Once tractors go over 3,000 pound bare tractor weight, the FOLDED ROPS is usually taller than 84".
The optimal way to shop for tractors is to list your tasks first, then determine bare tractor weight you need to SAFELY accomplish your tasks. Bare tractor weight is a tractor specification easily found in sales brochures and web sites, readily comparable across tractor brands and tractor models.
Most tractors under 3,000 pounds bare weight operate in residential applications on one to five fairly flat acres. These "residential tractors" fit in a typical garage.
Good point.
Probably 80" is about the max it could be. If a regular sized skidsteer won't fit, then it doesn't really matter if a tractor can since it will be a job for a walk behind skid.
