Like other lawn mowers, as you use your Exmark mower, its blades will slowly get dull from cutting your lawn. Recognize a dull blade by looking at the quality of the cut on your lawn. Dull blades will rip and shred the grass and you will see shredded, brown grass tips a few days after mowing the lawn. This allows disease and fungus to enter the grass easier than if you cut the lawn with a sharp blade. You must remove the blade to sharpen or replace it, and you can complete this task quickly with a few tools.
Stop the engine and wait for all the moving parts on the Exmark mower to stop. Remove the key from the ignition.
Adjust the cutting height to the 5-inch level by using the cutting-height adjustment lever on the mower. Lift the front of the unit and support with jack stands.
Wedge a block of wood between the lawn mower blade and the front or rear baffles.
Use an adjustable wrench or socket wrench to loosen the bolt that holds the blade on the engine shaft.
Unscrew the bolt by hand once it is loose. Set aside the bolt and spring disk washer. The blade should then come right off.
