Hauling 8 yds of topsoil from driveway to garden today. Full ballast as always when running a full 120 bucket. Next to last scoop, I gave it a curl shake to level the dirt, backed up away from dirt pile in driveway and left tire flipped about 70 degrees sideways. Stopped moving and lifted front end with bucket. Left pivot arm lifted out of axle. What failed and what's the fix? I left it lifted and shut it down. Suggestions?
