Common questions
Allis Chalmers 7580 weight FAQ
How much does an Allis Chalmers 7580 weigh?
The Allis Chalmers 7580 weighs 23,510 lb (10,664 kg) using the published Operating figure. Across the published configurations on this page, weight ranges from 23,100 to 25,000 lb (10,478 to 11,340 kg).
What is the operating weight of the Allis Chalmers 7580 compared with shipping weight?
Published operating weight is 23,510 lb (10,664 kg), versus 23,100 lb (10,478 kg) for shipping weight. That is roughly 410 lb (1.8%) more than shipping weight. Operating weight is generally the more useful starting point when estimating a ready-to-use tractor.
How much does the Allis Chalmers 7580 weigh with ballast?
The published ballasted weight is 25,000 lb (11,340 kg). That is up to 1,900 lb (8.2%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the Allis Chalmers 7580 a heavy farm tractor?
Yes. The representative figure sits at about the 91st percentile, heavier than roughly 91% of the all tractors in this dataset. That puts it in the very heavy range for this comparison. It is 13,583 lb heavier than the peer-group average of 9,927 lb.
How wide is the Allis Chalmers 7580 for transport?
The maximum published tractor width is 95.5 in (8 ft). That is 6.5 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
Does the Allis Chalmers 7580 weigh more than 10,000 lb?
Yes. The representative published weight is 23,510 lb, and the heaviest published configuration on this page is 25,000 lb (12.5 US tons). Any trailer calculation also needs the trailer itself plus fuel, ballast, attachments and other equipment.
