This model 6788 is part of International Harvester’s 2 2 series tractors. The 6788 replaced the 3788 in 1983, followed by the 70 series tractors in 1984, the last in the 2 plus 2 series. When the J. I. Case Company purchased the agricultural division in 1985, it ceased production on all tractor models International Harvester had in development. #classictractorfever #classictractortv #aumannvintagepower #internationalharvester #4wdtractor #bigfarmpower #bigtractorpower #fourwheeldrivetractor #far
