The service life of the blades of a robotic lawnmower depends on several factors, at least some of which you can influence positively. Nevertheless, even with very good care, the blades will dull sooner or later. To ensure that the cutting pattern remains clean, regular replacement of the blades is unavoidable. But how often is this necessary?
Blunt blades have a negative effect in several respects.
The life of the blades of a robotic lawnmower varies significantly. Some factors you can influence, others less so. For example, collecting foreign objects such as fallen fruit, cones or branches and shorter mowing times can significantly extend the service life.
Finally, the type of blade also affects it’s durability. Blade plates - usually three – have significantly thinner blades that are less able to cope with foreign objects than robust blade plates. The interval for replacing the blades is correspondingly more frequent so that the cutting pattern remains nice and clean in the long run. This is usually around 1-3 months for knife plates, while star plates sometimes only need replacing once a season. Keep in mind that star plates are also somewhat more expensive to purchase.
Ultimately, it is advisable to understand the manufacturer's specifications as a guideline and to determine the time for blade replacement based on the cutting pattern of the lawn. Frayed tips are easy to spot and a clear indication of dull blades.
It is not possible to make a blanket statement about how often the blades on the robotic lawnmower need to be replaced, and it also depends on your model. While some manufacturers recommend a monthly change, which can be delayed somewhat by particularly long-lasting blades, it is sufficient to replace the blades in other devices once or twice per season.
Replacement blades are available for each model from the manufacturer and from specialist dealers. Changing them takes only a few minutes and usually requires no more than a screwdriver. The change is even easier with a special click system and the required tool is included in the delivery.
For safety reasons, it is advisable to wear safety gloves when handling the blades. They are similar in sharpness to razors and cause cuts even with a little carelessness.
Even without considering the interval for changing the blades, it is recommended to check them frequently for wear and tear. A good time is certainly when cleaning the mowing deck, which is done regularly anyway.
The manufacturer's specification for replacing the blades is only a guideline. The durability of the blades depends on several factors and it is not possible to make a blanket statement about the correct frequency of blade replacement. It is best to observe the cutting pattern and regularly check the blades for wear in order to determine the ideal time for blade replacement.
