Common questions
J.I. Case 431 weight FAQ
How much does a J.I. Case 431 weigh?
The J.I. Case 431 weighs 3,839 lb (1,741 kg) using the published Operating figure. Across the published configurations on this page, weight ranges from 3,375 to 6,355 lb (1,530 to 2,882 kg).
What is the operating weight of the J.I. Case 431 compared with shipping weight?
Published operating weight is 3,839 lb (1,741 kg), versus 3,375–3,495 lb (1,531–1,585 kg) for shipping weight. That is roughly 464 lb (13.7%) more than shipping weight. Operating weight is generally the more useful starting point when estimating a ready-to-use tractor.
How much does the J.I. Case 431 weigh with ballast?
The published ballasted weight is 6,355 lb (2,883 kg). That is up to 2,980 lb (88.3%) above the lightest published configuration. Ballast can therefore change the practical hauling and ground-pressure picture substantially on this model.
Is the J.I. Case 431 a lightweight row-crop tractor?
Yes. The representative figure sits at about the 5th percentile, lighter than roughly 95% of the row-crop tractor peers. That puts it in the very light range for this comparison. It is 10,167 lb lighter than the peer-group average of 14,006 lb.
How wide is the J.I. Case 431 for transport?
The maximum published tractor width is 79.6 in (6.6 ft). That is 22.4 in under 8.5 ft before allowing for a loader, duals, implements or other equipment that may increase transport width.
What is the J.I. Case 431 weight-to-horsepower ratio?
Using the page’s representative 3,839 lb weight and 34 hp power figure, the tractor carries about 112.9 lb per horsepower. A lower lb/hp number means less tractor mass for each horsepower; this is a comparison metric, not a traction or performance rating.
