Abstract:
An apparatus for coupling a work implement to a stick assembly, comprising:a hook member defined in said stick assembly, said hook member defining a recess;an implement pin secured to said work implement, said implement pin being positionable between (1) a first pin position in which said implement pin is located within said recess, and (2) a second pin position in which said implement pin is spaced apart from said recess;an over-center spring which is positionable between (1) a first spring position in which said over-center spring biases said implement pin into said first pin position, and (2) a second spring position in which said over-center spring allows said implement pin to advance between said first pin position and said second pin position; andan actuator which moves said over-center spring between said first spring position and said second spring position.
