10 Best Gas Lawn Mowers 2025 in the United States

The SENIX 144 cc Gas Lawn Mower is a solid choice for homeowners with medium to large yards who need a reliable push mower. Its 144cc 4-cycle engine provides good power, making it capable of handling varied grass types and slopes efficiently. The 21-inch cutting width covers a decent area in one pass, which can save you time compared to smaller mowers. With six adjustable cutting heights from 1.25 to 3.75 inches, it offers flexibility to maintain different grass lengths based on your preference or season.

The mower’s high wheel design (8-inch front, 11-inch rear) improves maneuverability over uneven or rugged terrain, which is a plus if your yard isn't perfectly flat. It also features 2-in-1 functionality, allowing you to mulch or side discharge clippings, helping keep your lawn healthy or clear depending on your needs. However, this mower is a push model without self-propulsion, so it requires more effort to move, especially on bigger or hilly lawns. The starting mechanism is manual, meaning you’ll need to pull the cord to start the engine, which might be challenging for some users.

At about 48 pounds, it’s neither too heavy nor too light, but still manageable for most users. Installation is straightforward with the included instructions, and the 2-year warranty adds peace of mind. For those seeking a dependable mower with solid power and basic features without the complexity of self-propulsion, the SENIX 144 cc is a fitting option, especially if you don’t mind the extra physical effort.

The SENIX LSSG-H2 is a solid choice for small to medium yards thanks to its 22-inch cutting width, which helps you mow quickly without missing spots. Its 163 cc Briggs & Stratton 4-cycle engine provides dependable power for most typical lawn jobs, and the front-wheel drive self-propel system makes pushing easier, especially on slightly uneven terrain. You can adjust cutting height in six steps, ranging from 1.25 to 4 inches, so it’s flexible enough to handle different grass lengths. The mower’s 3-in-1 capability lets you mulch, bag, or side-discharge clippings, which is great for managing lawn waste your way. Included accessories like the 19-gallon bagger and washout port make cleanup and maintenance more convenient.

The mower is also designed with comfort in mind, offering an ergonomic handle and large rear wheels for better maneuverability. The front-wheel single-speed drive is simpler than variable speed options, which can limit control on very hilly or rough terrain. At 66 pounds, it’s relatively lightweight for a gas mower but might be a bit heavy for some users to lift or transport easily. The fold-down handle and vertical storage are nice space-savers for smaller garages.

Backed by a 2-year warranty and supported by generally positive user reviews, this mower serves as a practical, reliable option for homeowners seeking a straightforward, versatile gas mower without extra frills.

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.
