Common questions
Case IH STX440 weight FAQ
How much does a Case IH STX440 weigh?
The Case IH STX440 weighs 39,325 lb (17,837 kg) using the published Operating figure. Across the published configurations on this page, weight ranges from 39,325 to 52,800 lb (17,837 to 23,950 kg).
What is the operating weight of the Case IH STX440?
The published operating weight is 39,325 lb (17,838 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 Case IH STX440 weigh with ballast?
The published ballasted weight is 44,560 lb (20,212 kg). That is up to 5,235 lb (13.3%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the Case IH STX440 a heavy farm tractor?
Yes. The representative figure sits at about the 96th percentile, heavier than roughly 96% of the all tractors in this dataset. That puts it in the very heavy range for this comparison. It is 29,398 lb heavier than the peer-group average of 9,927 lb.
How wide is the Case IH STX440 for transport?
The maximum published tractor width is 44 in (3.7 ft). That is 58 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
Does the Case IH STX440 weigh more than 10,000 lb?
Yes. The representative published weight is 39,325 lb, and the heaviest published configuration on this page is 52,800 lb (26.4 US tons). Any trailer calculation also needs the trailer itself plus fuel, ballast, attachments and other equipment.
