John Deere 4230 Tractor Parts

4230 parts and accessories

The John Deere 4230, manufactured from 1973 to 1977, was a popular choice for farmers seeking a reliable and versatile tractor. Powered by a robust 80-horsepower diesel engine, the 4230 delivered ample power for various farming tasks. Its PTO horsepower of around 70 made it well-suited for operating implements like mowers, balers, and rotary cutters.

The John Deere 4230 was introduced in 1973 as part of the '30 Series' tractors, replacing the earlier 4020. Production continued through 1977. The heart of the 4230 is a John Deere 404 CID (6.6L) 4-cylinder diesel engine producing approximately 80 horsepower. A gasoline version was also available, but far less common. The tractor features a Syncro Range transmission with 8 forward and 2 reverse gears, providing a good range of speeds for various field operations. PTO horsepower is rated at approximately 70 HP at 540 RPM, with an optional 1000 RPM PTO available. The hydraulic system delivers around 25 GPM and typically includes two remote valves for implement control. The 3-point hitch is a Category II, capable of lifting around 4,700 lbs. The 4230 was commonly used for row crop work, hay production, livestock operations, and tillage. What set it apart from smaller models in the lineup was its increased power and hydraulic capacity, while remaining more compact and maneuverable than larger frame tractors.
