John Deere 4250 Tractor Parts
4250 parts and accessories
The John Deere 4250, manufactured from 1981 to 1986, was a popular workhorse on farms across the country. Powered by a robust 120-horsepower diesel engine, it delivered a reliable 100 PTO horsepower. Farmers appreciated its versatility and dependability in a variety of agricultural applications, making it a sought-after tractor in its class.
Introduced in 1981 as part of the John Deere Series 50 line, the 4250 quickly gained a reputation for its reliability and power. Production continued until 1986. Under the hood resides a John Deere 6.8L (414 cu in) 6-cylinder diesel engine, producing approximately 120 engine horsepower. The engine is naturally aspirated and designed for efficient fuel consumption. Transmission options included a Quad-Range transmission with 16 forward and 6 reverse gears, providing excellent speed control for different field operations. The independent PTO delivers 100 horsepower at either 540 or 1000 RPM, catering to a wide range of implements. Its hydraulic system boasts a capacity of around 29 GPM, powering two or three rear remotes. The Category II 3-point hitch offers a lift capacity of approximately 6,200 lbs, making it suitable for various row crop, haying, and livestock operations. Compared to models like the 4050 or 4450, the 4250 offered a balanced combination of power and maneuverability, making it an ideal choice for medium-sized farms.
