9 Best Self-Propelled Gas Lawn Mowers 2025 in the United States

The BILT HARD 21 Inch Self-Propelled Gas Lawn Mower offers a solid package for homeowners needing a reliable mower for medium to larger lawns. Its 201cc 4-cycle OHV engine provides good power and torque, which helps handle different grass thicknesses without much strain. The 21-inch cutting width is a practical size—not too wide or narrow—allowing you to mow efficiently without being too bulky. The mower has rear-wheel drive with a single-speed self-propelled system, which makes pushing easier, especially on uneven ground or slopes, although it doesn’t offer adjustable speed control to customize pace. Adjusting the cutting height is simple with one lever controlling all four wheels, letting you pick from eight height positions between 1.2 and 3.75 inches to suit various lawn conditions. The steel deck is durable and supports three cutting options: mulching, bagging, and side discharge, providing flexibility depending on how you want to manage grass clippings.

Starting the mower is hassle-free thanks to the no-choke, no-primer design, making it user-friendly for those not interested in fiddling with manual start steps. The foam-padded handle adds comfort during use, which can reduce fatigue over longer mowing sessions. The mower weighs 79 pounds, so it’s on the heavier side, which might be less convenient when transporting or storing. Also, the single-speed propulsion means you can't adjust your walking speed while mowing. This mower suits users looking for a dependable, straightforward self-propelled gas mower with versatile cutting options and easy starting, especially if you have medium-sized lawns and want a balance of power and convenience without extra complexities.

The PowerSmart Self Propelled Gas Lawn Mower with a 140cc Briggs and Stratton engine offers solid performance for homeowners needing reliable lawn care.

The rear-wheel drive system helps maintain good traction on slopes and uneven ground, which is a plus if your lawn isn’t perfectly flat. You’ll appreciate the 6-position cutting height adjustment, although it uses a 2-wheel height control which might feel a bit less precise compared to 4-wheel options.

The mower supports 3 cutting modes—mulching, side discharge, and bagging—with a reasonably sized 1.4-bushel grass bag that’s easy to empty. Starting the mower is straightforward thanks to the Prime ’N Pull system, reducing the struggle often associated with gas mowers. Weighing about 59 pounds, it’s manageable for most users, but not the lightest model out there. The manual speed control typical of self-propelled mowers might require some getting used to for smooth operation. The deck's alloy steel construction boosts durability.

This mower receives a customer rating of 4 out of 5 stars, reflecting good user satisfaction for its price point. It fits well for those with moderately sized lawns who want a dependable machine with multiple cutting options and easy starting, especially if you need help on slopes.
