Abstract: The invention disclosed herein is a debris bag for a push-type lawn comber. Such a lawn comber is representative of similar devices such as lawn mowers and sweepers, in are provided with a rearwardly extended push handle. The lawn comber carries an array of radial impact arms upon a transverse shaft within the body of the comber. Rotation of the shaft and impact arms upon it by a power drive throws debris through a chute at the rear of the machine. A bag is carried upon a frame which latches itself to the chute and cantilevers rearwardly from the chute to define the top of the bag. A closure cover fits over this bag top to enclose it when the unit is n operation. A lever is used to engage the impact arm shaft with the power drive. Whenever the lever is depressed rearwardly alongside the bag, engagement occurs.
