Aumtoni Kohler Engine Starter for 15–31HP (1994–2015) — 12V CCW 10‑Tooth Direct-Fit Replacement

Aumtoni's 12V CCW 10-tooth starter is a direct-fit replacement for many Kohler 15–31 HP engines made 1994–2015, engineered to revive cranking power on mowers and small tractors.

This heavy-duty starter is built as an aftermarket replacement for Kohler-engine machines used by John Deere Cub, Toro, Scotts, Thomas, Cadet, and Grasshopper brands. It matches the common OEM spec for 12-volt, counterclockwise rotation and a 10-tooth drive, so you can swap it in quickly when your original unit fails. The package ships with one starter and carries a customer-friendly return policy if there are issues.

Will this starter fit my Kohler engine and garden machine?

Yes — the unit is manufactured to suit Kohler engine models produced between 1994 and 2015 with output ratings from 15 to 31 horsepower. It targets widely used lawn and utility equipment, so compatibility is high when your engine matches the listed specs. Double-check engine model and part numbers before ordering.

How does the starter connect and turn the engine over?

The starter operates on a 12-volt electrical system and turns counterclockwise (CCW), engaging the flywheel via a 10-tooth drive gear. That match of rotation and tooth count ensures correct meshing with Kohler flywheels designed for these engines. Wiring follows standard starter hookup conventions on small engines.

• 12-volt electrical system suitable for most lawn equipment batteries
• Counterclockwise rotation (CCW) matches OEM orientation
• 10-tooth drive gear for proper flywheel engagement
• Standard starter terminals for inline installation

What should I expect when installing this replacement starter?

Installation is typically straightforward for anyone familiar with small-engine maintenance: disconnect the battery, remove the old starter, mount the new unit, and reconnect wiring. Because this item is designed as a direct replacement for the listed part numbers, mechanical fit and electrical connections normally align with the original hardware. If you lack experience, consult a service manual or technician.

• Disconnect battery before starting work for safety
• Swap old starter for new; bolt pattern and shaft should align
• Reconnect wiring—observe polarity and secure terminals
• Test cranking before reassembling machine covers
