Lawn Mower Blade Features and Considerations
Here are the features to consider when looking for the best lawn mower blades:
Type of Blade
Essentially, there are five types of lawn mower blades, each with its distinct features and benefits. Determining the best lawn mower blades for you becomes easy once you understand their differences.
Most walk behind lawn mowers today are sold with standard medium-lift mower blades. Compared to low-lift blades, medium-lift blades are bigger in size and are capable of doing more.
These might include plucking thicker grass and some weeds in both residential and commercial settings. While the blade is stronger, it does not eat your grass harshly as a high-lift blade would.
These lawn mower blades have a slight upward angle at the back to create an airflow pattern. That works well for typical side grass ejection.
Medium lift blades are perfect for high efficiency cutting of large grass areas. They will leave small clumps of grass here and there. Since the blades do not create an adequate lift to propel debris through the chute and bag, the chute on the bagger system is more likely to clog than that of a mower using a using a high-lift blade.
Also known as regular blades, 2-in-1 blades or basic blades, high-lift blades are ideal for mowers with a bagger.
High lift lawn mower blades can be easily recognized by a bigger and drastic upward angle on its back end. They create an entirely different airflow pattern that bags clippings more effectively. This also helps at propelling clippings through the chute and to the mower bag, thus reducing clogging.
A high-lift blade would be ideal if you have fast-growing and thick grass. It lifts more in one go and clears out most grass clippings from your yard. These blades can work for longer periods of time, are stronger, and are suitable for commercial use.
As opposed to walk behind mowers, riding lawn mowers use high-lift blades. Due to the mower’s longer discharge chute, the blades often have bigger “wind wings” that create more airflow under the offcuts.
Low lift mowing blades are mainly meant for side discharge mowing and are a common choice for people mowing terrain with sandy soils and dry, shorter grasses. Basic walk behind mowers commonly feature these.
The airflow from low-lift blades is not as forceful as that of high-lift blades. This results in lesser sanction and a less drastic swoop that collects a lower amount of debris and airborne dust.
Keeping up with a low lift blade is not hard, and they do not consume as much energy as medium or high-powered blades.
Low-lift lawn mower blades are suitable for residential use and are rare to find on professional-grade lawn mowers. They can effectively handle lesser space and less wild grass.
Commonly known as all-purpose blades, mulching blades are designed with a curved surface to allow working in three ways.
Here’s how a this type of blade works:
- it starts by pulling grass in and cutting it, like all blades do
- cut clippings are then sucked inside the mower deck and chopped into tiny pieces
- after this, the innermost curve of the blade releases air pressure to blow the small grass clippings out
Some professionals tout the environmental aspects that are gained, since smaller, re-cut grass clippings can be left on the lawn to decompose and later offer nutrients to the lawn.
On the downside, this style of blade does not propel the clippings through the chute as strongly as a high-lift blade can. If the grass is too long (over four inches), it might not be very effective at recirculating and re-cutting grass into smaller clippings.
Mulching blades are a popular choice for people who mow their lawns without a bagger. They offer a lot flexibility though, and are also easy to use with a bagger.
Gator or 3-in-1
For an all-rounded solution, gator lawn mower blades cover all the bases. The blade combines a low and high lift with a mulching feature. This helps blend the three grass cutting techniques into one and is hence referred to as a 3-in-1 blade.
You can easily spot gator blades. They have serrated sections at one end of the blade.
While these blades make higher lift mulching possible through their all-inclusive design, they do make compromises in other areas. Nonetheless, the gator blade is popular and suitable for all-around grass cutting.
Mulching Blades vs. Regular Blades
Regular blades are referred to as 2-in-1 since they cut and release grass clippings through the chute, or fling the pieces into a collection bag.
On the other hand, mulching blades (3-in-1 blades) can handle three tasks – discharge or bag clippings, chip them into mulch, and dispense them on the ground.
Below are the critical differences in the features of a mulching blade vs regular mower blade.
The main feature that distinguishes mulching focused blades from regular blades is the shape. They come in a more curved profile compared to regular blades. With this, they are likely to have longer cutting edges than a regular blade.
This design difference allows this style of blade to keep grass clippings circulating under its deck, and as a result, the clippings are cut repeatedly into smaller pieces.
Regular blades, especially the high-lift blades, are made to generate an aerodynamic lift which pulls grass pieces up and hurls them via the mower’s chute for discharge.
Conversely, mulching blades create a circular air stream to direct grass clippings back towards the blade for more cutting. This is in contrast with the one-directional lift of a regular blade.
A mulching blade is designed to keep grass offcuts under the deck, as opposed to sending them out immediately. As a result, the blades aren’t as effective in bagging or discharging as regular mowing blades.
On the other hand, regular blades don’t chop grass into smaller pieces. Therefore, they don’t function well on mulching lawn mowers, or on the mowers that have mulching kits installed.
While regular mowers are efficient at collecting grass clippings, the insufficiently cut clippings can clog regular mowing blades and the mower’s deck underside.
Get the Right Model Number
To get the right blade size for your lawn mower, you will need to locate your mower’s model number.
Be aware not to confuse the lawn mower model number with its engine model number as these are entirely different. The mower number will make it easier for you to identify the correct blade and other accessories such as brake cable or belt. The engine number will help you locate the right air filter, carburetor, or muffler.
After knowing your model number, it will be easy for you to shop for any type of blade you want for your mower.
Get the Right Mount
A mount is an important feature to remember when getting a replacement lawn mower blade.
Mounting is usually at the center hole of the blade and can come in two different shapes. Since both of them are star-shaped, you might be tempted to overlook their importance. However, getting the wrong hole shape could make your blade useless.
Here is what to look for when examining your mount:
- A one-star shaped mount that comes with five points, which is common on newer lawn mowers
- A one-star shaped mount that comes with six points, which is more common in older mowers
How Often Should You Replace Your Lawn Mower Blade?
This mainly depends on your frequency and extent of your mowing. A homeowner may only need to replace their blade once after every one or two years. On the other hand, commercial landscapers might need to change their blades after a few days or once a week.
Checking if the cut of a blade of grass is clean is the best reference. An unclean cut calls for blade sharpening or replacement.
It is also crucial that you keep checking your blade edge for sharpness and damage. If your blade was damaged by hitting something in the grass, you might need a quick replacement.
A good rule of thumb is having two or more sets of mower blades. This way, you will always have a sharp blade when needed.
The best lawn mower blades are those that make your lawn look neat and beautiful. Regardless of the blade you choose, be sure to sharpen it often depending on your extent of use. A dull mulching blade will have a hard time at cutting grass clippings, and this could leave clumps of grass in your lawn.
