10 Best Gas Lawn Mowers 2025 in the United States

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 SENIX LSPG-M4 is a solid choice for those with small to medium-sized yards who prefer a reliable push mower. It comes with a 125 cc Briggs & Stratton 4-cycle engine, which is known for being quiet, eco-friendly, and easy to start thanks to its Prime 'n Pull' system. Its 21-inch cutting width offers a good balance between covering ground quickly and maneuverability around tight spaces. The mower includes a 6-position dual-lever height adjustment, ranging from 1.25 to 3.75 inches, so you can customize the grass length to your preference without much hassle.

Though it's a push mower rather than self-propelled, the durable 11-inch rear and 8-inch front wheels make it easier to maneuver than some other push models. The 2-in-1 steel deck supports mulching and side discharge but lacks a bagging option, which might be a downside if you want to collect grass clippings easily. The mower folds down for compact storage and comes with engine oil included, plus a 2-year warranty for peace of mind. Weighing 57 pounds, it’s a bit heavy but manageable for most users.

If you’re looking for a straightforward, durable gas mower without the extra complexity of self-propulsion or bagging, the SENIX LSPG-M4 delivers good value and ease of use.

The PowerSmart 21-inch Gas Push Lawn Mower is a solid choice if you have a small to medium-sized lawn and want a reliable, easy-to-use mower. It features a 140cc Briggs and Stratton engine with a ReadyStart system, which means starting it should be hassle-free without pulling too hard or struggling. The 21-inch cutting width is a good middle ground—wide enough to cover ground efficiently but still manageable for maneuvering around obstacles.

This mower offers six cutting height options between 1.5 and 3.9 inches, allowing you to customize your lawn's length easily with a single lever. While it is a push mower, it does have a decent 1.4-bushel rear bag for collecting clippings, which helps keep your yard tidy and makes disposal easier. The sturdy steel deck and heavy-duty blade are designed for clean, fine cuts even on thicker grass, helping maintain a healthier lawn.

Since it’s not self-propelled, mowing larger or uneven areas may require more physical effort compared to models with propulsion. The engine and design suggest it’s suitable for routine residential use rather than very large properties. If you're looking for a mower that balances ease of start, good cutting performance, and practical features like mulching and bagging in a straightforward push design, this mower fits well. Heavier users or those with extensive lawns might find a self-propelled option easier to handle.
