Your lawn mower makes all the difference when it comes to a well-groomed lawn. Two of the most common types of lawn mowers are the 2 blade and 3 blade models. Each type has its own unique advantages and disadvantages, and choosing the right one for your needs can be a daunting task.

Before deciding which type of lawn mower to buy, you need to consider a variety of factors, including the size of your lawn, the type of grass you have, and your budget.

We’re going to discuss the differences between two and three blade lawn mowers, the advantages and disadvantages of each, and how to maintain your lawn mower so it lasts.

By the end of this article, you will have the knowledge you need to make an informed decision about which type of lawn mower is right for you.

Overview of Lawn Mowers

Overview of Lawn Mowers

From the traditional push mower to the more advanced ride-on mowers, choosing the right mower can make a big difference in the overall appearance of your lawn. 

However, with the increasing emphasis on eco-friendly lawn mowing alternatives, it’s important to consider the environmental impact of your lawn mower as well.

One popular debate in the lawn mowing industry is the 2 blade vs 3 blade lawn mower argument. While both types of mowers can effectively cut grass, blade mowers are considered to be more eco-friendly as they require less energy to operate. 

This is because they have a single blade that rotates horizontally, cutting grass in a scissor-like motion.

On the other hand, 3 blade mowers have multiple blades that rotate vertically, which can cause more damage to the grass and require more energy to operate.

Advantages of 2 Blade Lawn Mowers

With a 2 blade mower, you can expect a precise and even cut on your lawn. The two blades work together to create a cleaner cut, which, in turn, allows for a healthier lawn. 

The precision of the cut is important because it allows for the grass to heal faster, reducing the chances of disease and insects infesting your lawn.

Additionally, the evenness of the cut ensures that your lawn looks symmetrical and beautiful. When comparing the efficiency of a 2 blade mower to a 3 blade mower, the former requires less maintenance. The 2 blade mower has fewer moving parts, which means less wear and tear on the machine.

Furthermore, the blades on a 2 blade mower are larger, which means there is less need for sharpening. This translates to less time and money spent on maintenance and more time spent enjoying your lawn.

Disadvantages of 2 Blade Lawn Mowers

First and foremost, these mowers typically have less cutting power than their 3 blade counterparts. This means that they may struggle to handle thicker or taller grass.

Additionally, 2 blade mowers may not be as precise as 3 blade mowers, which can result in a less even cut and the need for additional passes over the same area.

Less Cutting Power

If you’re looking for a quick mow that won’t damage your lawn, a 3 blade lawn mower may be a better choice than a blade model. This is because 3 blade lawn mowers tend to have more cutting power, which allows them to cut through thicker grass more easily.

Additionally, the multiple blades of the 3 blade lawn mower distribute the cutting load more evenly, which can result in improved efficiency and a more even cut. Here are some reasons why a 3 blade lawn mower may be a better choice for you:

  • 3 blade lawn mowers have more cutting power, which allows them to cut through thicker grass more easily.
  •  Multiple blades distribute the cutting load more evenly, which can result in improved efficiency and a more even cut.
  • 3 blade lawn mowers are generally more durable than blade models, which can help you save money in the long run.
  • The multiple blades of a 3 blade lawn mower can create a more professional-looking cut, which can improve the overall appearance of your lawn.
  • 3 blade lawn mowers are often more versatile than blade models, as they can be used for both mowing and mulching.

Less Precision

Less Precision

Opting for a three-bladed lawn mower may result in sacrificing precision for the sake of power. The fewer blades a lawn mower has, the more likely it is to leave uncut grass blades and uneven patches of grass. This is because a single blade or two blades may not be sharp enough to make a clean cut each time.

However, with three blades, the mower can cut through thicker grass and weeds more easily, resulting in a more powerful cut. On the other hand, having more blades does not necessarily mean that you’ll have a cleaner cut. 

If the blades aren’t sharp enough, they won’t cut through the grass cleanly, leaving behind uneven patches.

This is why it’s important to ensure that the blades are always sharp, regardless of the number of blades on your mower. 

Advantages of 3 Blade Lawn Mowers

The 3 blade lawn mowers provide a better-looking, healthier lawn that will make your neighbors envious. Here are four advantages of using a 3 blade lawn mower:

  1. Improved performance: 3 blade mowers have a more efficient cutting system, which means they can handle thicker grass and weeds with ease. This makes mowing your lawn a quicker and smoother process.
  2. Better mulching capabilities: The extra blade in a 3 blade mower helps to create finer grass clippings, which are better for mulching. These clippings break down more easily, which helps to fertilize your lawn and keep it healthy.
  3. Reduced scalping: The 3 blade system provides a more even cut, reducing the chances of scalping your lawn. This is especially important if you have uneven terrain or areas with dips and bumps.
  4. Quieter operation: 3 blade mowers run quieter than their blade counterparts. This can make a big difference if you live in a residential area where noise ordinances are enforced.

Disadvantages of 3 Blade Lawn Mowers

You may want to reconsider using a 3 blade mower because of its blade design. While it’s true that 3 blades can provide a more even cut, it also means that the blades are closer together and may be more prone to clogging. 

This can lead to a decrease in cutting efficiency and require more maintenance to keep the blades clean and sharp.

In addition to its blade design, a 3 blade mower also has higher maintenance requirements compared to a single blade or even a 2 blade mower. With more blades, there are more parts to maintain and replace. This can result in higher costs and more downtime for repairs.

It’s important to consider the long-term costs and maintenance requirements before deciding on a 3 blade mower.

Factors to Consider When Choosing a Lawn Mower

When choosing a lawn mower, there are three factors you should consider: the size of your lawn, the type of grass you have, and your budget.

For a larger lawn, you may want to consider a riding mower or a self-propelled model. Different types of grass require different cutting heights and blade types, so be sure to choose a mower that’s appropriate for your specific lawn.

Finally, your budget will play a role in determining what features and options you can afford.

Size of Lawn

As a homeowner with a small yard, you should consider purchasing a blade lawn mower over a 3-blade one. This is because blade mowers are easier to maneuver, which is essential when mowing a small lawn.

If you have a large property, however, a 3-blade mower may be a better option because it will be able to cover more ground in a shorter amount of time.

It’s also important to consider whether you live in an urban or rural area. If you live in a city, you’re likely to have a small yard, and a blade lawn mower will be your best bet. If you live in a rural area with a larger property, a 3-blade mower may be a better option for the reasons mentioned above.

Type of Grass

The type of grass in your yard plays a crucial role in determining the best blades for your lawn mower. Different grass types have unique characteristics that affect the way they grow and require maintenance. 

As you consider the type of grass in your yard, keep in mind that not all blades are created equal.

Here are some of the best blades and grass type suitability to help you choose the right equipment for your lawn:

  1. For Bermuda grass, consider using a blade with a sharp point that can cut through the tough stems and maintain a clean, even cut.
  2. Zoysia grass requires a blade that can handle its dense growth and maintain a precise cut. Choose a blade with a sharp edge that can slice through the grass without tearing it.
  3. St. Augustine grass requires a blade with a rounded edge that can handle its thick, waxy leaves. Look for a blade with a curved shape that can provide a smooth, even cut.
  4. For fescue grass, consider using a blade with a high lift that can gather clippings and debris from the lawn. Choose a blade with a sharp and durable edge that can maintain a clean cut throughout the mowing process.


Now that you have an understanding of the different types of grass and how they affect your lawn mower choice, let’s move on to the next important factor – budget. 

It’s important to consider how much you’re willing to spend on a lawn mower before making a purchase.

The cost comparison between a blade and a 3 blade lawn mower can be significant, so it’s important to do your research and find a mower that fits both your needs and your budget.

If you’re budgeting for a lawn mower, remember that cheaper isn’t always better. You want to invest in a mower that will last you a long time and perform well. That being said, there are still affordable options that can provide great results.

Some brand recommendations for budget-friendly lawn mowers are Greenworks, Sun Joe, and Yard Machines. These brands offer a range of options at different price points, so you can find a mower that fits both your needs and your budget.

Tips for Maintaining Your Lawn Mower

To keep your lawn mower running smoothly, it’s important to perform regular maintenance tasks like changing the oil and replacing the air filter. Here are some tips for maintaining your lawn mower:

  • Change the oil regularly: This is one of the most important maintenance tasks you can perform. Old oil can cause damage to your lawn mower’s engine and decrease its lifespan. Check your owner’s manual for recommended oil change intervals.
  • Replace the air filter: A dirty air filter can reduce your mower’s performance and make it harder to start. Replace the air filter at least once a year, or more often if you mow in dusty or dirty conditions.
  • Keep the blade sharp: A dull blade can tear your grass instead of cleanly cutting it, which can lead to disease and other problems. Sharpen the blade at least once a year, or more often if you notice it’s not cutting as well as it should.
  • Check the spark plug: The spark plug is responsible for igniting the fuel in your mower’s engine. If it’s dirty or worn out, your mower may not start or run properly. Check the spark plug at least once a year and replace it if necessary.
  • Store your mower properly: If you’re not using your mower for an extended period of time, make sure to store it properly. Drain the fuel tank or use a fuel stabilizer, and store the mower in a dry, protected area.
