John Deere 9420R Specs ( 2015-2021 )

Name: John Deere 9420R
Brand: John Deere

Overview

The John Deere 9420R is a high-capacity four-wheel drive farm tractor built in Waterloo, Iowa, featuring a John Deere 13.5L 6-cylinder diesel engine with a maximum gross power of 462 hp. Equipped with an e18 PowerShift transmission and a 310-gallon fuel tank, this articulated machine is designed for heavy-duty agricultural tasks requiring significant hydraulic output and traction.

Ideal Applications

Heavy Tillage and Field Prep: With a ballasted weight of 48,700 lbs and 420 rated gross horsepower, this tractor provides the mass and engine power necessary for pulling large-scale tillage implements across expansive acreage.

High-Demand Hydraulic Operations: The closed-center pressure/flow compensated hydraulic system offers a 58 gpm pump flow and supports 4 to 8 rear valves, making it suitable for modern implements that require high-pressure fluid power.

Precision Field Work: The Command View Cab III is standard with AutoTrac and JDLink readiness, allowing operators to utilize integrated technology for efficient, automated steering and fleet management.
