A dull mower blade doesn't cut grass blades--it tears them, leaving the grass vulnerable to disease or damage from the sun. How often the mower blade needs sharpening depends on the size of your lawn and how often you mow, but plan on doing the job at least every four to six weeks.

on 6/4/2007 When reattaching newly sharpened blade, be sure to use a wrench that will allow you to rotate it outside the bottom of the mower deck. This will prevent any potential injury in case the wrench slips off while tightening the bolts. If you need to, use an extension of some sort - a metal pipe is always useful in this case.
(I didn't do this recently and managed to severely cut by thumb and index finger on the sharpened blade.)

on 8/8/2006 The bolt likely loosens in the standard, counter-clockwise direction.
This may not be good for the shaft, but to loosen a really stuck bolt, you can try this: use a rag to hold a closed end wrench onto the bolt tightly, then hit the other end of the wrench with a hammer to start it.
