Suitable for cordless electric lawn tools, garden mowers, etc. The size is 64 x 20 mm, which fits closely to the blade part of the lawn mower, effectively preventing debris from entering the machine, protecting internal parts from damage, while reducing noise and vibration, and improving operating comfort. Made of plastic material, it has excellent resistance to wear and impact resistance, and can effectively resist damage caused by collisions, friction, or weather factors (such as rain and sun) in daily use, and extend the service life of the lawn mower blade. As a safety shield for the blade, the green plastic cover can effectively prevent users from being injured by accidental contact, increase operational safety, and is especially suitable for use in occasions such as home maintenance and gardening. The eye-catching green appearance is not only beautiful and easy to identify in the lawn or garden, but can also serve as a warning to a certain extent.
