One other thing I forgot to mention is that one of the best things you can do is hand sharpen your mower blades... I did both of mine and from the factory they are dull compared to a decent edge... I noticed that my blades are "mulching blades" in that they have a rise and dip to chop up the cut grass into mulch and I can say that feature works amazingly well once the blades are sharpened. With a factory edge it didn't seem to mulch much... Night and day difference with a sharp mower blade.
