Had an issue earlier this year with my trailer and my son's Kubota. We needed it as a mower, so (belly mount) deck was a necessity. Couldn't get it ( the deck) between the wheel wells on my trailer, back wheels were barely on the trailer deck, and the trailer came off the ball and smashed the tailgate on my old Dakota.
I could understand it possibly getting squirrelly being loaded so far back, and only having to go like 10 miles with it on gravel country roads, I kept it under 30 mph the whole way so it wouldn't sway on me (it didn't at all at those low speeds)
I still can't get over why it uncoupled itself off the ball when it was correctly patched and the latch handle had a padlock thru it to keep it from popping up.actually it didn't uncouple, it came off the (correct sized) ball still coupled and locked. Twice.
I did replace the coupler on it since, figuring it must have just been old, (original coupler put on that frame in 1974)
haven't had that happen again since but haven't pulled that tractor with it's deck mounted since, either. I've pulled that tractor on the same trailer without the deck though.
