10 Best Gas Lawn Mowers 2025 in the United States

The PowerSmart gas lawn mower comes with a 144cc 4-cycle OHV engine, which offers a good balance of power for average yard mowing tasks without being too heavy or complicated. Its 18-inch cutting width is a solid size for small to medium lawns, allowing you to cover ground at a reasonable pace. The mower features a 6-position dual lever height adjustment, ranging from 1.5 to 3.9 inches, which gives you decent flexibility to choose the grass height you prefer. Being a push mower, it doesn't have self-propelled assistance, so it requires manual effort, which might be tiring on larger or uneven lawns. However, the 7-inch durable wheels and ergonomic handle help make maneuvering somewhat easier, especially in tighter spaces.

The 3-in-1 functionality (bagging, mulching, and side discharge) is a strong point, allowing you to manage grass clippings according to your preference or lawn conditions. The included rear bag is easy to empty, which adds convenience. Starting the mower is straightforward thanks to the recoil starter with an auto choke, making it beginner-friendly for users who might be wary of gas mowers. Assembly is simple with no tools required, which is a plus if you want to get started quickly.

This mower is manual push only, so it may not be ideal if you have a large lawn or need a mower with more power or self-propulsion for easier handling. Also, being made in China, some might want to consider durability and parts availability though customer reviews averaging 4.1 stars suggest reasonable satisfaction. This mower fits well for homeowners with small to medium-sized lawns who want a reliable, easy-to-start push mower with versatile cutting options without the need for advanced features or self-propulsion.

The SENIX 20-Inch Gas Lawn Mower features a robust 125 cc 4-cycle Briggs & Stratton engine, which is reliable and efficient for small to medium-sized yards. The 20-inch cutting width ensures a generous cutting area, and the steel deck provides durability. The mower's 5-position single wheel height adjustment allows for flexibility in cutting height, ranging from 1.25 to 3.75 inches, which is suitable for various lawn conditions.

The side discharge is effective for dispersing grass clippings evenly, but it lacks mulching and bagging options which might be a drawback for some users seeking more versatility in grass management. Weighing 49 pounds, it is relatively lightweight and easy to maneuver, aided by its 7-inch wheels that perform well in tight spaces. The manual Prime n Pull starting mechanism is straightforward, but some users might prefer an electric start for added convenience.

The fold-down handle is a plus for easy storage, saving space when not in use. The mower comes with engine oil and is backed by a 2-year limited warranty, adding value and peace of mind for buyers. As a push mower, it requires physical effort to operate, which may be less appealing to those who prefer self-propelled options. Potential buyers should weigh the convenience of its features against the absence of mulching and bagging options and the manual start mechanism.

The BILT HARD 21 Inch Lawn Mower is designed for those seeking a reliable and efficient gas-powered option for lawn care. With a powerful 201cc engine, it delivers strong performance and torque, making it suitable for tackling various lawn conditions. The 21-inch cutting width is advantageous for covering larger areas swiftly, while the 3-in-1 functionality—mulching, bagging, and side discharge—adds versatility, allowing users to choose their preferred method of grass disposal based on their needs.

One of the standout features is the adjustable cutting height, which offers a range from 1.2 inches to 3.75 inches. This flexibility is great for tailoring the mower to different grasses or seasons. The mower is also designed for comfort during operation, with double ball-bearing wheels that enhance maneuverability and a foam-wrapped grip to reduce hand fatigue, making the mowing experience more pleasant.

However, there are a few drawbacks to consider. As a push mower, it requires physical effort, which may not be ideal for everyone, especially those with larger properties or physical limitations. The weight of 57.8 pounds can make it a bit cumbersome for some users. Additionally, while the no-choke, no-primer starting mechanism is user-friendly, some might still find gas-powered mowers less convenient compared to electric models, particularly in terms of maintenance and fuel management.
