The 21-inch cutting width means you can cover a decent amount of ground in less time, which is a significant plus for larger yards.

Weighing in at 61.6 pounds, it’s manageable but could feel heavy for some users. Additionally, while the recoil starter is generally easy to use, it may pose a challenge for those unfamiliar with starting gas engines. If you're a homeowner looking for a straightforward, budget-friendly mower that handles a variety of tasks, the PowerSmart Gas Lawn Mower could be a great fit.

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.
