John Deere 2040 Tractor Parts
The John Deere 2040 was a popular utility tractor produced from 1973 to 1977, offering versatility and reliability for a variety of farm tasks. Powered by a 58 horsepower diesel or 62 horsepower gasoline engine, it provided sufficient power for many small to medium-sized farming operations. Its PTO horsepower of around 50 HP made it well-suited for running implements like mowers, balers, and tillers, making it a farmer favorite.
The John Deere 2040 was introduced in 1973 as part of the '40 Series' line, replacing the earlier John Deere 2030. Production continued until 1977. Engine options included a John Deere 3.9L (239 cu in) 4-cylinder diesel engine producing approximately 58 horsepower, and a 3.0L (183 cu in) 4-cylinder gasoline engine with about 62 horsepower. The 2040 typically featured a gear-type transmission, offering various speed options, such as an 8-speed forward and 4-speed reverse transmission. PTO horsepower was rated at around 50 horsepower, with a standard 540 RPM PTO. Hydraulic capacity was approximately 14 GPM, powering functions like the 3-point hitch and hydraulic remotes. The 3-point hitch was typically a Category II, providing a lift capacity of around 3000 lbs. Common farming applications for the 2040 included row crop cultivation, hay production, livestock feeding, and light tillage work. Compared to smaller models in the John Deere lineup, the 2040 offered more power and versatility, while remaining a manageable size for smaller farms.
