  • Patent number: 4137693
    Abstract: A portable frame adapted to be mounted on a beach adjacent a lake. The portable frame has a reversible motor and a pair of drive wheels driven by the motor. A rake is provided with an elongated handle. The drive wheels of the frame are adapted to engage the handle of the rake to move the rake backward and forward powered by the motor. The rake has teeth which fold inward when the rake is moved forward into the lake along the lake floor powered by the motor and the teeth will remain upright when the rake is powered back out of the lake, so that the teeth will engage the weeds and will take or pull the weeds out of the bottom of the lake as the rake is powered back out of the lake.
