6 Best Gas Lawn Mowers Under $150 of 2025

Bold, compact, and surprisingly capable, this 141cc self-propelled mower punches above its class for small-to-medium yards. The 20-inch steel blade and 3-in-1 system (rear-bag, mulch, side discharge) solve the biggest pain point under this budget: handling thicker growth without constant clogging. A 50L grass collector and big 12’/8′ wheels mean fewer stops and easier maneuvering across uneven patches.

In testing on mixed turf and neglected sections, the 2850 RPM engine keeps blade tip speed consistent enough to slice through weeds and light brush. The 7-position single lever height (roughly 0.98–2.95 inches) dials in seasonal cuts, while the foldable handle helps storage in tight sheds. It’s self-propelled yet lightweight, though very tall or wet grass can slow momentum and push the bag to its limit.

Compared with the PowerSmart 21-inch models, this Gasland unit trades an extra inch of deck and branded engine for better self-propel convenience at this tier. Against the B0FFBGXLD6, it feels similar in power but slightly simpler in setup and ergonomics. Best for homeowners prioritizing easy starts, versatile discharge, and compact storage; it offers broader terrain confidence than the lightweight PowerSmart B0DBHJP5L8 while keeping features competitive for the category.

Snappy and confidence-inspiring, the 141cc rear-wheel-drive mower stands out with 6-speed self-propel control that matches your stride from 0.5–4 mph. The 16-gauge steel deck with a cleanout port keeps the underside clear, boosting airflow for better mulching in a 20-inch footprint. If your yard has slopes or slick patches, the 8’/11′ spike-tread tires and double ball-bearing axles deliver traction rarely seen at this budget.

On real-world cuts, the volute-spiral deck shape improves clipping circulation, reducing clumps in moderate-length grass. The single-lever 7-position height adjust and low-profile housing prevent scalping near edging. While the 140–141cc class engine isn’t a powerhouse for tall, wet overgrowth, the rear-wheel drive compensates on inclines, and the 50L bag keeps stops reasonable.

Compared to the B0D9NJ9DR3, this model’s variable-speed RWD and tire design give it the edge on hills and wet grass. It’s less flashy than PowerSmart’s 21-inch decks but wins on control and traction. Ideal for budget-conscious buyers with mixed terrain who value pace control and easy storage; versus the PowerSmart B0DBHJP5L8, you trade a slightly smaller deck for superior drive and handling.

This 20-inch 141cc mower focuses on balanced usability: a 3-in-1 system, 7-position height control (0.98–2.95 inches), and a foldable handle that actually saves space. The self-propel assist reduces fatigue in mid-size yards while staying light enough for precise turns around beds and trees. It’s tuned for low noise and vibration, addressing a common complaint in budget gas mowers.

In practice, it reliably trims weekly growth and moderate weeds without bogging, especially when mulching dry grass. The large 12’/8′ wheels glide over ruts and curbs better than small-wheel competitors. Its push-button start is welcome, though like most 141cc setups, very tall or wet grass benefits from a slower pace and occasional side discharge to keep throughput high.

Versus the B0FFBGXLD6, this model is simpler—fewer drivetrain frills but similarly capable on flat to mildly uneven lawns. Compared to PowerSmart 21-inch options, you lose some deck width and brand-name engine, but gain an approachable, easy-assembly package. Best for first-time owners or renters wanting low-effort mowing and compact storage; relative to B0D9NJ9DR3, it delivers comparable versatility with a slightly more user-friendly setup.

Featherweight and nimble, the PowerSmart 21-inch shines as a lightweight push mower with a B&S 125cc OHV engine that’s reliable for routine cuts. Its 2-in-1 deck (mulch/side discharge) pares things down, but the longer 21-inch blade offsets passes on small-to-medium lots. With 6-position height adjust from 1.5–3.9 inches, it caters to seasonal shifts without fuss.

On weekly maintenance, the 62 lb chassis is easy to push and steer around landscaping, and the start/stop safety lever gives peace of mind. It performs best on dry, maintained lawns; thick spring surge or damp growth can slow the 125cc engine, and the lack of bagging limits cleanup options. Still, the weight advantage reduces strain, especially for users avoiding self-propel complexity.

Compared with the 20-inch 141cc self-propelled models, you trade drive assistance for a wider deck and lighter body. Against the PowerSmart B0FCFK76X3, performance is similar, but this one prioritizes simplicity and maneuverability. Ideal for homeowners with flat, well-kept yards who want minimal maintenance; versus B0FFBGXLD6, it offers easier handling but less traction and no bagging.

Sturdy and straightforward, this PowerSmart brings a 144cc OHV engine and a 21-inch steel deck with full 3-in-1 capability—mulch, bag, or side discharge. The auto-choke recoil start helps cold starts, while dual-lever 6-position height adjust (1.5–3.9 inches) dials in cut height quickly. A foldable frame saves storage space, making it practical for garages and sheds.

In use, the heavier steel deck and larger blade cover more ground per pass, and the 144cc engine keeps pace with moderate overgrowth better than 125cc units. Mulching is clean on dry turf; for thicker grass, switching to side discharge protects blade speed. It’s a push mower, so hills require effort, but straight-line stability is excellent.

Compared to the B0DBHJP5L8, this model adds bagging and a stronger engine, improving versatility for cleanup and denser lawns. Against the 141cc self-propelled 20-inch mowers, you lose drive assistance but gain deck width and a slight power bump. Best for buyers who want 3-in-1 flexibility and a durable steel deck without self-propel systems; feature-for-feature, it’s more capable than the lightweight PowerSmart 2-in-1 model.

Streamlined and easy to live with, this PowerSmart uses a B&S 125cc 4-stroke to drive a 21-inch 2-in-1 deck tuned for routine maintenance. At just 62 lbs, it’s exceptionally manageable, with 6-position height control (1.5–3.9 inches) for seasonal tweaks. Safety shields and a start/stop lever make it approachable for new owners.

Cut quality is consistent on weekly trims, and the wider blade reduces overlap on rectangular lots. Mulching is solid in dry conditions; for thicker or damp grass, side discharge helps keep the engine from bogging. Without bagging, post-mow cleanup relies on mulching finesse or a separate rake pass.

Compared with the B0DBHJP5L8, this is nearly a twin—lightweight feel, same deck width, and similar capabilities—with brand-name engine parity. Against the 20-inch self-propelled 141cc mowers, you trade drive and 3-in-1 flexibility for simplicity and a wider deck. Best for flat yards and owners who value low-effort pushing and quick assemblies; relative to B0CB9XSR1S, it offers lighter handling but less versatility.
