Introduction
John Deere 9R 640 Agricultural Tractor
The John Deere 9R 640 is a high-horsepower four-wheel-drive tractor manufactured in Waterloo, Iowa, USA. Part of the 9R series, this model was introduced in 2021 to address the requirements of large-scale agricultural operations requiring significant traction and implement management.
Engine and Performance
The tractor is powered by a 13.6-liter, 6-cylinder, 24-valve turbocharged and aftercooled diesel engine. It utilizes an electronic high-pressure common rail fuel system to optimize combustion. The engine provides a rated gross power of 631.6 hp (471.0 kW) at 2100 RPM and reaches a maximum gross power of 681.2 hp (508.0 kW). Peak torque is rated at 2179 lb-ft (2954.7 Nm) at 1550 RPM, providing the necessary pulling capacity for heavy-duty field work.
Transmission and Drivetrain
Power is transferred through an e18 full powershift transmission, offering 18 forward gears and 6 reverse gears, allowing for precise speed selection under load. The drivetrain features a four-wheel-drive configuration with articulated power steering and inboard planetary final drives. Traction management is supported by electro-hydraulic differential locks on both the front and rear axles.
Hydraulics and PTO
The hydraulic system is a closed-center, pressure/flow compensated type. It features a base pump flow of 55 gpm (208.2 lpm), with optional configurations available up to 110 gpm (416.4 lpm). The system operates at a pressure of 2900 psi (200.0 bar) and supports 4 to 8 SCVs. The rear PTO is an independent unit operating at 1000 RPM with a 1.75-inch shaft.
