1. Low battery voltage: Ensure that the battery is fully charged and has sufficient voltage. A weak battery may not provide enough power to the electrical system, causing the engine to cut out when the clutch-brake is released.
2. Loose battery connections: Check the battery terminals and ensure they are clean, tight, and free of corrosion. Loose connections can prevent proper power flow and cause intermittent electrical issues.
3. Faulty ignition switch: The ignition switch may be defective or have loose/dirty contacts. Inspect the switch and its wiring for any damage or wear. Clean or replace the switch as needed.
4. Fuel issues: Ensure that there is sufficient fuel in the tank and that the fuel line is free of kinks or blockages. Also check the fuel filter for clogging and replace it if necessary.
5. Safety switches: Check the safety switches, such as the seat switch or clutch-brake safety switch, to make sure they are properly engaged and functioning correctly. Clean or adjust these switches if required.
6. Electrical connections: Inspect the electrical connections throughout the mower, paying particular attention to any loose, damaged, or corroded wires or connectors. Clean and repair any faulty connections as necessary.
7. Electrical components: If the above steps don't resolve the issue, there could be a problem with one of the electrical components, such as the ignition coil, voltage regulator, or starter solenoid. It's recommended to have the mower inspected by a qualified technician for further diagnosis and repair.
Before attempting any repairs, refer to the owner's manual and follow all safety precautions to avoid injury or further damage to the mower.
