Well as far as the rollovers, the first one was my fault, going too fast in a rough field and hit a washout. But the second one was a steering failure, and was unavoidable. And both rollovers were on tricycle tractors. But after doing some asking around, it looks like I'll be buying a 4230 row crop locally, instead. Still a tall tractor compared to my 3020, but far from the hi crop
