Introduction
John Deere 8320RT Agricultural Crawler Tractor
The John Deere 8320RT is a high-horsepower agricultural crawler tractor manufactured in Waterloo, Iowa, between 2014 and 2019. Designed for heavy-duty field operations, this tracked machine belongs to the 8RT series, providing high traction and soil compaction management for large-scale agricultural tasks.
Engine and Performance
The tractor is powered by a 9.0-liter, 6-cylinder John Deere PowerTech PSS liquid-cooled engine. It utilizes dual variable geometry turbochargers to achieve a gross rated power of 320 hp (238.6 kW). The engine complies with Tier 4B emission standards through the use of selective catalytic reduction technology.
Transmission and Drivetrain
The 8320RT is equipped with the John Deere AutoPowr transmission, which is an infinitely variable transmission (IVT) system. This setup allows for seamless speed adjustments in both forward and reverse directions without the need for traditional gear shifting, optimizing efficiency for various load requirements.
Hydraulics and Hitch
The hydraulic system features a closed-center, load-sensing design with pressure and flow compensation. It provides a standard pump flow of 60 gpm (227.1 lpm), with an optional 42 gpm configuration available. The rear hitch is a category IVN/III system capable of lifting 15,000 lbs (6,804 kg), with an optional upgrade to 20,000 lbs (9,072 kg) capacity.
Operator Environment
Standard equipment includes the CommandView III cab, which is designed to provide operator comfort during extended operation cycles. The cab is fully climate-controlled and serves as the central interface for monitoring the tractor's integrated systems.
Power Take-Off
The machine features an independent rear PTO operating at 1000 rpm with 1.75-inch shaft specifications. An optional independent front PTO is also available, providing additional flexibility for front-mounted implements.
Conclusion
The John Deere 8320RT is engineered for demanding agricultural environments where high drawbar pull and consistent performance are required. Its tracked configuration, combined with advanced hydraulic and transmission systems, makes it a reliable choice for heavy tillage and large-area cultivation.
