John Deere 7520 (1972-1975)

The John Deere 7520 is a historical model produced between 1972 and 1975, featuring an articulated 4WD chassis designed for demanding farm tasks. It offers two partially synchronized transmissions options with the higher capacity offering 16 forward and 4 reverse gears. The tractor is powered by a 531 cubic-inch, six-cylinder, liquid-cooled, turbocharged and intercooled diesel engine that delivers 175 horsepower at 2100 RPM. It incorporates hydrostatic power steering and integral hydraulic wet disc brakes for efficient operation. The robust vehicle has an operating weight of 16,800 pounds and includes a cab for operator comfort. With a substantial fuel tank capacity of 156 US gallons, the JD 7520 ensures long operating intervals. Equipped with a 40 quart cooling system and a closed center hydraulic type with a pump flow of 21.0 gpm, the tractor is capable of handling tough jobs with ease. Although the manual lists two types of transmissions, a Syncro-Range with 8 forward and 2 reverse gears and a Syncro-Range Hi-Lo with 16 forward and 4 reverse gears, the presence of both in this specific tractor model is uncertain.
