The SENIX LSSG-H2 is a solid choice for small to medium yards thanks to its 22-inch cutting width, which helps you mow quickly without missing spots. Its 163 cc Briggs & Stratton 4-cycle engine provides dependable power for most typical lawn jobs, and the front-wheel drive self-propel system makes pushing easier, especially on slightly uneven terrain. You can adjust cutting height in six steps, ranging from 1.25 to 4 inches, so it’s flexible enough to handle different grass lengths. The mower’s 3-in-1 capability lets you mulch, bag, or side-discharge clippings, which is great for managing lawn waste your way. Included accessories like the 19-gallon bagger and washout port make cleanup and maintenance more convenient.

The mower is also designed with comfort in mind, offering an ergonomic handle and large rear wheels for better maneuverability. The front-wheel single-speed drive is simpler than variable speed options, which can limit control on very hilly or rough terrain. At 66 pounds, it’s relatively lightweight for a gas mower but might be a bit heavy for some users to lift or transport easily. The fold-down handle and vertical storage are nice space-savers for smaller garages.

Backed by a 2-year warranty and supported by generally positive user reviews, this mower serves as a practical, reliable option for homeowners seeking a straightforward, versatile gas mower without extra frills.

Cutting Height Adjustment
The convenience of a single handle to adjust the cutting height is incredibly user-friendly.
Starting Mechanism
The push button start eliminates the hassle of pull cords and gas, adding to the overall ease of use.

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.

Starting Mechanism
The mower starts easily and runs powerfully, handling high grass without strain and delivering an even cut.

The SENIX 144 cc Gas Lawn Mower is a solid choice for homeowners with medium to large yards who need a reliable push mower. Its 144cc 4-cycle engine provides good power, making it capable of handling varied grass types and slopes efficiently. The 21-inch cutting width covers a decent area in one pass, which can save you time compared to smaller mowers. With six adjustable cutting heights from 1.25 to 3.75 inches, it offers flexibility to maintain different grass lengths based on your preference or season.

The mower’s high wheel design (8-inch front, 11-inch rear) improves maneuverability over uneven or rugged terrain, which is a plus if your yard isn't perfectly flat. It also features 2-in-1 functionality, allowing you to mulch or side discharge clippings, helping keep your lawn healthy or clear depending on your needs. However, this mower is a push model without self-propulsion, so it requires more effort to move, especially on bigger or hilly lawns. The starting mechanism is manual, meaning you’ll need to pull the cord to start the engine, which might be challenging for some users.

At about 48 pounds, it’s neither too heavy nor too light, but still manageable for most users. Installation is straightforward with the included instructions, and the 2-year warranty adds peace of mind. For those seeking a dependable mower with solid power and basic features without the complexity of self-propulsion, the SENIX 144 cc is a fitting option, especially if you don’t mind the extra physical effort.

Buying Guide for the Best Gas Lawn Mowers

Choosing the right gas lawn mower can make a significant difference in maintaining your lawn efficiently and effectively. When selecting a gas lawn mower, it's important to consider various specifications that will impact its performance, ease of use, and suitability for your specific lawn care needs. Understanding these key specs will help you make an informed decision and ensure you get the best fit for your lawn.
Engine PowerEngine power, measured in horsepower (HP) or cubic centimeters (cc), determines the mower's ability to cut through thick or tall grass. Higher engine power means more cutting strength and efficiency. For small to medium-sized lawns with regular grass, an engine with lower power (around 140-160cc) is sufficient. For larger lawns or tougher grass, consider a mower with higher power (above 160cc). Choose based on the size of your lawn and the type of grass you have.
Cutting WidthCutting width refers to the width of the mower's cutting deck and determines how much grass is cut in a single pass. A wider cutting width (20-22 inches) covers more ground quickly, making it ideal for larger lawns. A narrower cutting width (16-18 inches) is more maneuverable and better suited for smaller lawns or areas with tight spaces. Select a cutting width that matches the size and layout of your lawn for efficient mowing.
Cutting Height AdjustmentCutting height adjustment allows you to change the height at which the mower cuts the grass. This feature is important for maintaining the health of your lawn, as different grass types and seasons require different cutting heights. Mowers typically offer multiple height settings, ranging from 1 to 4 inches. Choose a mower with easy-to-use height adjustment options that suit your grass type and seasonal needs.
Self-Propelled vs. PushSelf-propelled mowers have a drive system that moves the mower forward, reducing the effort required to push it. This is especially useful for larger lawns or hilly terrain. Push mowers, on the other hand, rely on your strength to move them and are better suited for smaller, flat lawns. Consider your lawn size, terrain, and physical ability when deciding between self-propelled and push mowers.
Mulching, Bagging, and Side DischargeThese are the three main grass clipping disposal options. Mulching mowers finely chop the grass and return it to the lawn as natural fertilizer. Bagging mowers collect clippings in a bag for disposal, leaving a clean lawn. Side discharge mowers expel clippings out the side, which can be left on the lawn or raked up later. Choose a mower with the disposal option that best fits your lawn care routine and preferences.
Fuel Tank CapacityFuel tank capacity determines how long the mower can run before needing a refill. Larger tanks allow for longer mowing sessions without interruption, which is beneficial for larger lawns. Smaller tanks are lighter and may be sufficient for smaller lawns. Consider the size of your lawn and how often you want to refuel when choosing the fuel tank capacity.
Starting MechanismThe starting mechanism can be either a recoil (pull) start or an electric start. Recoil start mowers require pulling a cord to start the engine, which can be physically demanding. Electric start mowers use a battery-powered starter, making them easier to start with the push of a button. Choose a starting mechanism based on your preference for convenience and ease of use.
