10 Best Gas Lawn Mowers 2025 in the United States

The PowerSmart Gas Lawn Mower is a solid choice for those seeking a reliable push mower for their lawns. With a 144cc OHV engine, it provides ample power for tackling various grass types. The 21-inch cutting width means you can cover a decent amount of ground in less time, which is a significant plus for larger yards. One of the standout features is the 3-in-1 capability, allowing for mulching, bagging, and side discharge, giving you flexibility based on your mowing needs. This versatility makes it great for homeowners who want options for handling grass clippings.

The dual-lever cutting height adjustment with six positions provides the convenience of customizing your cut from 1.5 to 3.9 inches, allowing for precision based on the season or grass type. The mower's foldable design is also a bonus, saving storage space when not in use.

On the downside, being a push mower, it requires more physical effort compared to self-propelled models, which could be a consideration for those with larger, hilly lawns or less strength. Weighing in at 61.6 pounds, it’s manageable but could feel heavy for some users. Additionally, while the recoil starter is generally easy to use, it may pose a challenge for those unfamiliar with starting gas engines. If you're a homeowner looking for a straightforward, budget-friendly mower that handles a variety of tasks, the PowerSmart Gas Lawn Mower could be a great fit.

The SENIX LSPG-M7 is a solid choice for small to medium yards. It features a powerful 140 cc Briggs & Stratton engine known for its reliability and low vibration, making maintenance easier. The 21-inch cutting width helps you cover more ground in less time, and the 6-position dual-lever height adjustment allows for precise cutting, ranging from 1.25 to 3.75 inches.

Its 3-in-1 functionality (mulching, side discharge, and bagging) provides versatile options depending on your lawn care preferences. The mower includes an ergonomic handle to enhance user comfort, and its sizable 16-gallon bagger reduces the frequency of emptying clippings. The 8-inch front and 11-inch rear wheels offer decent maneuverability, even on uneven terrain.

One notable downside is that it is a push mower, not self-propelled, which might be tiring for larger or particularly hilly yards. Additionally, at 54 pounds, it might be a bit heavy for some users to push. The Prime N' Pull starting mechanism is designed for ease of use, though some users may find it less convenient than electric start models. The mower also includes accessories like engine oil, mulch plug, side discharge chute, and bagger, and comes with a 2-year limited warranty for peace of mind. If you are looking for a straightforward, reliable gas mower for regular yard maintenance, the SENIX LSPG-M7 is worth considering.

The Greenworks 80V 21" Brushless Cordless Lawn Mower offers a convenient and eco-friendly alternative to traditional gas-powered mowers. It provides up to 60 minutes of run-time with a fully charged 4.0Ah battery, though this can vary based on grass conditions and how the mower is used. The brushless motor is a highlight, delivering more torque, quieter operation, and longer lifespan compared to standard motors. Its 21-inch cutting deck is durable and efficient, allowing for quicker mowing sessions.

Additionally, the 3-in-1 system supports mulching, rear bagging, and side discharge, adding versatility. The mower features a single lever with 7 cutting height positions, making it adaptable to different grass conditions. The push button start eliminates the need for gas, oil, and emissions, making it user-friendly and environmentally conscious. However, it is a push mower, which might be less convenient for larger or hilly lawns compared to self-propelled models.

The included 80V 4.0Ah battery and rapid charger are practical, but users should consider the limited run-time for extensive lawns. Weighing 74.1 pounds, it may be heavier than some other cordless options, potentially making it harder to maneuver for some users. Given its features, this mower is best suited for small to mid-sized lawns and users looking for a low-maintenance, quiet, and eco-friendly mowing experience.
