Woman killed by rock thrown from DOT mower - "Cook said a similar incident occurred in Troup County a few years ago, when a prisoner on a work detail was hit in the jugular by a rock thrown from a mower. The prisoner, who Cook said was scheduled to be released the next day, died."
Running a lawnmower without the grass catching bag or covering the discharge chute can be very dangerous! Rocks, sticks, and other debris can be shot or thrown at the person operating the mower or even other people and children nearby.
