More about the International Harvester 6788

The original price of the International Harvester 6788 Tractor was $70,500 (1984). If you got it for less, you found a great deal! TractorJoe has plenty of International Harvester 6788 parts to keep it running. Make sure you have access to your tractor serial number, because there is a chance that the International Harvester 6788 parts you need depend on that serial number. Usually, the serial number is printed on the transmission housing, right side. That serial number is determined by the year of manufacturing, so for a 1981 model, it starts with 8801, for a 1982 model it starts with 8810, for a 1983 model it starts with 8840, for a 1984 model it starts with 8871, for a 1985 model it starts with 8946. The type 3, 2 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 1000 rpms.
