Proper maintenance of your tines will extend their lifespan and ensure consistent dethatcher performance.
- Cleaning: After each use, remove any grass, debris, or soil accumulated on the tines. Use a stiff brush or cloth. Ensure the battery is removed before cleaning.
- Inspection: Regularly inspect the tines for signs of wear, bending, or breakage. Replace any damaged tines promptly to maintain dethatcher balance and effectiveness.
