John Deere Hydraulic Parts: Pumps, Valves, and Circuit

Modern John Deere hydraulic circuits operate between 180 and 200 bar for consistent power. Gear pumps equip the classic series (1640, 2130, 2850), while newer models (6155 R, 6120 M, 6250 R) use 41 cm³ piston pumps, allowing precise flow control for lifting and implements.

Our reconditioned valves (refs. AL34593, AL171118, AL207508) cover tractors from the 6000 and 7000 series, from the 6200 to the 6920 S. We also provide solutions for combines (2066, S660, 9780 CTS), where hydraulic block reliability is critical for cutting and threshing.

Preventive maintenance, including seal and filter replacement, ensures optimal durability. From John Deere hydraulic valves to hydraulic couplers, our tested used parts offer an economical and efficient alternative for all models, from the specialized 5500 N to the powerful T660.
