Removing, sharpening or replacing your Dixon mower's blades is an important part of its maintenance. Ideally, sharpen your blades after every 3 hours of use. And when you re-affix the blades on the mower, secure the blades with 60 pounds of torque. Or else, the blade may come off during use and cause injury to you or damage the mower. However, tightly screwing the nut on means that it will likely be tough to get off--especially if the mower has been in storage for a while.
Disable the mower by pulling out the spark plug. It will be located on the top of your mower on the right hand side. Simply grasp it with your fingers and pull it out. If you are still unsure of its location or how to identify it, refer to your owner's manual as different models differ slightly.
Turn the mower (carefully) onto its right side.
Immobilize the blade. The best way to do this is to wedge a 2-by-4 between the blade and the bottom of the mower. Since you removed the spark plug, the blade will not move, which makes this a perfectly safe way to immobilize the Dixon mower's blades.
Apply a few drops of penetrating oil directly at the base of the nut. Allow the oil to penetrate for 15 minutes.
Use a long-handle wrench to loosen the nut. The long handle will give you more torque and make it easier to remove the nut.
Remove the blade by pulling it off of the bolt with your hand.
