It would be a great reality if lawn mower blades were to last indefinitely and you would never need to replace them, but this is not the actual case. They will eventually become blunt, begin to look worse for wear, and wear down the mower itself because it has to use more energy to sustain the same quality of operation.
Thankfully, the negative effects of old and worn-out lawn mower blades do not need to be your reality, because there are many great replacements in the market today. You do not need to wait for them to wear out the mower either, because replacing the machine is much more costly compared to replacing the blades alone.

We will also give you some tips on choosing the best blades for your requirements, and a short rundown of replacing them when that time comes.

Rotary Blades for Husqvarna/Craftsman/Deck – great for larger lawnmowers
This blade is great for a larger lawnmower, especially if you own a Craftsman, Husqvarna, or Poulan model – and any other model for that matter.

However, they are compatible with a limited range of models, especially those of a 48-inch deck, which are quite large.
Since they are strong and very unapologetic when it comes to their performance, they will excel in all tasks you put them to. The only problem is their cost – they are among the more expensive options we have seen in the market.

- Works well with baggers if you want to store clippings for later use

The combination of having very strong design and sharpness makes the Rotary blades a great choice if you want a versatile blade that can handle a variety of tasks. However, you will need to be careful when using and storing them, although their performance offsets the cost they come in.

The blade is quite versatile, and it can be used alongside a variety of lawn mowers because of its star-shaped center mount hole. These mowers include Craftsman, Husqvarna, and Poulan.
Moreover, the long blade that measures 22 inches provides it with a cutting area that is wide enough to handle a variety of sections in your lawn without forcing you to return to the same section. It also helps with cutting a wide area without compromising on your cutting smoothness.
While it is very easy to install and comes in a great design though, it has some struggles with suction because the blade does not transfer the weed clippings strongly into the bag, and the bag also has a clip at its opening that reduces the suction efficiency.
Pro tip though: when connecting the blade to the mower, make sure to use something that locks your old blade in place in order to avoid unnecessary rotation and risk injury. Unbolt it and attach the new blade, bolt it, and then reconnect the spark plug to use it.
- The blade is long enough to cover a wide area

The products we don’t recommend
Greenworks 29373 lawn mower blade – the blade is of low quality
This blade is not a terrible choice, and it is great when you want an easy-to-maintain option, we did not like the fact that the measurements described are not the actual measurements. Its description states that it is a 19-inch blade but it actually measures less than 18 inches, which is quite disappointing and leaves you at risk spending money on it and having it fail to live up to its expectations.
That said, it is quite easy to install and allows you plenty of cutting options, but it tends to also dull quite quickly and the blade blunts faster than we would like it to be. That means you cannot use it for a heavy job, and you are actually better off spending on higher-quality blades.
- Easy to maintain for DIY enthusiasts
- Does not fit the length specifications
- The blade becomes blunt very quickly
This blade is great if you need to do light work, but weeds require much more power, and there are better blades than this one if you need to accomplish the job.
What should you consider when buying mower blades for your weeding?
The type of lawn mower blade
Not all lawn mower blades are the same, contrary to what you may initially assume. There are 2 lawn mower blade types: discharging blades and mulching blades.
For mulching blades, they are in a curved design, and they have numerous cutting surfaces on the edge of the blade. These cutting surfaces denote its sharpness – the more they are, the finer the clippings or debris. Some also refer to mulch as 3-in-1 blades because you can do three functions: mulch the clippings, discharge them from the sides, or bag them.
Since mulching blades are more in demand, that informed our choices above – most of the list is made up of them. Just keep in mind that its results may not live up to your expectations, unless the mower specifically has a certain mulch setting that allows the blades to achieve optimal airflow to disperse and mulch the debris efficiently.
The other type of blade is the discharge blade, which is a mainstay of older mower types, especially the push ones. They will either direct the debris or clippings into a bag, which you dispose later, or discharge the clippings from the sides. You might also see the term ‘high lift’ to refer to them as well, since they raise the clippings throughout the cutting process, which allows you to throw them away easier after you are done.
Tips on choosing the best lawn mower blades
There are some additional things to keep in mind aside from the type of blade, which are:
Length of the blade
Mower blades will range from a minimum of 16.75 inches to a maximum of 22 inches, with most of them either being 21 or 22 inches long. Regardless of the length you select, you need to ensure it fits your mower properly – if it is too wide, it will not fit, and if it is too short, it will not cut much of the area.
Width of the blade
Width is also important to keep in mind, because blades that are too wide will eventually damage it. The range is usually from 2.25 inches (minimum) to 3.5 inches (at the maximum).
Size of your mower deck
This really depends on the specific type of mower you have. The usual push mower will range from 16 inches to a maximum of 30 inches, and the riding lawn mowers will go anywhere higher from that.
The number of blades you have
If you happen to have a self-propelled or push mower, you might only require one blade, while a riding mower will need a number of blades because of its wide deck.
Number of holes in the blades
Certain blades will have a 6-point opening design, while others have a 5-point design. Ensure you check the type of opening your mower can handle, even if the description of the blades is that they can work for multiple mower models. In addition to this, you need to also ensure that the size of this opening is compatible with the mower.
Before spending money on those mower blades, make sure to take a close look at the original blades and see their shape. For instance, are they parallel or perpendicular? What does their shape look like?
Make sure that the blades matches the original as close as possible, in order to achieve the best performance, even if the blades do not exactly match.
If the issue you have is not the price, but you are instead seeking satisfaction and high quality blades, you should go for the MaxPower 331740B blades. They are the easiest to replace, according to our research, and they are also in a heavy-duty design that fits well with most mower brands and types.
