More about the International Harvester 3788

International Harvester started producing the 3788 Tractor in 1980 and continued until 1981. The International Harvester 3788 Tractor first came out at a price of $57,000 (1981), 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 3788 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. Sometimes, the parts compatibility is determined by the serial number of your International Harvester 3788 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 right side of tractor frame, by rear axle. The serial number starts from 8801 for a 1980 model, from 10866 for a 1981 model. They also have hydraulic wet disc brakes. The type III 3-point hitch is very reliable. It is also worth noting that the independent rear PTO runs at 1000 rpms.
