Is your John Deere lawn tractor with a Briggs & Stratton engine just clicking and not turning over? The starter motor might have given up. This is a brand new replacement starter designed for John Deere riding mowers and lawn tractors equipped with Briggs & Stratton engines in the 16, 18, 20, and 22 horsepower range. It's a direct replacement for the original starter. Brand is Celox. Part number is AB139875746AD. It comes with a 90-day warranty. Includes the standard California Prop 65 warning. Number in pack: 1 (just the starter). Type: Starter. No UPC. This is a critical component - when you turn the key, this electric motor spins the engine's flywheel to start it. If yours is dead, you'll often hear just a single click from the solenoid. Replacing a starter is a common DIY repair for handy homeowners. You'll typically need to disconnect the battery, remove a couple of bolts, and disconnect the wiring harness from the old starter, then reverse the process with this new one. Always double-check your specific John Deere model number and engine HP before ordering to ensure compatibility. Get your mower starting reliably again and avoid those frustrating push-starts. A quality part for a common fix. Don't let a bad starter keep your yard work from getting done.
