John Deere 5020 Tractor Parts

5020 parts and accessories

The John Deere 5020, manufactured from 1965 to 1972, was a powerful workhorse known for its robust construction and ability to handle demanding tasks. Powered by a 135 horsepower diesel engine and offering a substantial PTO horsepower, the 5020 became a popular choice among farmers for tillage, planting, and other heavy-duty operations. This tractor helped define a generation of agricultural equipment.

The John Deere 5020 was introduced in 1965 as a larger, more powerful tractor option within the John Deere lineup, filling the need for increased horsepower and capability. Production continued until 1972. The 5020 was equipped with a John Deere 404 cubic inch, 6-cylinder diesel engine producing approximately 135 horsepower. This engine delivered ample power for a variety of demanding farm tasks. The transmission was a Syncro-Range transmission, offering 8 forward and 2 reverse speeds. The PTO delivered around 115 horsepower at 1000 RPM. The hydraulic system provided a flow rate of approximately 22 GPM, with typically two remote valves. The 3-point hitch was a Category II, offering a lift capacity of around 5,500 lbs. Common applications included row crop farming, hay production, and tillage operations. What distinguished the 5020 from other John Deere models of the time was its larger size, heavier frame, and increased horsepower, making it suitable for larger farms and more demanding tasks than its smaller counterparts, such as the 4020.
