A rake apparatus includes an elongated handle with an upper wall, a peripheral wall, and an open bottom end. A head is attached to the bottom end and has a bottom surface having an opening therein. Each of a plurality of first teeth is attached to the head. An axle is mounted within the opening. A pawl is rotatably mounted on the axle. The pawl includes a first arm and a second arm orientated generally perpendicular to each other. The second arm extends downwardly through the opening. Each of a plurality of second teeth is attached to the second arm. An actuator is coupled to the first arm and is adapted for selectively urging the first arm upwardly. The actuator may be selectively actuated so that the second teeth are moved toward the first teeth.
