So today at my dad's work, I was driving a skid-steer around. Fun times! We are levelling out a large dirt pile and putting it in this ditch over this ginormous steel pipe. So I had a big bucketful of dirt and rocks and cinder blocks and heaven only knows what, and I was on my way over to the ditch to dump it out.
Now, skid-steers don't have any sort of suspension, so if you go over a bump, they rock back and forth like a bucking bronco. However, they have a fairly low center of gravity, so usually you are all right.
Unless, of course, you have a heavy bucketful of dirt, rocks, cinder blocks and nameless yard waste, and you are carrying said bucketful way higher than normal bucket position. Such a course of behavior raises the center of gravity significantly and puts it rather far out to the front.
I'm sure you can see where this is going.
