The John Deere 600 tractor was first released in 1960 and was produced until 1964. This was the first of the John Deere row crop tractors to feature a 4-wheel drive system, allowing it to handle heavier loads and work in more challenging terrain. It also featured a two-cylinder engine that delivered an impressive 40 horsepower. With a rear lift capacity of 2,500 lbs, it was well suited for field work and light hauling. Today, the John Deere 600 is still a popular choice for hobby farmers and collectors alike and continues to be a reliable workhorse.
