A grass dethatching apparatus which includes a frame adapted for mounting the apparatus on a prime mover vehicle. The frame supports a drum housing which defines a thatch discharge opening in the upper forward side thereof. The drum housing carries a pivotably mounted, vertically adjustable roller on the forward side thereof, and a stationary supporting roller on the rear side thereof. A roller actuation system is used to adjust the position of the vertically adjustable roller. 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.
