John Deere 820 (1956-1958)
The John Deere 820 was a utility tractor made from 1956 to 1958. It had a strong 2-cylinder diesel engine that could produce 67 horsepower. This engine was very large for its time, with a displacement of 470.7 cubic inches. The tractor was built to handle tough farm work and came with features like a Category 3 hitch at the back and a power take-off (PTO) that could run at 540 rpm. The 820 was a big tractor, weighing 7,848 pounds and measuring over 11 feet long. It had a 2-wheel drive system and manual steering. The tractor used a transmission with 6 forward gears and 1 reverse gear. It had an open operator station, which was common for tractors of that era. One unique feature was its gasoline pony motor, which helped start the main diesel engine. The 820 also had a large fuel tank that could hold 32.5 gallons of diesel, allowing for long work days without refueling.
