Control lever assembly

A control lever for a work vehicle having a work implement is provided with a shaft that operates a control linkage. The shaft and control linkage control two functions of the work implement by manipulating two hydraulic control valves. The shaft can be moved in two orthogonal directions or arcs. To prevent cross talk between the control functions the control lever is prevented from twisting by a stub shaft that is received in an elongated slot. The side walls of the elongated slot restrain the twisting movement of the control lever. The elongated slot is provided with a U-shaped slider made of an anti-friction material such as slippery urethane plastic. The U-shaped slider has legs that conform to the side walls of the elongated slot. That portion of the stub shaft located in the elongated slot has a cylindrical configuration.
