Abstract
Abstract A grass catcher for a riding mower, comprising a stationary subassembly adapted to be secured to the rear of the ride-on vehicle and a bag support frame mounted for pivotal movement on the stationary subassembly. A grass collector bag is carried by the bag support frame, and a cover member is hingedly connected to one side of the bag support frame. The pivotal connection between the bag support frame and the stationary subassembly on which it is pivotally mounted is of hollow ring-like shape whereby to permit the end of the stationary grass delivery tube to extend through the ring-like pivotal connection and into overlying discharging position relative to the grass collector bag carried by the pivotally mounted bag support frame. A handle mounted on the bag support frame permits the operator to pivotally swing the bag support frame and the grass collector bag carried thereby to dumping position about the pivotal support for the frame, the bag support frame also at the same time pivoting about the stationary grass delivery tube. During the dumping operation the cover member which is normally seated in closed position on the bag support frame swings open about a hinge connection of the cover to the bag support frame, whereby to permit the contents of the grass collector bag to discharge during the dumping operation. When the pivotally mounted bag support frame is returned to normal grass collecting position, the cover member returns to closed seated position on the bag support frame.
