Abstract
In a control for use in a hydraulic system of the type which includes a hydraulic cylinder arranged to raise and lower a load such as a dump bed of a vehicle, wherein the hydraulic system is actuated for raising and lowering the dump bed upon axial displacement of a rod member contained within an outer conduit from a neutral position in first and second respective axial directions and wherein the hydraulic system is deactivated upon the rod member being in the neutral position. The control includes a tubular member which is adapted to be connected to the outer conduit, a control knob, and a rigid inner member partially within the tubular member having a first end connected to the rod member and a second end supporting the control knob. A latch supported by the tubular member is arranged for releasably locking the inner member in a neutral position with respect to the tubular member for precluding inadvertent axial displacement of the rod member from the neutral position.
