摘要： Improved machines and devices for thatching lawns (thatch meaning grass blades, leaf fragments and particles, weed fragments and particles and the like that collect around and at the bases of blades of grass and the other plants that make up a lawn); a new leaf and thatch raking device employing novel principles of operation and apparatus and structural features whereby to carry out the leaf and thatch raking task most efficiently; devices which (1) not only "reverse rake" a lawn, thereby to effectively pick up thatch, debris, leaf fragments and leaves, while (2) still further taking or forcing the said raked up material into and through a pulverizing or mulching zone and (3) then passing the processed lawn debris material from said zone into a storage container; an integrated leaf raking and thatching system involving highly efficient raking, highly efficient transport of raked materials from the raking zone, direct passage of the said raked material into a comminuting zone of great effectiveness and efficiency, continuous withdrawal of comminuted material from the last mentioned chamber and, thereafter, a process and means for moving and passing the comminuted material to a closed, yet venting container in a continuous manner whereby to retain the comminuted material in the container and vent the air from the container.
