Last Updated: July 2024

Overview

The John Deere 9620R is a 4WD tractor from the 9R series, manufactured by John Deere in Waterloo, Iowa, USA since 2015. The tractor is powered by a 14.9 L (912.0 cu·in) six-cylinder diesel Cummins QSX15 engine and is equipped with an e18 PowerShift transmission, offering 18 forward and 6 reverse gears. With articulated power steering, hydraulic wet disc brakes, and a Command View Cab III standard cabin, the 9620R offers robust features for heavy-duty agricultural tasks. The tractor has a large fuel tank capacity of 400 US gallons and is designed for reliable performance and durability. The specifications have been updated based on independent test results from the Nebraska Tractor Test Laboratory, including corrected operating weight, maximum torque, torque rise, drawbar performance, and additional details on chassis tread width, torque rise at specific RPM, power increase, and hydraulic performance.
