ABSTRACT:
A wheeled vehicle having a pair of forwardly projecting support arms carrying a rotary dethatching drum. A volute housing encloses the upper portion of said dethatching drum and opens for tangential forward discharge above the drum. The drum includes axially-spaced blades mounted in circumferentially staggered array upon a polygonally cross-sectioned shaft. The drum is supported upon a vertically adjustable gauge roller used to set the working depth of the dethatching blades. The dethatching drum is driven in rotation from the wheeled vehicle. L-shaped lever arms project from the wheeled vehicle toward the dethatching drum and support a foot pedal subassembly which permits the dethatching drum and its housing to be lifted upwardly by foot pressure applied by the operator.
