Importance of a Sharp Lawn Mower Blade
Sharp mower blades are all that stand between a healthy, well-maintained lawn and an unhealthy one. A sharp blade can cut down on the damage to the grass by being clean, while dull blades cause a more destructive effect. A blade that doesn’t cut cleanly leaves the grass with ragged edges that can turn brown and make it susceptible to disease or pest infestation. Research shows that dull blades demand about 40% more work from the mower, damaging the equipment, and using more fuel or energy.
Certainly, the blade is an on-the-job time saver and resource saver, especially if it is sharpened often or replaced from time to time. They say a blade must be sharpened every 25 hours or at least twice during the season to ensure it functions at its best. Sharp blades promote healthier grass by allowing it to grow evenly and putting the plants under less stress, besides giving the landscape that neat look.
