Answer: How often you need to replace the blades depends on how frequently and intensively you use the mower—such as the quality of your mowing, how many hours you operate it, and the workload it handles. You can decide based on your own usage, but we officially recommend replacing the blades every 1–2 months.
Note: If any blade is cracked, chipped, bent, or otherwise damaged, replace it immediately. Using a damaged blade can be dangerous and may affect performance or safety.
