How to Change the Blades on a Cub Cadet Ultima

Over time, the blades on your Cub Cadet Ultima zero turn rider can become worn out or dinged. The gradual damage of the mower blades can reduce the effectiveness of your mower. Check the blades on your mower at least twice a year, at the beginning and middle of the mowing season. Check the blades more often if you mow more frequently. Here’s how to change the blades on a Cub Cadet Ultima.

Before performing any maintenance on your Cub Cadet Ultima, refer to your operator’s manual. It lists required maintenance, safety information, and instructions for your machine. Maintenance instructions vary by model, so depending on your model our instructions may vary slightly.

Begin by parking your zero turn on a flat, level surface. Turn the engine off and allow it to cool, remove the ignition key, disconnect the spark plug ignition wire to prevent accidental starting, and engage the parking brake.

Set the deck height on your Ultima to the lowest setting. Use a 3/8-inch socket or wrench to remove both belt covers from the deck.

Remove the access panel. Use the panel access tool included on Cub Cadet Ultima mowers to remove the bolt from the panel.

Remove the belt from the spindle pulleys. Use a 9/16-inch socket or wrench to pull the idler pulley arm back to release the belt tension.

Remove the belt from the idler pulleys and PTO clutch. Use both a 9/16-inch socket and wrench to loosen the idler pulley bolts.

Remove the cotter pins and deck pins from the deck. Slide the deck out from under your Cub Cadet mower. Flip the deck over to access the blades. Wear gloves for protection when working with blades.

Remove the blades. Use a block of wood and wedge it between the blade and the frame of your machine to stop the blades from rotating. Use a 15/16-inch socket or wrench to loosen the blade nuts.

Replace the blades on your Ultima and tighten the nuts. Make sure the word “bottom” or the blade part number is facing the ground when installing the blades.

Flip the deck over and slide the deck back into place under the mower. Reattach the deck and slide the deck pins back into place. Reconnect the cotter pins.

Reinstall the belt. Route the belt around the PTO clutch. Route the belt through the idler pulleys.

Use both a 9/16-inch socket and wrench to tighten both idler pulley bolts. Route the belt around the spindle pulleys. Use a 9/16-inch socket or wrench to release the tension and finish routing the belt.

Troubleshooting Tips for Cub Cadet Lawn Mowers

Troubleshooting Tips for Cub Cadet Lawn Mowers

If you want your Cub Cadet lawn mower to work effectively each time you start it, there are certain maintenance steps to take to ensure your machine is in great condition. Maximize the life of your mower with these troubleshooting tips.

Tip #1 – Keep up with routine maintenance

Stay on top of routine maintenance. This will increase the performance and life span of your Cub Cadet lawn mower. Your lawn mower is most likely the most frequently used piece of outdoor power equipment so perform the proper maintenance to maximize life and efficiency.

Tip #2 – Check spark plugs and carburetors

Clogged air filters, fouled spark plugs, and flooded carburetors are common problems that can affect the starting and performance of your Cub Cadet lawn mower.

Replacing the spark plug can make a huge difference in the performance of your mower. To combat a flooded carburetor, you need to drain the carburetor and put new fuel in it.

Tip #3 – Utilize new fuel and air filters

Fresh fuel and a clean air filter will help prevent lawn mower problems. Use fresh, mid-grade fuel with no higher than E10 Ethanol rating, stored in a clean, sealed container.

To clean your air filter, tap it to remove loose dirt and debris. Hold your filter to the light. If you see the light, the air filter is okay to use. If there is no light, replace the old air filter with a new one.

Tip #4 – Keep a sharp lawn mower blade

Look at the blade on your Cub Cadet lawn mower. Dull lawn mower blades trim grass unevenly and leave the tips of your grass torn and not cleanly sliced.

Tip #5 – Check bolts, wheels, cables and belts

Tighten all bolts on your Cub Cadet lawn mower and check to make sure that the wheels, cables and belts are not overly worn. This can cause problems when mowing.
