John Deere 9620T

Last Updated: July 2024

Overview

The John Deere 9620T is a powerful track tractor designed for heavy-duty agricultural tasks. With a turbocharged and air-air aftercooled diesel engine capable of delivering 500 horsepower at 2100 RPM and a maximum torque of 1233 lb-ft at 1051 rpm, this tractor ensures robust performance in a range of operations. The engine's six inline cylinders and large displacement of 765 cubic inches, combined with a liquid cooling system, assure consistent and efficient workflow, even during extended use. The closed center, pressure-flow compensated hydraulic system has a pump flow capacity of 50 GPM (189.3 l/min) at minimum pressure and rated engine speed, providing a hydraulic power of 64.5 HP (48.1 kW) at a delivery pressure of 2256 psi (155 bar). It can exert a maximum force of 14921 lbs (66.4 kN) at the hitch points (Category IV). This model includes four remote control valves and operates on an electro-hydraulic power steering system. The transmission is a full-power shift, featuring 18 forward gears with speeds ranging from 2.13 mph to 21.14 mph, and 6 reverse gears with speeds matching the corresponding forward gears with some differentials noted. The John Deere 9620T has a sturdy operating weight of 43,380 pounds and an impressive rear hitch lift capacity of 13,871 pounds, making it a formidable machine for large-scale farming operations. Other notable features include a wet multiple disc hydraulically actuated clutch and brake system, a hydraulic oil temperature of 145°F (63°C), and a fuel capacity of 300 gallons.
