Kohler Command 17.5 starter probles

I have 2002 John Deere Saber with a 17.5 Kohler that has been running with out may problems until recently. Here's what happening. I shut of the motor went to restart it and nothing.... After pushing it back to the garage, I tried again and nothing. so I removed the battery to charge it and the charge indicated a bad cell. Replace the battery with a fully charge new one, still nothing. replaced the solenoid and still again nothing but a few clicks. Next step seeing the first two failed was replace the starter with a matching part number. Turned on the key and the starter Bendix gear just spun and did not draw up to engage the flywheel.  Thinking I may have a bad ground or connection I removed all connections and cleaned them. reconnected all, turned the key and the Bendix gear just spun and  din not engage. has anybody had such a problem and if so what was the correction?

If you're experiencing starter problems with a Kohler Command 17.5 engine, it can be frustrating, but there are several troubleshooting steps you can take to identify and potentially resolve the issue. Here's a guide to help you diagnose and address starter problems:
1. Check the Battery:

• Ensure that the battery connected to the engine is fully charged and in good condition. Weak or dead batteries can prevent the starter from turning the engine.

2. Inspect Battery Connections:

• Examine the battery terminals and cable connections for corrosion, looseness, or damage. Clean and tighten the connections if necessary.

3. Test the Solenoid:

• The starter solenoid is responsible for engaging the starter motor. Use a multimeter to test the solenoid for continuity. If it's malfunctioning, replace it.

4. Check Wiring and Connections:

• Inspect the wiring from the battery to the starter motor and the solenoid for frayed wires, loose connections, or damaged insulation. Repair or replace any faulty wiring.

5. Starter Motor Inspection:

• The starter motor itself may be the problem. Check for visible damage or signs of wear. If it's damaged or worn, you may need to replace it.

6. Lubricate Moving Parts:

• Some starter systems have moving parts that require lubrication. Ensure that all moving components are properly lubricated to reduce friction.

7. Test the Ignition Switch:

• Use a multimeter to test the ignition switch for continuity. If the switch is faulty, it may not send the signal to engage the starter motor.

8. Check the Safety Switches:

• Many lawn mowers and small engines have safety switches (seat switch, blade engagement switch, etc.) that must be engaged for the starter to work. Make sure these switches are in their correct positions.

9. Inspect the Flywheel and Gear Teeth:

• Examine the flywheel and the gear teeth on the starter motor for any damage or wear. Damaged gear teeth can prevent the starter from engaging with the flywheel properly.

10. Compression Check: - If the engine has very high compression, it can make it more difficult for the starter motor to turn the engine. Perform a compression check to ensure the engine's compression levels are within the specified range.
11. Professional Assistance: - If you've checked all the above components and are still experiencing starter problems, consider seeking professional help from a small engine mechanic or service center. They can diagnose more complex issues and perform any necessary repairs or replacements.
Remember to follow safety precautions and disconnect the battery before conducting any electrical or mechanical work on the engine. Additionally, consult the Kohler engine manual for specific troubleshooting and maintenance instructions for your Command 17.5 engine model.
