What kind of lawn mower are you changing blades on?
The best lawn mower blades for mowing quality is the cylinder mower, ideal for fine lawns and sports turf.
You can lift a riding lawn mower with a car or floor jack in order to change the blades. Simply place the jack under the frame of the lawn mower but away from the blades to lift it. Then, block the mower up using bricks or concrete blocks.
The blades are dull when the grass is not getting cut effectively. This is evident when after passing over an area there remain patches of uncut grass. Also you may find some increased resistance, especially if you are using a simple push mower.
If your push lawn mower is not working as well as it used to work, you might be thinking about replacing it. Before you purchase a new push lawn mower, check your current mower's blade. Over time, lawn mower blades grow dull and no longer cut grass as effectively. If you take your lawn mower blade to a hardware store that offers a blade sharpening service, you can usually get the blade resharpened for a small fee. With a newly sharpened blade, your old lawn mower could be working just like new.

To sharpen lawn mower blades, carefully unscrew the blades from the machine. Use a putty knife to scape off any residue. Then take a medium file and stroke the edge of the blade evenly.
Most blade bolts on lawn mowers are reverse threaded. The bolts on the Craftsman brand lawn mower are also reversed.
