And it worked!. Well i have a low end Home cheapo 21" homeowners mower. It has worked fine for what i need it for. However all i used it for was mulching around flower beds and stuff in small gated yards. nice stripe nice look no big deal. However i wanted to make it more quick instead of a snails pace especially since we have gotten a ton of rain recently. I decided to take the blade and take 1/2 off each side making a total of 1 inch off the blade. Didn't really know what would happen but figured that 1 inch could make it bog down less. Well it turns out I can basically run with the mower (not really but much more quickly then before) and there is 0 clippings in all types of grass. my 2 cents. rob.
