well, just started using my newly aquired 1600 and was moving a little dirt around the yard. Tractor runs great, hydraulics are excellent but after moving maybe 10 bucket fulls of dirt, the left front spindle/king pin piece snaps clean off about 3 inches from the spindle!! Was very surprised to see it is made of cast and not a solid piece of steel. I was digging dirt from a spill pile that our basement was dug from. Maybe I was digging too hard into the pile? I have used Michigan loaders and case skidsteers for years where I work and have never experienced anything like this before. Any insight would be greatly appreciated. sorry for the long winded post.
