Changing the blades on your Dixon mower is an important part of its maintenance. Every two to three hours of use, take off your mower's blades to sharpen them. While they are in the vice, it is the perfect time to inspect the blades. Once you spot any deep nicks that cannot be filed off, excessive wear or bends in the blade, it is time to change the blades on your mower.
Pull out the mower's spark plug with your fingers. It is located on the right side of the mower near the engine. If you are unsure how to identify it, refer to your owner's manual.
Turn the mower on its side so that the air filter is facing up. The air filter sits just below your engine and looks like a series of slits from the outside.
Stop the blade from turning. You can do this by having a helper (wearing work gloves) hold the blade still while you work. Or, simply wedge a 2-by-4 between the blade and the bottom of the Dixon mower. (If you choose the second mathod, keep your hands a safe distance away from the blade.)
Remove the nut with a long-handle wrench.
Place the new blade on the bolt. Thread the bolt through the hole in the center of the blade. Rest it on the thrash guard so that it is in the same position as the old one was in before you detached it.
Tighten the nut. Use a torque wrench to apply 60 foot-pounds of torque. Any less and the blade may come off during use.
Right the mower and replace the spark plug.
