Blade Maintenance

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.

indicates that the blade is not properly balanced or has
