Common questions
International Harvester W-400 weight FAQ
How much does an International Harvester W-400 weigh?
The International Harvester W-400 weighs 6,158 lb (2,793 kg) using the published Operating — gas figure. Across the published configurations on this page, weight ranges from 6,158 to 10,453 lb (2,793 to 4,741 kg).
What is the operating weight of the International Harvester W-400?
The published operating weight is 6,158–6,550 lb (2,793–2,971 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 W-400 weigh with ballast?
The published ballasted weight is 10,453 lb (4,741 kg). That is up to 4,295 lb (69.7%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the International Harvester W-400 heavy or light for a farm tractor?
It is close to average for its peer group. The representative figure sits at about the 48th percentile, near the middle of the all tractors in this dataset. That puts it in the average range for this comparison. It is 3,769 lb lighter than the peer-group average of 9,927 lb.
How wide is the International Harvester W-400 for transport?
The maximum published tractor width is 76 in (6.3 ft). That is 26 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
Does the International Harvester W-400 weigh more than 10,000 lb?
Some configurations do. The representative published weight is 6,158 lb, and the heaviest published configuration on this page is 10,453 lb (5.23 US tons). Any trailer calculation also needs the trailer itself plus fuel, ballast, attachments and other equipment.
