When removing and installing lawn mower blades after sharpening or replacing, two areas need special safety precautions. One is to always remember to put safety stands under the deck after raising or jacking it up (see photo), and the other is to be careful not to cut your hands when handling and installing the blades. Always place a board between the blade and deck when tightening so the blade won’t have a chance to turn. Taking a few minutes to do these two things, and putting on a good pair of gloves is also a good idea.
