Here are the John Deere 80, 820 and 830 twin-cylinder diesel tractors from 1955, 1958 and 1959.
The Model 80 was introduced in 1955, replacing the older Model R. It received new features, such as a larger diesel engine and a different starter, as well as six forward gears. Options included power steering, PTO (also available with active PTO), and remote hydraulics.
The John Deere 820 series was produced between 1956 and 1958, with a total of 7,080 tractors built during this period. The only difference between the 80 and 820 is the introduction of the usual electric start and a larger motor that produces more power.
In 1959, the John Deere 830 was introduced. It retained the same powertrain as the 820. An electric start was offered in place of the gasoline starter for standard Wheatland models. The John Deere 830 became known as the "King of the Twin" because it was the largest John Deere twin ever built and the last to complete one of the best John Deere generations of all time.
