ABSTRACT:
A Christmas tree shaker including a base with a horizontal turntable mounted rotatably thereon on a motor driven shaft. A tree trunk receiving receptacle is mounted on the turntable for limited relative rotation with respect thereto. The receptacle is offset from the turntable axis of rotation. A stabilizer link between the base and receptacle limits the amount of relative rotation between the receptacle and turntable as the motor driven shaft rotates the turntable causing the receptacle to travel rapidly in a tight circle.
