Maintenance Tips

  1. Cleaning After Use: After each use, remove soil, mud, and debris from the tines and body of the tiller. This prevents buildup that can hinder performance and cause corrosion over time.
  2. Check the Tines: Inspect the tilling blades for damage or excessive wear. If the blades are dull or damaged, replace them to maintain efficient tilling. Ensure they are securely attached and tightened before each use.
  3. Inspect for Loose Parts: Regularly check for any loose screws, bolts, or fittings and tighten them as needed. Vibrations from the tiller’s operation can cause parts to loosen over time.
  4. Lubrication: Apply lubricant to moving parts, such as the tines and any other pivot points, to ensure smooth operation and to prevent rust.
  5. Cord Care: If your tiller has a power cord, inspect it for any signs of wear, fraying, or damage before and after use. Use a proper outdoor-rated extension cord and store it coiled neatly, away from sharp objects.
