Cub Cadets represent one of the best-selling brands of riding mowers on the market, but they require simple maintenance to keep your lawn looking pristine. If you notice an uneven or ragged look to your freshly cut grass, it's time to remove the blades on your Cub Cadet and replace them with sharpened blades. With the right tools, the process of removing the blades should take about 15 minutes.
Remove the ignition key and disconnect the spark plug wire to prevent the possibility of the mower accidentally starting while you are removing the blades.
Disconnect the mowing deck from beneath your mower, following the multi-step directions in your operator's manual. Turn the deck over to provide access to the blades.
Put on your work gloves to protect your hands from accidental contact with sharp edges on the blades. Secure the blade you intend to remove first by wedging wood against it to stop it from rotating.
Use a 1 1/8-inch wrench to remove the hex flange nut from the spindle assembly, rotating the nut in a counterclockwise manner. Set the nut aside and pull the blade off of its spindle. Repeat the removal process for the mower's second blade.
