About the International Harvester 684

Production of the International Harvester 684 Tractor started in 1977 and continued until 1984. Regardless of whether you initially got a deal on your tractor (lower than the initial price of $21,100 (1984)), 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 684 Tractor running smoothly. Sometimes, the parts compatibility is determined by the serial number of your International Harvester 684 Tractor, and that info should be listed on the part fit notes. If you don't have the serial number of your tractor, you can find it on the front axle support on right side of tractor. The serial number starts from 501 for a 1978 model, from 1687 for a 1979 model, from 3533 for a 1980 model, from 6037 for a 1981 model, from 8001 for a 1982 model, from 8512 for a 1983 model. Some International Harvester 684 Tractors have a 4x2 2WD chassis, but there are also some with a 4x4 MFWD 4WD optional chassis, all equipped with hydrostatic power steering. They also have independent hydraulic wet disc brakes. The type 2 3-point hitch is very reliable, capable to lift 3600 lbs [1632 kg]. It is also worth noting that the independent rear PTO runs at 540 rpms. The International Harvester 684 has an open center hydraulics system with a 9 gal [34.1 L] capacity. The pump does the job pushing 13 gpm [49.2 lpm] fluids in the hydraulics system.
