I've broken two rear deck hangers in the last few weeks. There are rock outcroppings where I mow and I hit one. The deck hangers are too close to the frame of the mower and there is a ledge on the frame that hits the hanger causing it to break. Below is a picture. as you can see the hangers are rubbing through the paint and there is a dent in the metal on the side frame. Perhaps there should be a hole cut in the side frame in this location or the hangers might be moved towards the inside a little.
