Abstract
A rotary lawn mower arrangement which reduces the risks of injury from thrown objects by providing two flaps pivoting towards each other, located at the forward and rearward edges of the side outlet and an edge turned upwardly and defining the height of the outlet in the forward portion. The flaps and the upwardly turned edge prevent stones thrown by the rotor from passing through the outlet but allow the cut grass and air to pass therethrough.
