More about the John Deere 420

The John Deere 420 Tractor was manufactured between 1956 and 1958. Make sure you have access to your tractor serial number, because there is a chance that the John Deere 420 parts you need depend on that serial number. Usually, the serial number is printed on the left side of tractor frame. That serial number is determined by the year of manufacturing, so for a 1956 model, it starts with 80001, for a 1957 model it starts with 107813, for a 1958 model it starts with 127782. Some John Deere 420 Tractors have a 4x2 2WD chassis, but there are also some with a power optional chassis, all equipped with manual steering. The type I 3-point hitch is very reliable. It is also worth noting that the transmission rear PTO runs at 540 rpms.
