Possible Causes

Perimeter wire buried too deep or broken, Base station signal too weak, Faulty perimeter receiver in mower, Strong interference from other systems

How to Fix / Troubleshooting

Safety first: Turn OFF the mower before adjusting the perimeter wire.

  • Check wire depth: Ensure the perimeter wire is at the recommended depth (usually on the surface or shallowly pegged). Deep burial can weaken the signal.
  • Inspect for breaks: Walk the perimeter and look for damage. Repair any cuts with proper connectors.
  • Verify base station operation: Confirm the base station LED indicates a healthy perimeter signal.
  • Reduce interference: Keep the perimeter wire away from other buried cables and metal fences where possible.
  • Test with small loop: Create a small test loop and see if the mower respects the boundary. If it still crosses, the perimeter receiver in the mower may be faulty.
