5.Inspect the Blade for sharpness and wear, especially where the flat and the curved parts meet (Fig. 26A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the lawn mower. If you notice a slot or wear (Fig. 26B and 26C), replace the blade.
