Also question is, how do you remove a blade from a lawn mower?
To remove the blade, you must turn the blade's retaining bolt to the left, or counterclockwise. Before undoing the blade, tip the mower on its side with the engine air cleaner facing up and block the blade with a piece of wood so it can't turn.
Hereof, how do you remove the blade from a Briggs and Stratton lawn mower?
Use a piece of wood to deep the blade from rotating. Remove the bolt (B, Figure 21) that holds the blade. Briggs & Stratton engines that are used on walk behind lawnmowers use a right hand thread and would be loosened by turning counter-clockwise with a 9/16" wrench.
Well as indicated earlier, most mower blades will last about 20-25 hours until they should be sharpened. But in terms of overall lifetime, most blades last at least 100-200 hours total, and some higher quality ones can last even longer, as much as 400 hours.
