The John Deere 4630, manufactured from 1973 to 1977, was a powerful and versatile tractor popular among farmers. It was powered by a robust 150 horsepower diesel engine, providing ample power for various agricultural tasks. With a PTO horsepower of around 125, the 4630 proved its reliability and efficiency, becoming a favorite for row crop operations and general farm work.
The John Deere 4630 was introduced in 1973 as part of the '30 Series' tractors, succeeding the 4620. Production continued until 1977. This model was equipped with a John Deere 6.6L (404 cu-in) six-cylinder diesel engine, delivering approximately 150 horsepower. The engine's robust design made it ideal for demanding farm tasks. Transmission options included a Quad-Range transmission (16 forward and 6 reverse gears) and a Power Shift transmission (8 forward and 4 reverse gears). The PTO delivered around 125 horsepower and offered both 540 and 1000 RPM options, allowing for versatility with different implements. Hydraulic capacity was around 30 GPM with typically two remote valves available. The 3-point hitch was a Category II, offering a lift capacity of around 6,700 lbs. Common farming applications included row crop work, hay production, livestock operations, and tillage. The 4630 was distinguished from other models in the lineup by its higher horsepower and larger frame, making it suitable for larger farms and more demanding tasks compared to models like the 4430 or 4230.
