Last Updated: July 2024

Overview

The John Deere 9470RX is a high-powered tractor designed for heavy-duty farming tasks. It boasts a 6-cylinder vertical, liquid-cooled, turbocharged diesel engine from John Deere's PSS series, with two turbochargers, an air-to-air aftercooler, and DEF exhaust treatment. The engine has a displacement of 826 cubic inches and produces up to 470 horsepower. It features a selective gear fixed ratio transmission with full range operator-controlled power shift, offering 18 forward gears and 6 reverse gears for precise handling and efficient field operation. The tractor has an unladen weight of 60,050 lbs, ensuring stability on various terrains. Its extended length and width provide a substantial operating platform. The hydraulic system is closed-center and pressure/flow compensated, with detailed performance specifications available from independent testing. With Tier IV emissions compliance, it also takes into account environmental concerns. The 9470RX's track system provides reduced ground pressure, enhancing traction and minimizing soil compaction.
