Abstract
Abstract An adjustable control attachment includes a pivot plate pivotally attached to each side of a control console with a control lever shaft connected and movable with each pivot plate. A plurality of control levers are pivotally mounted on each shaft and a flexible control cable is connected to each lever and adapted to be connected to a hydraulic control valve. A cable supporting bracket is connected to each of the pivot plates and is connected to and supports the control cables. A control actuating rod is pivotally connected between the vehicle and each of the pivot plates for creating an elliptical movement of the controls as the console is moved.
