Starting problems and safety interlocks
Symptoms
- Mower will not start even with charged battery.

- Blade brake shoes can stick if dirty. Clean and test. If defective, replace per manual.
Real-world note
- I found a stuck brake lever once after winter storage. A quick clean restored normal start behavior.

Simple checks
- Inspect quick-connects and plugs for corrosion.
- Wiggle connectors while powered off to test tightness.
- Check fuses and resettable breakers.
When to use a multimeter
- Test continuity in suspect wires.
- Measure battery voltage at the mower under load.
- If you are unsure, get a pro to avoid voiding warranty.
Experience tip
- A loose connector under the deck caused a hard-to-find intermittent cutout. Re-seating it fixed the issue.
Troubleshooting flowchart (step-by-step)
