The 40-liter fabric grass box collects clippings efficiently. Thanks to the magnetic deflector, removing and emptying the grass box is quick and easy with one hand.

6. Maintenance
Regular maintenance ensures the longevity and performance of your lawnmower. Always disconnect the battery before performing any maintenance tasks.
- Cleaning: After each use, clean the underside of the mower deck and the grass box. Remove any grass clippings or debris using a brush or cloth. Do not use water jets or high-pressure cleaners.
- Blade Care: Periodically check the cutting blade for sharpness and damage. A dull or damaged blade can affect cutting performance and may need sharpening or replacement.
