ABSTRACT:
A gradual engagement system for use in power equipment is herein described. The gradual engagement system causes a clutch pulley to rotate around a clutch arm when an engagement tensile force is applied by an engagement spring. The engagement spring is attached to a pivot arm which is also connected to the clutch arm. The gradual engagement system allows the clutch arm to be pressed against a drive belt in a gradual fashion, providing for a smooth engagement of the various components of the power equipment.
