A grass collection cart having an access door and a closed bottom portion receives the airborne grass clippings discharged by a rotary cutting blade assembly. Auxiliary walls on the access door define an air discharge passage having an intake end spaced from the closed bottom portion of the cart and communicating with the interior of the cart when the access door is in its closed position. The discharge passage also has an outlet end opening near the ground. The incoming flow of airborne grass clippings entering the interior of the cart is directed toward the closed bottom portion and away from the intake end of the discharge passage so that the incoming flow of air will be deflected by the closed bottom portion toward the intake end of the discharge passage. The grass clippings consequently settle from the air stream and into the closed bottom portion, and the outgoing flow of air is expelled from the cart through the discharge passage near ground level. In its preferred embodiment, the rotary cutting blade assembly includes a fan system which enhances the flow of airborne grass clippings into the cart.
