How do you sharpen tiller tines?

To sharpen tiller tines, first, ensure the tiller is turned off and disconnected from power. Use a metal file or angle grinder to carefully sharpen the edges of the tines, maintaining the original angle for optimal performance. Clean any debris or rust from the tines afterward, and apply a light coat of oil to protect them from future corrosion. Regular maintenance will help enhance the tiller's efficiency and extend its lifespan.
