How to Change the Blades on a Cub Cadet Ultima

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.

Reinstall both belt covers and then reinstall the access panel and bolt. Reconnect the spark plug wires and start your Cub Cadet mower.

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.

How to Clean a Lawn Mower Deck

How to Clean a Lawn Mower Deck

Keeping the underside of your Cub Cadet lawn mower clean plays a huge role in the performance of the machine. Grass clippings and other debris cling to the underside of the lawn mower each time you mow, affecting airflow under the deck. Clean your mower deck soon after you’re done mowing. Don’t wait until grass clippings dry and become difficult to remove. Here’s how to clean a  lawn mower deck.

Before performing any maintenance on your Cub Cadet lawn mower, refer to your owner’s manual for maintenance instructions and safety information. Maintenance instructions vary by model, so depending on your lawn mower model our instructions may vary slightly.

Some Cub Cadet mowers have washout ports that make cleaning the bottom of the deck easy. If your mower has a washout port, park the machine on a flat, paved surface and lower the cutting height to the cutting setting. Remove the bag and attach a garden hose to the washout port.

Turn the hose on, start the lawn mower engine and stand behind the machine while you engage the mower blades. Run the mower until no more clippings come out from under the lawn mower deck. When the deck is completely clean, stop the lawn mower engine, shut off the garden hose, and disconnect it from the washout port.

Start the engine again, and stand behind the mower while engaging the mower blades.  Engage the blades for a few minutes to dry off the underside of the mower.

If your mower does not have a washout port, you can still clean the mower deck. Park the machine on a flat surface, shut off the engine, and lower the cutting height. Use your garden hose and aim it in front of the right rear wheel, right in the pavement.

Wait a few seconds then top the hose and engage the mower blades. Run the machine until no more clippings disperse from underneath the mower. Once you’re completely done with the garden hose, run the mower again for a few minutes to dry the underside of the deck.

You can also clean the lawn mower deck by scraping the underside. To scrape the underside of your mower, use a scraper or putty knife.

Make sure the engine is off and all moving parts have stopped before you begin scraping the deck. When you tip the mower on its side to access the underside of the deck, make sure the air filter side is up. This will prevent oil from flowing into the air filter and carburetor, which will prevent your mower from running.

Note: never use a pressure washer to clean your lawn mower deck. The pressure washer can force water into important areas of the mower that should not get wet.
