Wheel spike add-on for robot lawn mower

These bolt-on spiked traction rings are designed to improve the grip of your robotic lawn mower — especially on wet grass, soft soil, or sloped terrain.

Originally designed for a Parkside mower, but may fit other models with similar wheel sizes, or use scale. Mounting requires screws (not included); I used regular wood screws, which bite well into the rubber tire and hold the spikes firmly in place.

You can mount the rings on the inner or outer side of the wheel. I placed one ring on the inside for the wheel that runs over pavement. The other is mounted on the outside for easier cleaning access.

Note: spikes will wear down if they constantly run on paving stones or gravel. My PETG version lasted ~2 months, even under heavy use on a steep slope.

✅ Improves traction and mower reliability
✅ Easy to print – no supports needed
