The John Deere 7020 is a large utility tractor known for its robustness and capability. Built from 1971 to 1975 in Waterloo, Iowa, USA, this four-wheel drive (4WD) tractor is powered by John Deere’s own 6.6 L, six-cylinder turbocharged intercooled diesel engine. It has two transmission options: either a partially synchronized transmission with 8 forward and 2 reverse gears or an upgraded version with 16 forward and 4 reverse gears. The JD 7020 is designed to handle a variety of tasks and comes standard with a cab for operator comfort. It features hydrostatic power steering for ease of maneuvering and a closed center hydraulic system. With a substantial operating weight of 18,495 lbs, this tractor is suited for demanding agricultural operations. The 404 cubic inch engine displacement and the 2200 rated RPM suggest ample power for a range of activities, from plowing to towing heavy equipment.
