Abstract: Yardage measurement attachments for golf carts and the like normally have to be factory installed or else use a fricton type actuator which slips when wet. The present device can be installed readily and easily and without detaching the wheel from the cart. It includes a split disc which can be bolted to the face of one of the wheels said disc having teeth or notches around one face thereof adjacent the outer rim. These engage with a gear in a converter supported by the axle and the gear drives a flexible cable which in turn attaches to a cutter mounted on or near the handle of the cart. A cable can be attached to the counter to show yardage covered or to show yardage remaining from a preset figure representing the yardage of the particular golf hole being played.
