What the 7520 is used for

The 7520 was designed to pull large tillage implements on broad-acre farms. Its four-wheel drive and high drawbar power made it a natural fit for plowing, disking, and other high-draft field work.

Today, surviving tractors are used at shows, in vintage field demonstrations, and for occasional farm work. It rewards owners who can support an older 4WD drivetrain and work safely with a large, heavy machine.

The 7520 is notable as one of Deere's early high-horsepower four-wheel-drive tractors. Its tested 175 PTO horsepower, robust 8.7 L diesel, and relatively limited production make it a memorable and sought-after classic.
