Abstract: An apparatus and method for starting an engine comprising a frame and an internal combustion engine operatively mounted to the frame. A control member is operatively connected to the frame, wherein the control member has an activated position and a deactivated position. The control member is adapted to complete an engine circuit when in the activated position. An energy storage medium is operatively associated with the engine such that release of energy stored in the energy storage medium turns the engine and facilitates its starting. A starting assembly is utilized to release the stored energy in the energy storage medium. An operator must utilize two separate and distinct actions, activating the control member and activating the starting assembly, to restart the internal combustion engine.

Abstract: A modular engine design system utilizes selectively replaceable components whereby a family of related engines having varying power outputs may be produced. A first series of engines utilizes a common piston operable in a cylinder of first predetermined dimensions. The engine design may utilize a first or second crankshaft/connecting rod combination to vary the power output. A modified engine design utilizes a second cylinder in addition to the first cylinder. A second series of engines utilizes a larger piston operable in a cylinder of second predetermined dimensions. The second series of engines shares a common engine design scheme with the first series of engines. However, corresponding parts are adapted for use with the larger piston/cylinder combination. The second series of engines may likewise utilize a first or second crankshaft/connecting rod combination to vary the power output. Within each series of engines, modular design concepts are utilized to provide a range of power outputs.

Abstract: An illumination mechanism includes a plurality of LEDs for illuminating a surface and is configured to determine whether one of the plurality of LEDs has faulted. A pair of LED sets is provided with the sets electrically connected in parallel via terminal connections of each set of LEDs. Regardless of at least one of environmental temperature or minor differences in minimum forward voltages of individual LEDs, the mechanism is configured to discern whether at least a single LED of one set of LEDs of the pair has faulted. In instances where the sets of LEDs are separated from a controller or voltage measurement circuitry, the cost, real estate consumption, and manufacturing complexity associated with additional wiring and connections are minimized.

Abstract: A lawn maintenance vehicle includes an adjustable seat assembly, wherein the seat assembly is rotatable relative to a frame of the vehicle when the vehicle is operated on a sloped surface. The seat assembly is rotatable in order to maintain the operator in a substantially vertical seated alignment while operating the vehicle on a sloped surface. The seat assembly is also rotatable when the vehicle is in a zero-turn or tight-turn maneuver, wherein the seat is rotated toward the center of turning radius to offset the centrifugal forces experienced by the operator during such a maneuver.
