The John Deere 720 is a model of tractor that was produced by the company from 1955 to 1957. It was part of the "New Generation" series of tractors and it was considered a medium-sized tractor. The 720 was powered by a two-cylinder gasoline engine, and it was available in both a standard and a row-crop version. It featured a power take-off (PTO) and a live hydraulics system. It was a popular model among farmers and was known for its reliability and versatility. The 720 was replaced by the 730 in 1958, which was similar to the 720 but had a larger engine and other improvements.
