Abstract
A control mechanism for independently or conjointly controlling three different functions of an off-highway implement. The control mechanism includes a single, vertical elongated control lever mounted for manipulation in first and second directions about first and second axes and for manipulation through a twisting action about a vertical axis extending substantially perpendicular to the first and second axes. A salient feature of the present invention is that manipulation of the control lever in the first and second directions, conjointly or independently, controls first and second functions of the implement while twisting manipulation of the control lever about its vertical axis controls a third implement function independently or conjointly relative to the other two implement functions.
