To keep your Dixon mower running smoothly, you should remove its blades after every few hours of mowing. Lawn mower blades need regular sharpening or they leave jagged grass ends which are susceptible to disease. And, when sharpening your lawn mower blades, check for damage that signals it is time to replace the blades. To sharpen or replace the blades at your leisure, keep an extra blade or two on hand.
Turn the Dixon mower's engine on. Push it outside and allow it to run until all of the gasoline has been drained from the tank.
Pull the spark plug out with your fingers. If you are unfamiliar with its location on your machine, consult your owner's manual.
Turn the mower onto its side.
Keep the blade from moving by holding one side of it while wearing a thick leather work glove.
Use a long handle wrench to remove the nut in the center of the lawn mower blade that affixes it to the bolt.
Pull the blade off the bolt carefully with your hands.
