摘要： A control lever for a control console of a work vehicle comprises an arm and a knob. One end of the arm is coupled to the control valve linkage for positioning the control valve. The other end of the arm is mounted to the knob. The knob is provided with a cylindrical shaft having a first groove and a second groove. The first and second grooves adjoin one another. The first groove is deeper than the second groove. A rubber boot extends between the knob and the control console. The rubber boot has a circular control lever opening through which the control lever extends. The circular control lever opening is provided with an inwardly extending flange. The inwardly extending flange is received in the first groove. A downwardly extending foot extends from the inwardly extending flange and is received in the second groove. The inwardly extending flange and the foot are separated from one another by a step that corresponds to the radial differences between the first and second grooves.
