ABSTRACT:
Apparatuses and methods are provided for preventing damage to a lawnmower engine and crankshaft when the lawnmower cutting blade encounters an obstructive object. A cutting device for a lawnmower is provided and can include an elongate base member, at least one cutting element pivotably attached to the elongate base member, and a biasing mechanism that engages the cutting element and elongate base member. The at least one cutting element can include a blade portion and a drive engagement portion. The cutting element can pivot when the blade portion strikes an obstructive object such that the blade portion absorbs the impact and retracts to form a blunt shape to prevent damage to the cutting element. The pivoting of the cutting element causes the drive engagement portion to disengage from the crankshaft of the lawnmower to prevent damage thereto.
