What To Consider When Buying A Lawn Mower Blade
When choosing the best lawn mower blades, it is best to consider the type of lawnmower with regard to its deck and power capacity. Some lawnmower blades require more power to operate efficiently with the lawnmower motor.
When deciding on the best lawn mower blade, remember that the best part about the blade is that it can compensate the motor power of the machine with its sharp edge. So this means that even though your motor might not help increase the speed of the cut, you can still have a better cut just by choosing a blade with a certain length and sharpness.
1. The Length Of The Blade
There is no science to this however it is important to note that longer does not mean better. The length decided on should fit within your lawnmower’s model. Most blades range between 16.75 inches and 22 inches. Most mowers are compatible with blades that are as long as 22 inches. However, remember it’s all based on your model. If the blade’s length is too short, it won’t cut as wide of an area but at the same time, if it’s too wide, it won’t fit.
2. Build Material
The build material of the blade is not dependent on the model of the mower. The best choice is strong stainless steel. Lower metal can help you cut costs but it is highly unlikely that it will cut your grass.
Keep in mind that picking your lawn mower blade set is very important as it can really influence your life. You want to pick a blade that will actually do the job you’re seeking it to do. Remember to also look at the paint job on the blade as this will help you tell if it will rust easily.
3. The Deck Size
The deck size is the final consideration you make when choosing lawn mower blades. Most push mowers have a deck size that ranges from 16 to 30 inches. Riding mowers have higher sized decks as well.
4. Blade Width
The typical width of most mower blades ranges between 2.25 and 3.5 inches. However, like we said earlier, its important to pick a blade that is compatible with your machine. A blade that is too wide might not fit and can end up damaging the lawnmower. On the other hand, a shallow blade might not cut well. The best thing to do is check your lawnmower’s manual for further advice on the required width.
5. Total Number Of Blades
If you have a riding lawn mower, you’ll have to consider the total number of blades. However some handheld mowers do require multiple blade settings though more often than not, they just need one single blade. If you have a riding mower, it would be ideal to buy a lawn mower blade set that will match the width of your deck. Most self–propelled and push mowers only need one blade.
Types Of Lawn Mower Blades
1. Standard Lift Blades
Standard lift blades are generally used in standard lawn mowers and tend to be the ones that rotate horizontally. They are also often referred to as straight more blades even though they tend to have a slight curve on each end. You’ll often find them on lawn mowers that discharge grass debris sideways. The slight bend at the ends allows a bit of air ventilation through. This creates a sort of suction of the land as it pulls the grass up so that it can be cut precisely.
When choosing this blade, it is best to keep in mind that what matters most is the type of the land you are mowing on. This blade is preferred by most because of its high efficiency on both dry and damp grounds. However, standard blades are better suited for yards with thick patches of grass as they can rapidly cut dense grass and send it to the bagging with ease.
The downside of standard blades is that they are not able to remove the smaller patches of grass hence your yard is left looking uneven. This is not the right blade if your ground is full of light grass.
2. Medium Blades
Medium blades are slightly curved hence the suction created is minimal. It is enough to straighten grass for trimming but not enough to send the debris through the chute and into the bag. As a result, the debris builds up and eventually blocks the chute which ends up restricting the debris from being stored into the bagging. The clogging can also cause your lawn mower to stop functioning.
3. Low Lift Blades
Low lift blades are best for grounds that have dry, shorter grass or if your ground has sandy soil. The airflow from a low lift blade is not as forceful as that from a high lift blade hence it results in less suction and also reduces the amount of airborne dust and debris. They don't require a lot of power to function hence allowing for silent and effective mowing. The downside of low lift blades is that it can often clog the chute as its unable to suck the debris into the bagging.
4. High Lift Mower Blades
High lift blades tend to have specific vertical angles on the edges. These enable maximum airflow through the blades and produce a vertical suction. The fast circular motion of the blades ensures the grass is taut and perfectly trimmed. If you’re looking for utmost precision while mowing, high lift blades will help you achieve that fresh precise look.
The high level of suction ensures that there is no accumulation of grass in the chute hence preventing blockage. Those that prefer bagging tend to prefer these blades. High level blades don’t work well with sandy grounds due to the maximized airflow. Hence the blades tend to suck in the sand and dust along with the grass and this in turn can damage the deck of the lawn mower as it wears off easily.
Additionally, the rapid and continuous spinning of the blades requires more power and this can actually damage your mower earlier than expected.
High lift blades are designed to cut the grass and lift the clippings by propelling them up and out the discharge chute. Riding lawn mowers tend to use high lift blades but mostly because of the longer discharge chute. The blades often have to have larger “wind wing” to create more airflow under the clippings.
5. Mulching Blades
Mulching blades work best if you want to replenish the soul using the grass debris. They are mostly used in push or riding lawn mowers. Mulching blades are considered to be multipurpose and are commonly referred to as 3-in-1 blades.
Their edges of mulching blades are curvier and more distinct. They have more cutting edges than other blades hence enabling them to cut the grass into smaller, finer pieces before discharging them back to the ground.
Mulching blades however are not suited for dense long patches of grass and if used for that, can actually cause the deck to clog up. Its advised that the grass should not be longer than 4 inches if you want to use a mulching blade. Mulching blades should always be kept sharp as a dull blade will give you hard time as it will struggle to re-cut the grass clippings and instead result in clamps of grass being left on your own.
Mulching blades allow you to fertilize your soil while also ensuring that your lawn is neat.
6. Gator Blades
Gator blades are ideal if you want your soil to be fertilized. They are modified to achieve a better result. The blades are designed to create maximum suction on the grass which pulls it upwards. The gator mower blade acts as a secondary blade that pulls the grass upwards in way that allows all the grass to be cut precisely.
The gator blade has a unique angle that continually pushes the grass towards the sharp cutting edge as the mower keeps moving. As a result, the smaller pieces of grass are further cut into even smaller pieces. If you’re looking for a better result, you can attach a mulcher blade hence the mulching blade will distribute the small and fine pieces of grass allowing them to settle on the ground uniformly.
How to sharpen lawn mower blades
It is recommended to sharpen your blade at least once a year.
Though dull blades can still cut grass, the difference between a sharp and dull blade is that the latter will roughly rip through the grass leaving behind raggedly torn tips on the ends of the grass blades. That can in turn cause your grass to turn yellow/brown leaving your lawn to be more susceptible to pests and diseases. Sharp blades cut grass quickly, precisely and allow for a trimmed and healthier lawn.
Hence, it is ideal to sharpen your blade at the beginning of the mowing season. If your blade has interacted with the ground or hit rocks, it is recommended to sharpen it again midway through the mowing season.
There are different ways to sharpen a lawnmower’s blade. Some of the common ones are using a hand file, rotary tool, angle grinder or a bench grinder. The most efficient way is using a drill and sharpening stone that is specifically designed for putting a cutting edge back onto dull lawnmower blades,
1. Clamp and File
A flat file can be used to sharpen a dull blade. The first thing is to ensure that the blade is secured in a vice. Then you apply pressure to file and run it perpendicular to the edge of the blade to grind down and smoothen the imperfections in the metal. This will allow you to hone the shape of the existing edge. Once this is done, reposition the blade do the same on the other side. The process might be slow but it works.
2. Using a Bench Grinder
Using a bench grinder is one of the fastest ways of sharpening a lawnmower blade. It is necessary that when embarking on this venture that you are well equipped. You should be in protective eyewear, ear plugs and work gloves as you grind the edge of the blade against the spinning wheel. A bench grinder is also ideal for repairing a heavily damaged blade that is riddled with gouges that are hard to file smooth by hand.
3. Use a Drill and Blade Sharpening Stone
A blade sharpening drill operates similarly to a bench grinder but on smaller and more affordable scale. It is faster than hand filing and the stone is designed to hug the edge of the lawn more bald hence reducing the room for error while making it easy to sharpen.

- The next step is to empty the lawn mower’s fuel tank. This is done by turning the lawn mower upside down so that you can access the blades and clean them. Emptying the tank ensures that there is no risk of fuel spilling out from the tank. You can either ran the tank dry or use a hand pump siphon to extract all the fuel.
- The third step is to remove the spark plug wire from the spark plug as you will be rinsing your lawn mower hence you don’t want to risk any chances of current running though. This will also keep you safe from the lawn mower accidentally going on while cleaning the blades. For some lawn mowers, the spark plug is removed using a wench while others the spark plug wire is pulled upwards.
- Use a hose to spray down the blade with the aim of getting rid of all the debris and grass. It is best to use a hose with a relatively high pressure steam as it will push off the accumulated grass. You can lay the lawn mower on its side and keep spraying it till most of the grass and debris has washed off.
- Use a brush ideally a stiff bristled one to clean the blades thus getting rid of all the areas that the hose failed to reach.
- Once the blades are clean, remove them from the lawn mower and from the housing using a ratchet set. It will take some serious force hence its is advised to use a long handled wrench.
- Wipe the blade and housing using a thin layer of vegetable oil before re-attaching to the blade. The oil will help prevent debris from accumulating on the blade and housing quickly later on.
Ultimately choosing the best lawn mower blade depends on your needs. Its best to do your research to ensure that you are buying a blade that is compatible with your lawn mower. The worst thing would be to jeopardize both your lawn mower and grass.
