The John Deere hoods are very poorly attached. You can lift the hood with one finger and it's only secured by two plastic half circles and you can then lift it off for service. I ran it into a bush and a limb of the bush entered one of the fins on the side of the hood and lifted it upward and tore the connections off. Also broke the wire to the headlights which later melted and blew the fuse. I suppose I'll have to purchase an entire new hood. This is a small 110 lawn mower and, no, speed and negligence were not factors.
