Common questions
International Harvester 660 weight FAQ
How much does an International Harvester 660 weigh?
The International Harvester 660 weighs 9,635 lb (4,370 kg) using the published Operating — gas figure. Across the published configurations on this page, weight ranges from 9,635 to 15,255 lb (4,370 to 6,919 kg).
What is the operating weight of the International Harvester 660?
The published operating weight is 9,635–9,875 lb (4,370–4,479 kg). This is usually a more useful real-world figure than a bare shipping specification, although ballast, loader, fuel, implements and tire setup can still increase actual working weight.
How much does the International Harvester 660 weigh with ballast?
The published ballasted weight is 15,255 lb (6,920 kg). That is up to 5,620 lb (58.3%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the International Harvester 660 a heavy standard-tread tractor?
Yes. The representative figure sits at about the 73rd percentile, heavier than roughly 73% of the standard-tread tractor peers. That puts it in the heavy range for this comparison. It is 1,236 lb heavier than the peer-group average of 8,399 lb.
How wide is the International Harvester 660 for transport?
The maximum published tractor width is 78 in (6.5 ft). That is 24 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
Does the International Harvester 660 weigh more than 10,000 lb?
Some configurations do. The representative published weight is 9,635 lb, and the heaviest published configuration on this page is 15,255 lb (7.63 US tons). Any trailer calculation also needs the trailer itself plus fuel, ballast, attachments and other equipment.
