International Harvester 3388 weight FAQ
How much does an International Harvester 3388 weigh?
The International Harvester 3388 weighs 17,420 lb (7,901 kg) using the published Operating figure. Across the published configurations on this page, weight ranges from 16,340 to 22,000 lb (7,411 to 9,979 kg).
What is the operating weight of the International Harvester 3388 compared with shipping weight?
Published operating weight is 17,420 lb (7,902 kg), versus 16,340 lb (7,412 kg) for shipping weight. That is roughly 1,080 lb (6.6%) more than shipping weight. Operating weight is generally the more useful starting point when estimating a ready-to-use tractor.
How much does the International Harvester 3388 weigh with ballast?
The published ballasted weight is 17,850 lb (8,097 kg). That is up to 1,510 lb (9.2%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the International Harvester 3388 a heavy farm tractor?
Yes. The representative figure sits at about the 86th percentile, heavier than roughly 86% of the all tractors in this dataset. That puts it in the heavy range for this comparison. It is 7,493 lb heavier than the peer-group average of 9,927 lb.
How wide is the International Harvester 3388 for transport?
The maximum published tractor width is 101.6 in (8.5 ft). That is 0.4 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
Does the International Harvester 3388 weigh more than 10,000 lb?
Yes. The representative published weight is 17,420 lb, and the heaviest published configuration on this page is 22,000 lb (11 US tons). Any trailer calculation also needs the trailer itself plus fuel, ballast, attachments and other equipment.
