🚨 Cub Cadet XT1 Engine runs fine but mower dies the second the blades are engaged
Top Culprit: Failed safety reverse switch or corroded PTO wiring
Why It Happens: Water or debris corrodes the safety switch linkage near the transmission pedal or the electric PTO connector, tricking the machine into an unsafe shutdown mode.
🛠️ The 60-Second Diagnostic Test
- Check under the frame to ensure the reverse safety switch plunger is making full physical contact when the pedals are neutral.
- Unplug the PTO wire harness and use a multimeter to check for continuity across the switch terminals while pulled out.
💡 The Quick Fix Steps
- Clean corroded terminals with electrical contact cleaner, or unbolt and replace the failed reverse safety switch plunger.
- Replug the harness securely, engage the blades on a dry surface, and verify the safety logic resets correctly.
