Step-by-Step Guide to Changing Your Cub Cadet Lawn Mower Blades
1. Disconnecting the Spark Plug
This is the first and most important safety step. Locate the spark plug wire, usually a black or red wire, and pull it off the spark plug. You can use a tool like a spark plug wrench to help with this.
2. Removing the Old Blades
- Locate the Blade Bolt: The blade bolt is located in the center of the blade, typically secured with a large nut.
- Loosen the Bolt: Use the socket wrench to loosen the blade bolt. You may need to hold the blade nut in place with a wrench to prevent it from spinning.
- Remove the Blade: Once the bolt is loosened, carefully remove the blade from the mower deck.
3. Installing the New Blades
- Choose the Right Blades: Refer to your owner’s manual to determine the correct blade size and type for your Cub Cadet model.
- Align the Blades: Ensure that the blade holes align with the shaft and the blade is properly seated.
- Tighten the Bolt: Using the socket wrench, tighten the blade bolt securely, but avoid over-tightening.
4. Reconnecting the Spark Plug
After installing the new blades, reconnect the spark plug wire to the spark plug.
Sharpening Your New Blades
While not strictly necessary, sharpening your new blades is a crucial step in maintaining optimal cutting performance.
Sharpening Techniques:
- File Sharpening: This method involves using a file to sharpen the blades along the cutting edge.
- Sharpening Steel: A sharpening steel is a specialized tool designed for sharpening lawn mower blades.
- Professional Sharpening: If you prefer, you can take your blades to a professional for sharpening.
Sharpening Tips:
- Remove the Blades: To sharpen the blades effectively, it’s best to remove them from the mower.
- Maintain Angle: Maintain the original bevel angle of the blade for optimal cutting performance.
- Balance: After sharpening, ensure the blades are balanced to prevent vibration and damage to the mower.
Important Considerations for Your Cub Cadet
Blade Types:
Cub Cadet models can utilize various blade types, each designed for specific grass types and mowing conditions.
- Mulching Blades: These blades create a fine mulch by chopping the grass into small particles that are then returned to the lawn as fertilizer.
- High-Lift Blades: Designed for efficient grass collection, these blades lift the grass higher for a cleaner cut and easier bagging.
- Standard Blades: These blades are suitable for general-purpose mowing.
Replacing the Blade Washer:
It’s advisable to replace the blade washer with each new blade change. The washer helps prevent the blade from loosening and can become worn over time.
Proper Blade Maintenance:
Regularly inspecting and sharpening your blades will contribute to optimal cutting performance and extend the lifespan of your Cub Cadet lawn mower.

Changing lawn mower blades on your Cub Cadet is a simple maintenance task that can significantly enhance the quality of your cut. By following these steps and prioritizing safety, you can confidently replace your blades and enjoy a lush, well-maintained lawn. Remember, regular blade maintenance is essential for a smoothly operating lawnmower and a beautiful lawn!
FAQ
Q1: What tools do I need to change my Cub Cadet lawn mower blades?
You’ll need a few basic tools to change your Cub Cadet lawn mower blades. These include a socket wrench that fits the blade bolt size, a torque wrench, a pair of work gloves, and safety glasses. You might also want to have a blade balancer on hand to ensure the new blades are balanced and won’t cause vibrations while mowing.
It’s important to gather all the necessary tools before you begin the blade change. Having everything ready will make the process much smoother and more efficient.
Q2: How often should I change my Cub Cadet lawn mower blades?
The frequency of changing your Cub Cadet lawn mower blades depends on the frequency of use and the type of grass you’re mowing. As a general rule of thumb, it’s a good idea to inspect your blades every 25 hours of use or at the beginning of each mowing season. If you notice any nicks, bends, or dullness in the blades, they should be replaced.
Sharpening your blades can extend their lifespan, but eventually, they will need to be replaced entirely for optimal performance.
Q3: Can I sharpen my Cub Cadet lawn mower blades instead of replacing them?
Yes, you can sharpen your Cub Cadet lawn mower blades instead of replacing them. This is a more affordable option, and it can extend the life of your blades. However, sharpening is only a temporary solution, and you will eventually need to replace the blades when they become too worn or damaged.
To sharpen your blades, you can use a file or a sharpening stone. Make sure to wear safety glasses and gloves while sharpening, and be careful not to damage the blade.
Q4: How do I safely remove the old blades from my Cub Cadet lawn mower?
Before you start, make sure to disconnect the spark plug to prevent accidental starts. Then, tilt the mower onto its side so that the blades are facing up. Next, use your socket wrench to loosen the blade bolt. Once the bolt is loose, remove it completely and use your gloves to carefully remove the blades.
Remember to keep your fingers clear of the sharp blades as you remove them.
Q5: How do I install the new blades on my Cub Cadet lawn mower?
The installation process is the reverse of the removal process. First, make sure that the new blades are installed with the cutting edge facing down. Then, align the blade bolt with the mounting hole in the blade, and use your socket wrench to tighten the bolt securely.
Use your torque wrench to tighten the bolt to the manufacturer’s specifications. This will ensure that the blade is securely attached and that the bolt is not over-tightened.
Q6: What do I do with the old blades after removing them?
It’s important to dispose of the old blades properly. You can recycle them at a local scrap metal yard or dispose of them in accordance with your local waste disposal regulations. Never throw them in the trash, as they can be a safety hazard.
Make sure to dispose of the blades in a way that is safe for both you and the environment.
Q7: How can I tell if my Cub Cadet lawn mower blades are balanced?
If your new lawn mower blades are not balanced, they can cause vibrations while mowing. This can lead to damage to the mower itself, and it can also be uncomfortable to operate. To check for balance, you can use a blade balancer tool.
If the blades are not balanced, you can adjust them by adding or removing weight until they are properly balanced. You can also purchase pre-balanced blades to avoid this step altogether.
