Introduction
John Deere 8320R Row-Crop Tractor
Produced between 2014 and 2019 in Waterloo, Iowa, the John Deere 8320R is a high-horsepower row-crop tractor designed for heavy-duty agricultural operations. This model belongs to the 8R series, engineered to provide high traction and precise implement control in demanding field environments.
Engine and Performance
The tractor is powered by a 9.0-liter, 6-cylinder John Deere PowerTech PSS engine. It features a turbocharged, aftercooled design with an electronic high-pressure common rail fuel system. The engine produces a rated power of 320 hp and a maximum gross power of 352 hp. It complies with Tier 4B emission standards through the use of selective catalyst reduction technology.
Transmission and Drivetrain
Operators can choose between two transmission systems: a 16-speed full PowerShift transmission or the AutoPowr infinitely variable transmission (IVT). The tractor utilizes a four-wheel-drive system with inboard planetary final drives and hydraulic wet disc brakes. Active Command steering is available as an option to improve handling.
Hydraulics and Hitch
The hydraulic system is a closed-center, load-sensing design with pressure and flow compensation. It provides a standard pump flow of 60 gpm, with an optional 85 gpm capacity. The rear hitch is a Category IVN/III system capable of lifting 15,000 lbs. An optional front hitch with a 11,450 lbs lift capacity is available for additional implement versatility.
Operator Environment
The tractor is equipped with the CommandView III cab, which includes standard air conditioning. The platform is designed for precision farming, being fully AutoTrac ready and equipped with JDLink and ServiceADVISOR Remote capabilities to facilitate fleet management and diagnostics.
