How do I know if the mower blade on my MJ401C-XR needs to be replaced?

IMPORTANT: The mower blade is sharp and can cause severe personal injury if handled incorrectly. Wrap the blade or wear protective gloves, and use extra caution when handling.

The steel blade is designed to provide a fine cut in long or tough grass. Deterioration in the quality of cut indicates blade wear or damage.

Follow these steps to determine if the blade needs to be resharpened or replaced:

  1. Disconnect the power supply to the mower by removing the safety key.
  2. Turn the mower on its side to expose the underside of the blade housing.
  3. Check the blade.
    • If the blade is blunt or has minor wear, then resharpen. Contact an authorized Snow Joe® Sun Joe® service center.
    • If the blade shows signs of major wear or damage (i.e. gouged, bent), replace. Please call Snow Joe® Sun Joe® customer service for assistance at: 1-866-SNOWJOE (1-866-766-9563).
