Hey there, if your lawn tractor or mower won't start, this ignition switch might be exactly what you need! This 4-position, 7-terminal switch with a 5/8-inch mounting stem fits tons of popular brands including Husqvarna, Murray, MTD, Craftsman, and Briggs & Stratton models. It replaces part numbers like 140301, 925-1717, 5412, and several others - so definitely check your old switch before ordering. The magneto ignition type works perfectly for most small engines, and it comes with two keys so you've got a spare. Installation is pretty straightforward if you're comfortable with basic wiring - just match up the terminals and you're good to go. This isn't some cheap knockoff either - it's built to handle the vibration and weather exposure that outdoor equipment deals with. Whether your current switch is completely dead or just getting flaky, this direct replacement will have your mower starting reliably again. No more jiggling keys or mysterious electrical issues - just solid starting performance season after season!
