How to Choose the Right Gas Mower

  1. Match Engine Power to Yard Size

    Check the engine displacement in cubic centimeters, or cc, to ensure adequate power for your grass type. Larger engines handle thick or wet grass better. For small, flat yards, a 140cc or 144cc engine is sufficient. Models like the PowerSmart 18-Inch 144cc Gas Push Mower offer enough torque for light duty. If you have larger areas or tougher turf, consider a 170cc engine. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower uses a 170cc OHV engine for more robust performance. Higher cc ratings generally mean better cutting consistency under load. Choose based on your typical grass density.

  2. Select Drive Type for Terrain

    Decide between push and self-propelled drives based on your yard slope. Push mowers require physical effort but are lighter and simpler. The PowerSmart 21-Inch 144cc Gas Push Mower is ideal for flat lawns where you do not need assistance. Self-propelled models reduce fatigue on inclines. The PowerSmart 22-Inch Self-Propelled Gas Mower features rear-wheel drive for better traction on slopes. Rear-wheel drive helps the mower pull itself forward. If your yard has hills, a self-propelled unit saves energy. For perfectly flat surfaces, a push mower is often sufficient and easier to store.

  3. Choose Cutting Width for Efficiency

    The deck width determines how much grass you cut in one pass. Wider decks cover more ground but are heavier and harder to maneuver. An 18-inch deck, found on the PowerSmart 18-Inch 144cc Gas Push Mower, is nimble for tight spaces. A 21-inch or 22-inch deck, like the PowerSmart 21-Inch 170cc Self-Propelled Gas Mower, is better for open areas. Wider cuts mean fewer passes. However, wider mowers weigh more. The PowerSmart 22-Inch Gas Self-Propelled Lawn Mower weighs 75 pounds. Balance coverage speed with your ability to handle the weight and width.

  4. Pick Mowing Function for Clippings

    Decide how you want to handle grass clippings. Mulching returns nutrients to the soil. Bagging collects clippings for disposal. Side discharge throws clippings to the side. The PowerSmart 21-Inch 140cc Gas Push Mower is best for mulching on flat lawns. The PowerSmart 21-Inch 140cc Gas Push Mower offers bagging for clean yards. The PowerSmart 21-Inch 3-in-1 Gas Push Lawn Mower provides mulching, bagging, and side-discharge options. Choose a model that matches your preferred disposal method. Some models only offer side discharge. Ensure the chosen function fits your lawn care routine.

  5. Check Deck Material for Durability

    Look at the deck material to gauge longevity. Steel decks are common and durable. They resist impacts from debris better than plastic. Most PowerSmart models, including the PowerSmart 18-Inch 144cc Gas Push Mower, feature steel decks. Steel is heavy but long-lasting. It requires occasional cleaning to prevent rust. The PowerSmart 21-Inch 140cc Gas Push Mower also uses a steel deck. A rigid steel deck maintains blade alignment better over time. If you mow over rocky terrain, a steel deck offers better protection. Consider the weight trade-off for the added durability and cutting performance.
