The improved clutch of the present invention includes a fluid actuated piston in the pressure plate assembly which may selectively and gradually be moved into and out of position to engage and disengaege the clutch plate between the pressure plate assembly and the flywheel. The improved clutch also includes a fluid actuator circuit to control the selective and gradual engagement of the clutch assembly.
