Last Updated: July 2024

Overview

The John Deere 8345R is a powerful row-crop tractor equipped with a 9.0L six-cylinder vertical turbocharged aftercooled diesel engine with DOC, SCR, and DPF producing up to 325.01 hp at 1802 rpm. It features a selective gear fixed ratio transmission with up to 23 forward gears and multiple reverse gears, with a full range operator-controlled power shift. Key performance metrics include a maximum torque of 1101 lb-ft at 1600 rpm, 44.6% torque rise, and 13.8% power increase at 1802 rpm. The hydraulic system delivers 91.3 hp at 2431 psi with a pump flow rate of 64.4 GPM. Fuel efficiency ranges from 16.14 hp-hr/gal at maximum drawbar power to 18.55 hp-hr/gal at standard PTO speed. Other notable specs are the 4WD chassis, hydrostatic power steering, wet disc brakes, and various hitch/PTO options. Detailed performance data under load conditions is now included.
