10 Best Petrol Lawn Mowers 2025 in the United States

The PowerSmart Lawn Mower is equipped with a 144cc OHV 4-stroke gas engine which is sufficient for small to medium-sized lawns. The 17-inch cutting width is on the smaller side compared to other mowers, meaning it might take longer to mow larger areas. With 6-position dual lever height adjustment ranging from 1.5 to 3.9 inches, it provides flexibility to achieve the desired grass height.

As a push mower, it requires more physical effort compared to self-propelled models, which could be a drawback for some users, especially those with larger yards or uneven terrain. The 3-in-1 feature for rear bagging, side discharge, and mulching is a strength, offering versatile grass clipping management options. The mower is relatively lightweight at 55 pounds and easy to maneuver.

The durable stamped steel deck ensures longevity and reduces vibration, which is beneficial for comfort during use. However, the smaller fuel tank might necessitate more frequent refills. Assembly is simple and tool-free, making it user-friendly from the start. This mower suits homeowners with smaller to medium lawns who prioritize a budget-friendly option and are comfortable with a push model.

The SENIX 20-Inch Gas Lawn Mower is a solid choice for those with small to medium-sized yards who prefer a push mower over a self-propelled model. Equipped with a reliable 125 cc Briggs & Stratton 4-cycle engine, it offers enough power to handle typical lawn conditions without being overly complicated. The 20-inch cutting width is a good middle ground—large enough to mow efficiently but still manageable in tighter spaces.

The mower features a 5-position single wheel height adjustment allowing you to cut grass between 1.25 and 3.75 inches, which covers most common lawn preferences. Its steel deck with a vortex tunnel design helps with even side discharge of grass clippings, although it lacks options like mulching or bagging which some users might miss. Weighing 49 pounds, it is reasonably light, and the 7-inch wheels aid maneuverability, but it is not self-propelled, so it requires more physical effort than models with drive assistance. The fold-down handle is a nice touch for easier storage in smaller garages or sheds.

The mower’s build quality seems durable enough for regular use, backed by a 2-year limited warranty. If you're looking for an affordable, no-frills gas mower that is easy to use and maintain, this SENIX model covers the basics well but may be less suited for larger lawns or those wanting advanced grass clipping management options.
