Things to Consider Before Buying Cub Cadet Mulching Blade

The right blade can make all the difference in being able to mulch effectively with your lawnmower. If you've decided to buy Cub Cadet Mulching Blades, there are several things to consider before you make your purchase.


The blades are not universal fit, so it's important that you know about their compatibility. You can find this information in the user manual for your mower.

Essentially, you want to ensure the blade will fit your mower's configuration and engine.

Blade Material

The best mulching blades are typically made of carbon steel. They're inexpensive but heavy-duty enough to withstand the beating of the elements and any hidden obstacles (like rocks, toys, etc.).

Besides being wear-resistant, carbon steel blades also hold a finer edge for longer. So, you won't have to sharpen them quite as often as other blades.

Blade Design and Thickness

Some blades have a curved (3-in-1) design that helps eliminate clippings and prevent buildup. Others have a "higher-lift" style (2-in-1)that helps create a higher-lifting airflow.

In general, a cub cadet mulching blade with a curved design is preferable for mulching. It offers an extra cutting surface and increased deck circulation, both of which are required in the mulching process.

The "higher-lift" blade, on the other hand, offers better performance at discharging grass clippings.

Thickness plays an important role as well. A thicker blade will usually provide greater durability and strength but at the cost of maneuverability and speed. A thin blade may not be as strong or as durable. But it will allow your mower to cut faster and more easily through thick grasses like Bermuda or Fescue varieties.

Blade Length

One of the most important things to consider when choosing a mulching blade is its length. This will determine how much grass is cut at once, which affects both cutting quality and efficiency.

You want to ensure that the length of your new blade should match that of the existing one. Otherwise, you may end up cutting out more than half of what was already there!

Essentially, the blade length is determined by the deck size of your Cub Cadet. It is important to note that if your deck has 42 inches, then your blade should have 21 inches in length. Also, if your deck has a size of 48 inches, then your blade should have 24 inches in length.

Number of Pieces

You'll want to make sure you're buying the right number of blades. The number of blades your lawnmower uses varies greatly depending on the model of the mower. Some use one, some use two, and some even use three.

If you have a twin blade setup, for example, it's important to purchase a kit that includes two blades.

Mounting Hole Style

Before you buy a mulching blade for your Cub Cadet, it's important to know what type of mounting hole style you have. There are four types of mounting holes: universal, bow-tie, five-star, and six-star. And choosing the right style ensures that you get a great fit every time.

Universal (round) mounting holes are standard and will fit all Cub Cadet mowers. A bow-tie mounting hole looks just like it sounds: like a bow tie; five- and six-star blades are both star-shaped with five or six points, respectively.

The difference between them is in the way they fit onto your mower deck. So if you're not sure which type of mounting hole style you have, don't worry!

Just take a look under the deck of your mower and see if you can identify one of the following shapes. For instance, if you see a six-pointed star shape, then choose a 6-point star-shaped mulching blade for your machine.


When you're checking out mulching blade options for your Cub Cadet mower, it's important to go with a brand you trust. You want a brand that will be around for a while. Also, it should have a reputation for high quality and great customer service. The best way to get this kind of information is to look at the reviews.

Read customer reviews

Reviews are nice because they give you direct insight into how real people feel about a product. This means that they're not always 100% accurate, but they can be helpful in rounding out the complete picture of what you're getting when you buy the product.

When looking at reviews, try to look at the overall picture instead of just focusing on one or two comments.


If you like what you see in the reviews, consider looking into whether the company offers any guarantees or warranties on their items. This is especially useful if your mower is older and it's been hard to find parts/accessories for it.

If you find something that comes with some kind of guarantee or warranty, then it's less risky to buy. You can return it or get a replacement if something goes wrong with it down the road.

A Guide to Cub Cadet Blade Replacement

Cub Cadet Blade Replacement

If your lawn tractor has been losing power, it may be time to look at the replacement of your blade. This guide is designed to help you in the process of replacing your Cub Cadet lawn mower blades.

How to Change Cub Cadet Mower Blades

How to Change Cub Cadet Mower Blades

Step 1:

The first thing you'll want to do is be sure that the engine is off and the spark plug wire is disconnected.

You'll also want to wait for the mower deck to cool down before completing this process.

Step 2:

Use a ratchet set and socket wrench to remove the drive belt guard so you can access the drive belt.

Step 3:

Disconnect and remove the drive belt by removing it from the engine pulley and clutch pulley. Use a flat head screwdriver to do this if necessary.

Now that you've removed these parts, they'll be out of your way as you work on replacing the blades themselves.

Step 4:

Remove all of the nuts that hold the deck together. These should be located on top of each side of the deck. You may need to use either a ratchet set or a socket wrench.

After removing these nuts, you will have access to the bolts that hold your blades in place.

Step 5:

Remove the bolt with a ratchet set and then slide out each blade one at a time until they are removed completely from the machine.

Step 6:

Finally, install new blades by inserting them into their slots on either side of the deck plate. Tightening down with bolts as needed to the right torque (70-90 foot-pounds of torque for most Cub Cadet Mulch Blades).

Note: You may need some help aligning them properly. So have a leveling gauge handy.

Mulching blades vs High lift blades for Cub Cadet


If you have a Cub Cadet lawnmower, you're probably trying to decide whether mulching blades or high-lift blades are best for your mowing needs.

The truth is, you can use both types of blades on Cub Cadet lawn tractors. However, they are designed to produce different results.

Mulching Blades

Mulching blades or 3-in-1 blades are designed to cut grass into small pieces that can be left on the lawn. The grass then breaks down into organic material that provides nutrients to the soil.

These blades are relatively short and often have a curved, rounded shape to increase cutting surface and deck circulation.

Why a 3-in-1 design? It's because they can mulch, discharge, and bag grass clippings. They're pretty much "all-purpose" mower blades.

However, due to the re-circulating air design, they don't offer as much discharge performance as standard "high-lift" blades.

High-Lift Blades

High-lift blades or 2-in-1 blades, on the other hand, are designed for more versatility in terms of cutting height and ability to discharge clippings.

These blades are typically longer than mulching blades, with a flatter blade surface and less curvature. And as the name says, they lift the grass up from the ground prior to cutting, creating a cleaner cut at the base of the grass blade.

Why the 2-in-1 design? It's because they're not designed for mulching but for discharge and bagging.

Cub Cadet Blade Engage Lever: What to Do?


Of course, you want to know why your Cub Cadet blade engage lever doesn't work! Let's go over some basics for troubleshooting this problem.

  • Check the PTO (power take-off) clutch

The clutch connects the engine to the blades by engaging the drive belt. So, if the clutch is worn out, the blades won't engage. If that's the case, you'll have to replace it.

  • Check the PTO (power take-off) switch

The problem might be due to a faulty switch. So we recommend checking your PTO switch - the switch that turns on your mower's blades.

Check for continuity using a multimeter to determine if it's defective or not. If defective, replace it.


Don't worry; we've got all the answers to your questions in one place. So you can get back to your lawn (or do whatever else makes you happy).

1. Do I need to sharpen my new Cub Cadet blades?

New blades are designed to be sharp and ready to use. So when you buy a new set of blades, you're free to start mowing with them right away.

2. What is the difference between a regular blade and a mulching blade?

A regular blade is designed to cut grass as it comes out of the discharge chute but does not recut it into smaller pieces. A mulching blade cuts the grass into very small pieces and then recuts them over and over again until they are well hidden in the yard.

3. Do Gator blades do a better job than mulching blades?

Gator blades are also mulching blades. But they're a special kind that contains micro-grooves on the blade itself, which cut grass into smaller pieces than regular mulching blades do. Hence, they do a better job of mulching.

4. Can mulching blades side discharge?

Yes, mulching blades have a 3-in-1 multipurpose design. They can mulch, bag, and side discharge grass clippings. However, standard mulching blades tend to push down on the grass - though not by much.

5. At what frequency should I sharpen my mulching blades?

After every 20 to 25 hours of use, the reason for this is simple—mulching blades have to cut grass clippings three times as many times as a normal blade. Because of this, the blades dull quickly and need sharpening more frequently.


And that's it!

These are our top picks for the best mulching blades for Cub Cadet lawnmowers. While this list is by no means exhaustive, we hope you feel empowered to go out and choose the blade that's right for you.

All of these blades are made with Cub Cadet's special blade geometry. So, whether you have an old Cub Cadet or a new one, there's a blade for you. Also, it means that you'll get an excellent cut, no matter what type of mulching blade you choose!
