I've hit 2 "memorable" stumps so far.. On my pro-slide, whizzing along a straight run.. Forgot about the sawed off at 3" level fence post in the middle of the yard, maybe it was an old clothesline? I dunno. WHAM. I hit my left hip bone, I'm tall and skinny as well,. Man left a black and blue mark on my hip like I got clubbed by a baseball bat..
Another time, hit some other tree stump, flew forward about 8 inches into the handle bars. My left thumb slammed into the pistol grip latch system, I swore I broke my thumb off. Blood came out of the knuckle, immediate pain, the whole deal. And I still had to control the mower cause after the mower hit the stump, it spun off to the right and was heading about 3 feet away from going right through a stockade fence.... Thumb luckily was just bruised and had a cut that wasn't deep, just seemed to bleed alot.. Thank goodness...
