An automatic clutch offers a level of implement overload protection not possible with other types of clutches. The compact, efficient design disconnects the power source from the drivetrain when overload occurs, and does not reconnect until the speed is reduced. During disengagement, the patented design minimizes damaging torque spikes and heat.
