Dual Blade vs Single Blade Lawn Mowers: Which One Is for You?

In terms of lawnmowers, picking the appropriate one can significantly affect achieving a neat and well-kept lawn. The most popular varieties of lawnmowers include those with dual and single blades.

While single-blade mowers are more straightforward and less expensive, dual-blade mowers are more efficient at tackling thick grass. The choice depends on lawn size, grass type, preference, and budget.

To help you make a decision, this article compares dual blade vs single blade lawn mower based on their advantages, efficacy, and cutting power.

Key Takeaways:

  • Dual-blade mowers excel in efficiency and can tackle denser grass, but may require more upkeep.
  • Single-blade mowers are straightforward and budget-friendly, though they may take more passes for thorough cutting.
  • Choosing between the two depends on factors like lawn size, grass type, and personal preference.
  • Regular maintenance is crucial for both types to ensure optimal performance.

Dual Blade Vs Single Blade Lawn Mower: Which One Is Better?

When comparing dual-blade vs. single-blade lawn mowers, several key features come into play.

Cutting Width

Dual-blade mowers boast a wider cutting width of about 36 inches. This means they can cover nearly five times the area that a single-blade mower can trim in one go, significantly reducing the time and effort required for mowing larger lawns.

In contrast, single-blade mowers typically have a narrower cutting width, around 22 inches, meaning they trim a smaller section of grass with each pass. This can be time-consuming, especially on larger lawns, where it might take an entire day to complete the mowing.

In summary, for efficiency and time-saving, dual-blade mowers are the superior choice, especially for larger lawns. They can cover a substantially larger area in a single pass compared to single-blade mowers.

Cutting Efficiency

Dual-blade mowers are generally faster due to the presence of two blades spinning in opposite directions. This design allows them to cut more grass with each pass, making them highly efficient for larger lawns.

Single-blade mowers, although functional, may need to make additional passes over the lawn to achieve a comparable level of cutting as dual-blade mowers.

Dual-blade mowers are generally superior for speed and efficiency, thanks to their ability to cut more grass per pass, whereas single-blade mowers may require extra passes for comparable results, making them less efficient.


The engine requirements for dual-blade mowers are greater due to their need for more power during operation. Typically, dual-blade mowers are equipped with engines boasting 12-14 horsepower. 

In contrast, smaller single-blade mowers make do with engines that have approximately 6 horsepower. It’s worth noting that higher horsepower not only signifies increased power but also indicates greater durability in a mower.

For those prioritizing power and longevity, dual-blade mowers are the superior option.

Power Consumption

Dual-blade mowers have a tendency to use more power than single-blade mowers, potentially leading to increased long-term energy expenses.

Single-blade mowers are typically more energy-efficient, offering a cost-effective choice for extended use.

Single-blade mowers are the better choice due to their superior energy efficiency and potential for lower long-term energy expenses compared to dual-blade mowers.


In terms of durability, a double-blade mower stands out due to its sturdy construction, reinforced cutting blades, and high-powered engine. This design allows for daily use without risking damage. Moreover, it’s engineered to tackle challenging terrains with thick, stubborn grasses, and its blades remain resilient even in harsh mowing conditions.

Conversely, a single-blade mower tends to be less robust. Its engine may not be as powerful, making it less adept at handling continuous mowing of large, rough grass areas. This can lead to quicker wear and tear compared to its double-blade counterpart.

A single-blade mower may be less robust and more prone to wear and tear, especially in demanding conditions. Double-blade mowers are typically thought to be superior in terms of durability and resilience, making them appropriate for heavy and difficult mowing operations.

Handling Tall Grass

In terms of durability, dual-blade mowers stand out due to their powerful engine and sturdy, thick blades. This combination allows them to efficiently tackle long grass without sustaining damage.

On the other hand, single-blade mowers may face challenges when dealing with tall grass. The strain of cutting through such vegetation could potentially lead to engine issues, potentially causing breakdowns before the task is finished. This emphasizes the advantage of dual-blade mowers in handling more demanding cutting tasks.

Dual-blade mowers demonstrate enabling efficient cutting of long grass without damage, providing an advantage for more demanding tasks compared to single-blade mowers.


Maintaining dual-blade mowers can be a bit more involved due to the presence of two blades. It’s essential to ensure both blades are kept sharp and well-balanced for the best performance.

Maintaining single-blade mowers is typically easier since there is only one blade to take care of.

Single-blade mowers are generally easier to maintain compared to dual-blade mowers, which require attention to two blades for optimal performance.


Dual-blade mowers tend to come with a higher initial cost due to their advanced cutting technology.

Single-blade mowers are generally more affordable in terms of initial costs.

The dual-blade mower comes at a higher cost compared to its single-blade counterpart, attributed to its enhanced functionality and increased durability.
