ABSTRACT:
A compact, light weight and easily detachable power unit for driving a golf bag cart by means of an electric motor carried by the unit. The unit includes an articulated frame having an attaching portion which is quickly attachable to or detachable from the frame of the golf bag cart and this attaching frame also carries the battery. The articulated frame also includes a motor and wheel driving frame which is pivotally mounted to the attaching frame about a generally vertical axis and extends generally downwardly and rearwardly therefrom and has a ground wheel at the lower end thereof for castering relative to the attaching frame. An electrical control circuit includes an electric motor carried by the wheel driving frame and also includes the battery, a transistor, a resistor, and a manually operated variable resistor controller on the golf bag cart to infinitely vary the driving speed of the motor.
