Robot mower stops with blades off but wheels still trying to move, often on steep slopes.

Safety first: Avoid working on steep slopes; turn OFF the mower before handling.

Steps to check:

• Reduce slope area: Adjust the boundary wire to exclude the steepest parts of the lawn.
• Improve traction: Clean mud and grass from wheel treads. Replace wheels if the tread is worn smooth.
• Schedule dry mowing: Run the mower when the grass is dry to improve grip.
• Remove excess weight: If heavy accessories are installed, consider removing them when mowing steep areas.

When to call a technician: If one wheel consistently slips more than the other, the drive motor or gearbox may be weak and need replacement.
