You’ve probably seen a lot of lawn mowers with a single blade, but have you ever wondered if you could use two blades instead? Well, the answer is yes, you can put two blades on a lawn mower.
However, before you rush out to buy a second blade, it’s important to consider the pros and cons of using two blades on your mower.
On the one hand, using two blades can potentially increase the cutting power of your lawn mower, resulting in a more efficient and effective mowing experience.
Additionally, two blades may be able to handle thicker grass and weeds more easily, which can save you time and effort in the long run.
The problem is that two blades will also put more strain on your mower’s engine, which could lead to longer wear and tear. It can also be more difficult to balance and maintain two blades properly.
The pros and cons of using two blades on a lawn mower, plus tips for installation and maintenance, are covered in this article.
Pros of Using Two Blades on a Lawn Mower
You’ll definitely want to consider using two blades on your lawn mower as it can provide numerous advantages for achieving a well-manicured lawn.
One of the biggest benefits of using two blades is improved cutting efficiency. With two blades working together, you’ll be able to cut through the grass more quickly and with greater precision.
This means that you’ll be able to cover more ground in less time, and your lawn will look much better as a result.
Another advantage of using two blades is that it can provide mulching benefits. When you use two blades, the grass clippings will be cut into smaller pieces, which makes them easier to decompose. This can help to improve the health of your lawn by returning vital nutrients to the soil.
Additionally, mulching can help to reduce the amount of water you need to use on your lawn, which can save you money in the long run.
Cons of Using Two Blades on a Lawn Mower
Using two blades on a lawn mower may result in less efficiency and more fuel consumption. A study conducted by the University of Illinois found that using a single blade is more effective at cutting grass.
This is because two blades on a lawn mower can cause the engine to work harder, resulting in more fuel consumption and decreased efficiency.
Additionally, if the blades are not equally sharp or of the same size, they can cause uneven cutting, leaving patches of grass uncut. Blade sharpness and blade size are important factors to consider when using two blades on a lawn mower.
If one blade is dull or damaged, it can result in uneven cutting and an overall poor lawn appearance.
Alternatives to Using Two Blades
There’s a better way to achieve a perfectly trimmed lawn without sacrificing efficiency and fuel consumption. Instead of using two blades, you can try mulching or bagging your grass clippings.
Mulching involves finely cutting the grass into small pieces, which are then left on the lawn to decompose and provide natural nutrients. Bagging, on the other hand, collects the clippings in a bag attached to the mower and can be used as compost or disposed of.
When deciding between mulching and bagging, consider the needs of your lawn. Mulching can benefit the health of your lawn by providing nutrients and retaining moisture, but it may not be suitable for heavily overgrown lawns.
Bagging, on the other hand, provides a cleaner look and is better for lawns with excess debris or weeds.
Additionally, it’s important to keep your mower blades sharp to ensure a clean cut and promote healthy lawn growth. Dull blades can tear grass rather than cutting it, leading to an uneven and unhealthy lawn.
How to Install Two Blades on a Lawn Mower
Don’t miss out on the opportunity to upgrade your lawn care routine with the installation of two additional blades on your mower. However, before you go ahead with this modification, you need to ensure that your mower is compatible with two blades.
Some mowers are not designed to handle more than one blade, and attempting to install two blades on such a mower can damage its engine or transmission. Therefore, it’s important to check your mower’s manual or consult with a professional before proceeding with the installation.
Assuming your mower is compatible with two blades, the next step is to install them properly. First, ensure that the blades are sharp and in good condition. Dull or damaged blades can affect the quality of your lawn’s cut and cause undue stress on your mower’s engine.
If the blades need sharpening, use a file or a grinder to sharpen the edges evenly. Once the blades are sharp, remove the old blade and carefully install the two new blades, making sure they are in the correct position and securely fastened.
Tips for Maintaining Your Lawn Mower Blades
To keep your mower’s cutting power at its best, it’s essential to regularly sharpen and maintain the blades. The frequency of sharpening depends on the blade material and how often you use your mower.
For example, if you have a soft steel blade, you might need to sharpen it every 10 hours of use. But if you have a hard steel or carbide blade, you might only need to sharpen it every 25 hours of use.
When sharpening your blades, it’s important to use the right tools and techniques. A file or sharpening stone can be used to sharpen the blade’s edge, but it’s also important to balance the blade to ensure it spins evenly.
You can do this by using a blade balancer or by hanging the blade on a nail and checking to see if it tilts to one side.
Frequently Asked Questions

Closing
While two blades may seem like a great idea for a cleaner cut and increased speed, it’s important to consider the potential downsides such as increased wear and tear on your mower and uneven cutting.
