Lewisville Lawn Mowing ServicesLawn Mowers: Need to be cleaned and mower blades sharpened. Carefully remove lawn mower blades and wash with water and a couple of tablespoons of Clorox to remove any diseases carried over from last year. Take your blade to a local lawn service shop to have it professional sharpened. This will allow your lawn mower to work more effectively. If you have not had your lawn mower serviced recently this would be the time for a tune up to extend the life of your lawn mower.
