My friend actually survived a similar situation after doing what most would say everything wrong. He was driving his new BX in 2wd down a *steep* concrete drive with the bucket full of dirt, no ballast box, rops up, and no seatbelt. Naturally the rear of the tractor was light, began skidding, accelerated, raised up on the pivoting front axle, tipped over and slid down to the bottom. He said it happened in an instant and jumped away just before it rolled. The roll bar was completely bent over to below seat height.
