摘要： An engine starting system that includes a power source (320), an electromagnetic coil (330) and core (335), and a choke valve (340) disposed in an air intake of an air/fuel-mixing device of an internal combustion engine. At the time of starting the engine, the power source outputs an electrical signal to an electromagnetic coil and core, inducing a magnetic field from the electromagnetic coil and the core. The magnetic field from the core moves the choke valve toward a substantially closed position that enriches an intake mixture of fuel and air to the engine during starting. In one embodiment, the power source includes a moving magnet (325) that interacts with a stator coil to provide the electrical signal to the electromagnetic coil. In another embodiment, the closing of a starter switch allows a battery to provide the electrical power to the electromagnetic coil.

摘要： The improved battery-powered lawnmower includes a safety key (48) that is automatically removed when the removable battery (22) is removed, while at the same time blocking the battery recharger receptacle. The lawnmower also includes a control circuit that shuts off the lawnmower upon the occurrence of one or more of several predetermined conditions, including low battery voltage, the encountering of heavy grass for a period of 3 seconds or more, and high motor current that may occur when the cutting blade is jammed. The cutting blade (264) is designed to move through any debris accumulated between the blade ends and the housing sidewall (284) without sacrificing the lift for needed cutting and mulching. The invention also includes a unique height adjustment assembly for adjusting the height of the chassis, a handle attachment that allows the handle to be positively tightened to the lawnmower chassis, and a telescoping groove (76) for the battery's quick connect/disconnect terminals.
