A rotary drum subassembly is mounted in the drum housing for rotation about a horizontal axis, and includes axially and circumferentially spaced blades mounted on spacer sleeves. The sleeves are mounted on an elongated shaft. A thatch-catching bag is detachably mounted on the drum housing at a location for catching thatch discharged through the thatch discharge opening in the housing.
