Used to work for Gleaner. Back in the early 1980's a safety regulation required testing stopping distance from full speed at max load. Okay, we did have a decal on the ends of big corn heads saying not to drive faster than 10 mph, but that won't stop somebody from doing it (like me for instance). Our test engineer decided to try it with an old test N7 that had seen its better days, and a proto 12 row corn head. Full grain bin, of course. Full speed, hydro to neutral and hit both wheel brakes at the same time. Front end into the asphalt hard enough to rip out the lower header hooks and detached the uppers. That let the rear end slam down from a height up somewhere near the sun. Most of the grain was still in the bin adding momemtum to the impact. It ripped the rear crossmember out of the frame and the axle ended up a few feet away attached only by the steering hoses. So if you ever wondered--- By the way, when we measured everything up it easily passed the braking requirement.
