Overview

The John Deere 4020 series encompasses various models including the standard, row-crop, high-crop, and industrial variants. They were crafted between 1963 and 1972 in Waterloo, Iowa, USA and also in Mexico, highlighting John Deere's commitment to versatility and reliability in their machine manufacturing. The 4020 series tractors are celebrated for their robust construction, high functionality, and the introduction of new features during its production span, such as the option for a full power shift transmission and an optional cabin for operator comfort. It was powered by a range of engines, including diesel, gasoline, and LPG variants, which were all inline 6-cylinder engines with different displacement volumes and compression ratios suited for various tasks and fuel types. With the Syncro-Range and Power Shift transmission options, operators had the benefit of precise control over the tractor's movement and function, complemented by power steering and hydraulic wet disc brakes for easier maneuverability and control.
