The Farmall F-20 was originally advertised as the "Increased-Power Farmall", and was similar to the orginal Farmall. The tractor paint scheme changed from gray to red on November 1, 1936 (the beginning of the 1937 production year). A number of F-20s were built in early 1934 using the Farmall Regular rear end and F-20 engine. These tractors are identified by a TA serial number prefix.
