An extender is positioned on the forward ends of the boom arms of a tractor loader. The extender includes a frame which is pivotally mounted on the forward ends of the boom arms and a slide which is vertically movably mounted on the extender frame. A cable is connected at one end thereof to the slide and extends therefrom over a pulley arrangement which causes the slide to be vertically moved relative to the extender frame as the boom arms are vertically moved relative to the tractor.
