Introduction
John Deere 3640 Utility Tractor
The John Deere 3640 is a utility tractor produced between 1984 and 1987 in Mannheim, Germany. Designed for heavy-duty agricultural operations, this model is part of the 3140 series and is recognized for its robust construction and mechanical reliability.
Engine and Performance
The tractor is powered by a 5.9-liter, 6-cylinder liquid-cooled diesel engine. It features direct fuel injection and produces a gross power output of 117 hp (87.2 kW) at a rated speed of 2400 RPM. The engine delivers a maximum torque of 290 lb-ft (393.2 Nm) at 1400 RPM, providing the necessary pulling force for demanding field tasks.
Transmission and Drivetrain
Equipped with a Power Synchron transmission, the 3640 offers 16 forward and 8 reverse gears. The system incorporates a partial power shift and a hydraulic cerametallic dry disc clutch, allowing for efficient gear transitions under load. It features a four-wheel drive configuration with planetary final drives and a standard rear differential lock to ensure traction in varied soil conditions.
Hydraulics and Hitch
The hydraulic system utilizes a closed-center constant pressure design, operating at a pressure of 2466 psi. It provides a pump flow of 11.9 gpm (45.0 lpm). The rear hitch is categorized as II/III and utilizes lower-link draft sensing. It is capable of lifting 7930 lbs (3597 kg) at 24 inches behind the lift points, with a maximum capacity of 12818 lbs (5814 kg) at the ends of the arms.
Power Take-Off (PTO)
The tractor is equipped with an independent rear PTO featuring two speeds, 540 and 1000 RPM, selectable at 2175 engine RPM. The PTO system is controlled by a hydraulic wet disc clutch. An optional front PTO is available to increase the versatility of the machine for front-mounted implements.
Conclusion
The John Deere 3640 remains a versatile utility tractor suitable for a wide range of agricultural applications. Its combination of a high-torque 6-cylinder engine, partial power shift transmission, and substantial hydraulic lift capacity makes it an effective tool for both heavy tillage and general farm transport duties.
