John Deere 8370RT

Last Updated: July 2024

Overview

The John Deere 8370RT is a high-powered agricultural crawler tractor equipped with a rubber tracked chassis. Its 359.53 hp PowerTech PSS engine meets Tier 4B emissions standards through selective catalytic reduction and is rated at 2100 rpm. The liquid-cooled 6-cylinder engine has a displacement of 548 cubic inches, a bore of 4.66 inches, and a stroke of 5.35 inches. It features dual variable geometry turbochargers and a thermostat with variable speed fan for temperature control. The tractor has a selective gear fixed ratio transmission with 22 forward and 12 reverse gears, providing full range operator-controlled power shift. Key performance metrics include a maximum torque of 1139 lb-ft at 1601 rpm with a 41.9% torque rise, and a hydraulic system capable of exerting up to 22,144 lbs of force with a pump delivery rate of 61.7 GPM at 2517 psi. Detailed drawbar performance, fuel consumption, and other operational data are available from independent test results.
