Grezuton 12V 1.1KW Starter Motor 10-Tooth CW — Direct-Fit for Kohler & Lawn Mowers (2509808/41012182R)

Grezuton 10-tooth clockwise starter motor, 12V 1.1KW, designed as a direct-fit replacement for Kohler and many mower brands listed by the OEM part numbers.

This compact starter motor is manufactured to match the form, fit and function of the original equipment for a wide range of small engines. Built to the listed replacement numbers and tested for reliable engagement, it supplies the torque and rotation direction required for many Kohler engine models and equivalent aftermarket applications from John Deere, Toro, Cub Cadet, Scotts and others. The unit features a 10-tooth drive, clockwise rotation and a 1.1KW power rating for consistent starts in typical lawn and garden machinery.

Will this starter fit my engine and how do I confirm compatibility?

Compatibility depends on the exact engine model and the OEM part numbers the engine requires. Check the part numbers stamped on your original starter or consult your engine's service manual to match one of the listed replacement numbers. If you’re uncertain, compare tooth count, rotation direction and mounting bolt pattern before ordering.

• Match one of the replacement numbers: e.g., 2509808, 2509809, 2509811, 41012182R, SDR0291.
• Verify 10 teeth on the starter pinion and clockwise (CW) rotation.
• Confirm 12V electrical system and similar mounting flange pattern.

How does this starter perform compared with OEM parts?

This Grezuton starter is built to meet or exceed OEM specifications using modern manufacturing and quality control processes. It’s tested for engagement reliability and durability under typical mower use, offering a practical alternative when OEM parts are unavailable or costly. Performance aims to replicate factory starting behavior, including consistent cranking speed and engagement.

• Designed to match OEM torque and engagement characteristics.
• Constructed from quality materials to resist wear and heat.
• Inspected and tested to reduce premature failure risk.

What are the key specifications and what do they mean for everyday use?

The starter runs on 12 volts and delivers about 1.1 kilowatts of power, enough for reliable cranking on typical small-engine mower applications. Its 10-tooth pinion and clockwise rotation must match the engine’s flywheel ring gear and rotation direction. Correct electrical and mechanical fitment ensures quick, repeatable starts during mowing and yard work.

• 12V system compatibility — fits standard lawn tractor battery setups.
• 1.1KW power rating — adequate starting power for small engines.
• 10-tooth, CW pinion — matches flywheel gear and rotation of listed engines.

Who is this for: This starter is intended for owners, repair shops, and maintenance crews working on lawn tractors, garden tractors and small engine equipment that require a 10-tooth clockwise starter with 12V electrical systems. It’s a good option for anyone needing a cost-effective, tested replacement for Kohler OEM numbers (such as 2509808, 2509809, 2509811) and equivalent part references across John Deere, Toro, Cub Cadet, Scotts, Thomas and Grasshopper equipment. If you maintain multiple machines or replace starters seasonally, confirm the tooth count, rotation and mounting pattern to ensure a trouble-free swap.
