The lawn mower is designed and intended exclusively for cutting grass in garden areas (and not on other types of terrain). The surface must be level, free from irregularities, stones, or other solid objects, and covered with maintained lawn grass (therefore, not uncultivated or spontaneous vegetation). Grass should be cut regularly and must not be allowed to grow beyond 25–30 cm, as most lawn mowers are no longer capable of cutting at this height. Slopes exceeding 15% (equivalent to 9°) must be avoided, except when using 4x4 models.
For heavier-duty tasks involving spontaneous vegetation, grass taller than the above-mentioned limits, or rougher surfaces than a garden, please consider alternative product categories such as Petrol Flail Mowers or Brush Cutters.
Furthermore, grass must only be cut when both the lawn and the underlying soil are completely dry. Mowing should be carried out exclusively in dry weather, well away from periods of rain or irrigation, and preferably in the afternoon, when the grass is no longer affected by morning humidity. Wet grass tends to bend under the blades, which reduces cutting efficiency, increases the risk of clogging inside the deck, and subjects the engine to excessive strain.
