Best lawnmower blades for Cub Cadet

If you are struggling to get your lawn looking beautiful, even if you are using the top-range Cub Cadet lawnmower, then the blades you are using are likely the culprit. Sharpening can help you temporarily, but eventually you will need to replace the blades because they grow dull at some point.

Accidents can happen to your Cub Cadet mower that forces the blades out of shape, or the blades become dull as time goes on. When the blades become dull, you are putting excess wear and tear on the motor itself, as the mower needs to work harder to achieve the same result. In addition to that, the fact that the mower is working so hard means that its internal parts are at greater risk of wearing down and permanent damage – and replacing the entire mower is much more expensive compared to replacing the blades.

If you are struggling to find the best blades because of the wide variety of options, you do not need to frustrate yourself over the process anymore, as we have included the best 4 we find in the market.

Note: Since some of these products are unavailable on Amazon, we will link the manufacturer’s websites where applicable.

What to consider when selecting mower blades for your Cub Cadet

So you are probably familiar with all the different types of blades – regardless of whether you are buying for a Cub Cadet or any other lawnmower. You get to hear terms like high-lift, 2-in-1, all-purpose, standard, mulching, and so on – but what do they actually mean?

Before setting out on the quest to choose a lawnmower blade, it always helps to know what type of blade you are looking at. Plenty of mower blades are meant to fulfill three needs – bagging, mulching, or discharging. Some blades will work well towards one function, while others are more versatile.

Types of lawnmower blades

Discharging blades

These are meant to move the clippings of grass or leaves from under the mower deck, and they work best for bagging in fact, these blades are what you see being referred to as ‘Standard’, ‘lifting’, or ‘2-in-1’ blades. Their design incorporates a curve along their edges, and this promotes air flow that allows the blade to pull up the grass as it cuts it.

There are three types of lifting blades – low-lift, medium-lift, and high-lift. The general rule is that you will require more horsepower the higher the lift is. That means that you will use high-lift blades if you are tackling denser or taller grasses, while low-lift blades will work better for low intensity jobs.

In addition to this, it is important to remember that you should avoid using a lifting blade when you want to do mulching.

Mulch blades

The aim of these blades is making the grass clippings disappear, rather than discharging them like discharging blades do. They do this through recirculating the clippings, and then cut these clippings several times. The result is that the clippings are much smaller, and will also decompose at a faster rate.

Due to their functionality, the mulching blades have a longer surface (also curved), and they also have additional cutting notches or surfaces along their edges. These blades are usually referred to as ‘All-Purpose’ or ‘3-in-1’ blades.

While they are deemed as all-purpose blades, the versatility is not always a good thing – there are some drawbacks. One is that your mower will need to work harder to achieve the same result of mowing the grass because the blades have a design that re-circulates airflow.

These blades are also relatively more expensive, because they will come as part of a mulching kit that includes the installation hardware, as well as a plug that cuts the grass into smaller pieces, as well as closing off the discharge opening.

Bagging blades

These are the least common lawnmower blade type, but they are a good investment due to their versatility. They will allow you to mulch the clippings, discharge them, and also bag the clippings.

Tips to choosing the best lawnmower blade

Aside from the type of blade you should consider, there are some additional factors to keep in mind. They are:

Length of the blade

The blade length is very important to think about, as these blades come in a variety of lengths. Most of the premium choices will range from 16 inches to 22 inches, with some being more or slightly less than that.

The number of blades

Not all blade packages will come with one or two blades, so it is important to verify from the seller. If you are finding your preferred blades but they only come in one, you might need to buy a set of 2 or 3, depending on the needs of your mower.

Size of the deck

The lawnmower deck size should also correlate with your lawn, and you also need to choose blades that fit that size accordingly.

Width of the blade

The blade width is another factor that will really depend on the mower type you use, and these widths can vary from 2.25 inches to 3.5 inches. The width will also depend on the purpose of the blade, so ensure you choose wisely.

Final thoughts

It is important to choose a good lawnmower blade for your Cub Cadet mower, and make sure that it fits your grass cutting needs. If you are unsure, you can also refer to your manual to give you some recommendations for blades you can get, as well as answering other questions regarding safety issues.


How often should I change my mower blades?

After inspecting the blades, you can tell if they have any dents or issues. Keep in mind that yard debris can lead to blunting and erosion of the blade, so also check the blade thickness. A good general rule to follow is replacing them annually.

Must the blades be too sharp?

Not really, although they need to be sharp enough to cut the grass – but you should not cut yourself when touching the blade. In addition, blades that are too sharp will also become blunt faster, which results in a shorter blade life.

Can I sharpen both sides of the blade?

When sharpening them, always do so from the cutting edge’s top side, in order to get the longest life without the blade dulling out. Avoid making the blade too sharp as well.
