About the International Harvester 300

International Harvester started producing the 300 Tractor in 1955 and continued until 1956. You may have gotten a good deal and purchased your International Harvester 300 Tractor for less than the initial price of $2,900 (1956), but when it comes to spare parts for the International Harvester 300 Tractor, you will always get the best deal with us. Make sure you have access to your tractor serial number, because there is a chance that the International Harvester 300 parts you need depend on that serial number. Usually, the serial number is printed on the attached to the tractor's clutch housing. That serial number is determined by the year of manufacturing, so for a 1955 model, it starts with 501, for a 1956 model it starts with 20219, for a final model it starts with 33664. They also have differential mechanical disc brakes. The 3-point hitch is very reliable. It is also worth noting that the transmission rear PTO runs at 540 rpms.
