I hit a plastic fence post while discing a friends arena, and it did not fare too well. My other dumb FEL trick was to get too lazy to change from the bucket to a hay spear, and get a round bale out of the back of my pickup by dragging it back with the bucket tipped down over the top of the bale. Guess I pushed down a little too hard on the bale, as my tailgate now has a slight U shape to it, and it takes about 3 men and a boy to open the darn thing. These two incidents are the only ones which come to mind right now, but rest assured that you are not alone in this one.
As to the orange paint leaving behind the telltale marks, you could just paint every car and structure you have on the property that same Kubota orange, and then you would not leave such terrible evidence. /w3tcompact/icons/smile.gif
