Patent number: 9488149Abstract: A starting system for outdoor power equipment that has a controller and a start button to control the activation of an internal combustion engine. The starting system includes a controller that receives a start signal from a start button. The controller monitors for the presence of an enable device in an enable device receptacle and, upon activation of the start button and the presence of the enable device in the enable device receptacle, the controller provides electric power to the electric load of the power equipment. When the start button is depressed for longer than a minimum engagement period, the controller initiates operation of the engine. If the start button is pressed for less than the minimum engagement period, the controller activates the electric load for an auxiliary period without starting the engine. During engine operation, if the start button is depressed, the controller terminates operation of the engine.Type: GrantFiled: June 18, 2014Date of Patent: November 8, 2016Assignee: Briggs & Stratton CorporationInventors: Robert J. Koenen, Stephen J. Ryczek, Bruce S. Lydy, Erik R. Slegelis, Steven J. Weber

Publication number: 20110203864Abstract: A hood assembly for a lawn tractor that includes a removable air intake cowl to prevent debris and rain from entering into the open interior defined by the hood. The air intake cowl is removably mounted to the hood of the lawn tractor. The hood of the lawn tractor includes a series of engine intake openings that allow air to flow onto the internal combustion engine. The cowl is defined by a top wall and a pair of depending sidewalls that each include a series of air inlet openings. The air inlet openings extend generally perpendicular to the top panel of the hood and thus prevent debris and rain from reaching the engine intake openings.Type: ApplicationFiled: February 25, 2010Publication date: August 25, 2011Applicant: BRIGGS & STRATTON CORPORATIONInventors: Stephen J.
