Abstract
A rear dumping brush-type lawn sweeper for attachment to a garden tractor includes a hamper assembly which is mounted on a support frame for pivotal movement. The support frame is carried on the main frame of the brush housing. The hamper assembly carries an open top hamper bag. The top of the bag is normally closed by a mesh-type folding wind apron. A forward portion of the apron is attached to the hamper assembly, while a rear portion of the apron is attached to a rear cross member forming part of the hamper support frame. The wind apron, at its rear terminal end, forms a closure with the rear lip of the hamper bag in the normal running position. When the hamper is rotated rearwardly on the support frame for dumping, the wind screen folds on itself and exposes a rear dumping opening with the rear hamper bag lip.
