Abstract of the Disclosure An apparatus for controlling the position of an operating handle includes a plate for coupling an operating handle to a positionable device such as a hydraulic valve. The plate includes a detent notch. An auxiliary lever is movable between a first, engaged position and a second, disengaged position and is maintained in either position by a compression spring which exhibits toggling movement as the lever is moved between positions. The lever includes means for engaging the detent notch when the lever is in the first position and the handle is thereby retained in a predetermined position. The apparatus is especially useful on agricultural tractors which tow implements having hydraulically operated functions. In addition to permitting retention of the operating handle in the neutral position, the apparatus can also retain the handle in an operating position and, in cooperation with a stop mechanism, also permits handle movement to a float position for positioning implements or decelerating high inertia loads.
