Introduction
John Deere 8R 340 Row-Crop Tractor
The John Deere 8R 340 is a high-horsepower row-crop tractor manufactured in Waterloo, Iowa, USA. Part of the 8R series, this model was introduced in 2019 to address intensive agricultural operations requiring significant traction and implement management.
Engine and Powertrain
The tractor is powered by a 9.0-liter, 6-cylinder turbocharged diesel engine with a liquid cooling system and electronic high-pressure common rail fuel injection. It delivers a rated power of 340 hp at 2100 RPM and a maximum gross power of 374 hp. The engine utilizes a 16.0:1 compression ratio and is compliant with Tier IV emission standards.
Transmission and Drive
Power is transferred via two available transmission options: the e23 full power shift transmission, providing 23 forward and 11 reverse gears, or an infinitely variable transmission (IVT). The machine features a four-wheel drive configuration supported by inboard planetary final drives and power steering for improved maneuverability.
Hydraulics and PTO
The hydraulic system utilizes a closed-center, pressure-flow compensated design with a standard pump flow of 60 gpm (227.1 lpm), which can be upgraded to 84 gpm (317.9 lpm). It operates at a pressure of 2958 psi. The rear power take-off (PTO) is independent and uses an electro-hydraulic wet disc clutch, available with 1000 RPM settings. An optional independent front PTO is also available.
Hitch and Dimensions
The tractor features a category IVN/III rear hitch with electro-hydraulic draft sensing, capable of lifting 20,000 lbs at 24 inches behind the hitch point. The front hitch provides a lift capacity of 11,464 lbs. The unit sits on a 120.1-inch wheelbase with an operating weight of approximately 28,530 lbs depending on configuration.
Conclusion
The John Deere 8R 340 is engineered for large-scale farming applications that demand high hydraulic capacity, versatile transmission options, and substantial pulling power. Its design focuses on operator ergonomics and heavy-duty field performance.
