A joystick for manually operating a pair of hydraulic valve members has a bracket to which a handle is attached. A pivot shaft rotationally extends between a pair of legs of the bracket and has a transverse aperture through which a pivot pin attaches the pivot shaft to a base of the joystick. This attachment structure allows the bracket to pivot with respect to the base about two orthogonal axes. A first link for coupling to one hydraulic valve member is pivotally attached to the pivot shaft, while a second link for coupling to another hydraulic valve member is attached by a ball joint to the bracket.
