🚨 Toro TimeCutter Engine dies instantly when brake is released or arms moved
Top Culprit: Faulty safety interlock switch
Why It Happens: A failed seat or control-arm interlock switch can falsely signal an unsafe operating condition and shut the engine off.
🛠️ The 60-Second Diagnostic Test
- Inspect the seat and control-arm safety switches for loose connectors, damaged wiring, or switches that are not being mechanically actuated.
- With the engine off, use a multimeter to test each switch according to the Toro wiring diagram without bypassing the safety circuit.
💡 The Quick Fix Steps
- Replace the safety switch that fails the specified continuity test.
- Reconnect all wiring and verify the mower shuts down and operates correctly under the factory safety logic.
