Abstract (en)
[origin: US4664220A] A method of arranging function controls for a vehicle, which method provides a control system that is easily converted from a two-hand control for left and right blade lift functions to a one-hand control for the same functions. The method comprises the steps of placing the blade lift levers at the extreme left and right ends of a pivot shaft inserted through the control console, with the third lever for the optional functional control placed adjacent to the right blade lift lever; and placing the left and right blade lift control valves at opposite ends of the control valve stack similarly to the placement of the left and right control levers, with the optional functional control valve placed adjacent to the right blade lift control valve as with the optional control lever. The hydraulic fittings for the left blade lift function valve and the optional functional control valve are reversible, such that to convert the control pattern from the two-hand pattern to the one-hand pattern for the blade lift levers, the operator merely needs to reverse the hydraulic fittings for the left blade lift function valve and the optional functional control valve. A re-identification of the levers the control valves of which have been reversed is helpful to the operator in utilizing the controls.
