About the International Harvester 340

In 1958, the very first International Harvester 340 Tractors went out. They were produced until 1963. The International Harvester 340 Tractor first came out at a price of $3,400 (1963), but you might be one of the lucky ones who found a good deal lower than that. The bad news is that, like any other tractor, the International Harvester 340 Tractor needs spare parts to keep it running; the good news is that we have all the parts you need at 60% off dealer prices in our inventory. Be sure to look for any serial number comments in the part fit notes. In some cases, the International Harvester 340 Tractor parts you need depend on your serial number. You can find the serial number on the clutch housing, right side. Serial numbers include 501 from 1958 models, 2467 from 1959, 5741 from 1960, 8736 from 1961, 11141 from 1962, 12032 from 1963, ? from final. Some International Harvester 340 Tractors have a 4x2 2WD chassis, but there are also some with a hydrostatic power optional chassis, all equipped with manual steering. They also have independent mechanical disc brakes. The 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540 rpms.
