The 4010 was the predecessor to the John Deere 4020 which is widely regarded as the most popular tractor ever produced by John Deere and perhaps any other tractor manufacturer in the United States. The 4010 was rated at 80 horsepower in 1960, but tested at 84 horsepower during Nebraska field testing trials making it one of the most powerful two wheel drive farm tractors at that time. The '10' series tractors were introduced to John Deere dealers in dramatic fashion on Augwhen dealers from around the world were invited to Dallas, Texas where the entire new series was debuted at the Dallas Memorial Auditorium. The 4010 was the primary attraction of the new “10” series known as the “New Generation” or “New Generation of Power” which consisted of four and six-cylinder tractors first introduced in 1959 to replace the two-cylinder tractors which led to the great success of John Deere as a tractor manufacturer until that time. The John Deere 4010 was an American farm tractor in production by the John Deere Company from 1960 to 1963.
