 was likely a reliable workhorse for farmers in its day.
