Abstract
A lawnmower engine cutoff system interrupts the electrical flow to the ignition system of an engine when a predetermined weight of clippings is contained within the catch bag for grass clippings. Mechanical movement is generated by the weight of the grass clippings contained in the catch bag. This movement is then sent to a switch in the ignition system of the engine. When the movement reaches a predetermined level, the switch in the electrical system of the engine is opened and the engine ceases operation.
