By now your lawn should be in full swing, healthy and green. But, if it develops a strange brown dried-out appearance after mowing, the culprit just might be a dull lawnmower blade.

A dull blade rips and tears the grass tips instead of cutting them, so within hours they begin drying out and turning brown. This also creates an opening for all kinds of disease.

Keeping your mower blade sharp is the solution, but because many newer blades have complex cutting surfaces, it may be best to have a pro sharpen them.

If you choose to do the job yourself, you can clamp the blade in a vise and sharpen it with a file or use a bench grinder. Repeat this chore after every 10 to 12 hours of mowing, and you can be sure that your yard will keep looking sharp.
