More about the International Harvester 6388

International Harvester started producing the 6388 Tractor in 1981 and continued until 1984. The International Harvester 6388 Tractor first came out at a price of $61,400 (1984), 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 6388 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. Make sure you have access to your tractor serial number, because there is a chance that the International Harvester 6388 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 8962, for a 1983 model it starts with 9060, for a 1984 model it starts with 9241, for a 1985 model it starts with 9361. The type 3, 2 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 540/1000 rpms. The International Harvester 6388 has a closed center hydraulics system with a 23.6 gal [89.3 L] capacity. The pump does the job pushing 18 gpm [68.1 lpm] fluids in the hydraulics system.
