The first International Harvester B275 Tractors went out of the factory gates in 1958 and they kept building them until 1968. Regardless of whether you initially got a deal on your tractor (lower than the initial price of $2,800 (1961)), with TractorJoe you'll get the best deal on the spare parts you need. You can find in our inventory every kind of spare part you might need to keep your International Harvester B275 Tractor running smoothly. Make sure you have access to your tractor serial number, because there is a chance that the International Harvester B275 parts you need depend on that serial number. Usually, the serial number is printed on clutch housing, right side. That serial number is determined by the year of manufacturing, so for a 1958 model, it starts with 501, for a 1959 model it starts with 633, for a 1960 model it starts with 12161, for a 1961 model it starts with 29468, for a 1962 model it starts with 39540, for a 1963 model it starts with 43120, for a 1964 model it starts with 46418, for a 1965 model it starts with 48977, for a 1966 model it starts with 51040, for a 1967 model it starts with 52933, for a 1968 model it starts with 54712. The type 1/2 3-point hitch is very reliable. It is also worth noting that the live rear PTO runs at 540 rpms.
