Abstract: An apparatus for selectively changing the neutral position of one or more control levers such as those found on the control console of a motor grader is disclosed. The apparatus comprises a bearing having a longitudinal axis; means for eccentrically mounting the bearing about a central axis which is spaced apart from and parallel to the longitudinal axis, the means for mounting the bearing permitting the bearing to revolve about the central axis; and means for selectively retaining the bearing in a plurality of desired radial positions relative to the central axis, an end of the control lever is secured to the bearing to permit the control lever to pivot about the longitudinal axis. A connecting rod has a first end pivotally connected to the control lever and a second end connected to a device which is to be activated by the control lever. The first end of the connecting rod pivots about an axis which is coincident with the central axis.
