Abstract
Abstract A power attachment unit for golf bag carts comprising a curved support tube whose lower end is fixed to an inverted yoke support having mounted therein a wheel to be power driven by means of a motor and gear assembly mounted to one side of the yoke support. To the other side of the yoke support is fixed a battery case containing a battery for energizing the motor. The support tube is mounted to the vertical stem of the push cart by means of a releasable and adjustable clamping bracket. An electrical control unit is mounted by a second clamping bracket to the handle of the push cart for controlling the speed of the motor and in turn the power driven wheel. Electrical lines between the control unit and the battery and the motor are partly housed through the support tube.
