John Deere 9520T

Last Updated: July 2024

Overview

The John Deere 9520T is a track tractor known for its significant pulling power and ability to manage heavy-duty tasks on large farms and fields. Featuring an electronic-hydraulic power steering system, it provides ease of control even when dealing with challenging terrain. The tractor is driven by a liquid-cooled, six-cylinder turbocharged diesel engine with a displacement of 765 cubic inches, producing 333 horsepower at rated speed, with a maximum of 371.54 hp at 1700 rpm. A John Deere PowerShift transmission manages the power with 18 forward and 6 reverse gears. The long 111-inch wheelbase and track system offer superior traction and weight distribution, essential for minimizing soil compaction. The operator enjoys the comfort and convenience of a cab environment, and with the rear three-point hitch (categories III, IV/IVN) capable of exerting a maximum force of 14,921 pounds, the 9520T is equipped for a wide variety of implements.
