Abstract
Abstract A riding type mower is provided with a grass catcher attachment having removable container and cover structures. The container structure includes a horizontally disposed quadrilateral frame carrying a large container. The cover structure includes a molded cover and a screen extending downwardly from the cover with resilient clips or latches at the lower edge adapted to snap onto the container frame. A discharge chute from the mower directs the cut material rearwardly to a blower mounted on the rear of the mower. The blower discharge directs the cut grass upwardly toward a deflector formed by the shape of the top of the cover. The user may use the container to catch cut grass or may at his option place three plastic bags, such as garbage can liner bags, in lateral side-by-side relationship inside the container. The plastic bags are held in place by four spring loaded retainers and by the clips which hold the cover structure onto the container frame. The container has tapered front and rear sides to facilitate upward removal of the plastic bags therefrom.
