Last Updated: July 2024

Overview

The Massey Ferguson 8470 is a substantial, powerful tractor well-suited for row-crop operations with a 4WD configuration and 249.3 horsepower engine (based on Nebraska test maximum PTO power). This tractor features hydrostatic power steering, a comfortable cab for prolonged operations, and a Dyna-Step transmission with 21 forward gears and multiple low/high reverse ranges. Its liquid-cooled engine with heat exchanger, built by Sisu Diesel, is a reliable six-cylinder turbocharged intercooled diesel engine, offering robust performance. The 8470 has a closed-center hydraulic system with measured pump delivery of 36.9 GPM and hydraulic power of 47.7 HP at 2335 psi. Tire options include 480/70R34 or 600/70R28 front, and 520/85R46 with duals or 650/85R38 rear. With an operating weight of 20,535 lb without ballast, the 8470 offers high productivity and comfort for large-scale farming.
