Sharpening Mower Blades

The mild temperatures and moderate rainfall makes tall fescue thrive during the spring. We aerate and seed during the fall to repair any areas and help with soil compaction to provide better pore space allowing your lawn to breathe more.

Come spring in our climate, tall fescue is in its second growing season for new plants and numerous seasons for fescue plants that are well established. This also means it’s generating new growth like crazy!!

Spring mowing may often be needed every five days. It is important to not only keep your mower maintained but keep a sharp blade. Often times new mower blades are not sharpened perfect for safety reasons. The easiest way I find to sharpen my blade is a bench grinder. There are many kits you can buy at your hardware store to help you with sharpening and leveling.

Dull Blade

What I find easiest for me is to use the bench grinder to sharpen. To level I simply hammer a nail halfway into something upward and flat and place the center of the blade where it would screw into the mower on the nail. If it sits at a 9 and 3 o’clock level I know it’s good. If one side sits lower than the other that means I need to take a little more off that side to even it out.

The importance to having sharp blades goes beyond aesthetics. When the blade is dull it stresses the plant which also makes it more susceptible to disease. When your blade is dull it makes your mowing have a white appearance and the tip is torn. How often you need to sharpen depends on the size of your lawn and how often you mow. A rule of thumb would be to monitor the up close and far away appearance. If it looks like clean even cut you will know. The pictures included is of the same lawn up close and from a distance.
