I never rolled one sideways but stood my loader on its nose once. The bucket on my loader is probably off a backhoe 7 foot wide and should have a 5 foot on it. I was getting better and better at rolling the bucket into the pile getting bigger scopes every time. Then when I had it up high enough to see the sidewalk in front of me, maybe 6 foot high I started rolling the bucket out with hopes of sprinkling gravel as I backed up. That sidewalk came at me very fast and with a thud , my first thought was the back half of the loader with the engine on it broke off, looked back and it was above me,took one hand off the roll bar and pushed the dead man switch on the dash. Pushed the lever and let the loader back down. It seemed like half a second and 1 minute at the same time.
