ABSTRACT:
A crankshaft impact protector for protecting the crankshaft of a lawnmower engine from bending beyond its elastic limit whenever a hard or immovable object like a rock or a stump is struck by the lawnmower blade. The protector has a flange for mounting on a mower deck, a mounting base for mounting the lawnmower engine thereupon and a bumper for providing physical support to the crankshaft. Impact forces experienced by the crankshaft are dissipated by the bumper of the protector and shifting of the bumper with respect to the crankshaft is prevented because the engine is integral with the crankshaft impact protector. A small clearance is provided between the bumper and the crankshaft thereby also helping to prevent soil and dust from traveling therethrough and reaching the main bearing of the engine.
