Overview

The John Deere 9420 is a large, articulated four-wheel-drive tractor designed for heavy agricultural tasks. Manufactured between 2002 and 2007, this model is equipped with a robust 12.5L six-cylinder turbocharged diesel engine, putting out 425 horsepower at 2,100 RPM. Two transmission options were available: a 24-speed partial power shift and an 18-speed full power shift, both providing ample range for various field conditions. The hydrostatic articulated steering and hydraulic wet disc brakes ensure responsive handling and reliable stopping power.

The well-appointed CommandView cab with air conditioning improves operator comfort during long working hours. The 9420's solid build and powerful performance make it a valued asset for any agricultural enterprise seeking efficiency and durability.
