10 Best Gas Lawn Mowers 2025 in the United States

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.

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 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.
