John Deere 4430 Tractor Parts
4430 parts and accessories
The John Deere 4430, manufactured from 1973 to 1977, was a popular choice for farmers needing a reliable and powerful utility tractor. Powered by a 125 horsepower diesel engine and boasting a PTO horsepower of around 105, the 4430 offered a blend of performance and versatility that made it suitable for a wide range of agricultural tasks. Its robust design and user-friendly features contributed to its enduring popularity.
The John Deere 4430 was introduced in 1973 as part of the '30 Series' tractors, replacing the earlier 4020. Production continued through 1977. This model featured a John Deere 6.6L (404 cu in) six-cylinder diesel engine producing approximately 125 horsepower. Available transmission options included a Quad-Range transmission (4-speed ranges with 4 gears per range) providing 16 forward and 6 reverse speeds, or a Syncro-Range transmission offering 8 forward and 2 reverse speeds. The 4430's PTO delivered approximately 105 horsepower at either 540 or 1000 RPM (depending on the PTO shaft). It had an open-center hydraulic system with a capacity of around 27 GPM and offered two or three remote hydraulic valves. The 3-point hitch was a Category II hitch, capable of lifting around 6,100 lbs. The 4430 was commonly used in row crop operations, hay production, livestock farming, and tillage applications. What distinguished the 4430 from other models in the John Deere lineup was its improved operator comfort, increased horsepower compared to the 4020, and updated styling, making it a significant advancement in tractor technology at the time.
