How to choose the right one

  1. Select your power source

    Decide between gas and cordless based on your yard size and maintenance preferences. Gas models like the 144cc DB8618C provide consistent power for larger areas without charging delays. Cordless options, such as the 80V PS76821-2026, offer quiet operation and zero emissions. If you prefer simpler upkeep, the 40V MB2417A eliminates oil changes and fuel storage. Choose gas for heavy-duty daily use, or battery for light, infrequent trimming tasks where noise matters.

  2. Match cutting width to yard

    Choose a deck width that matches your space. A 21-inch deck, found on the DV8621C, covers more ground per pass, making it efficient for wide lawns. A 17-inch model, like the MB2417A, fits through narrow gates and around tight obstacles. Smaller decks require more passes but offer better maneuverability in cluttered yards. Measure your gate widths and obstacle spacing before buying to ensure the mower fits your physical layout comfortably.

  3. Check deck material

    Most PowerSmart push mowers feature steel decks for durability. The DB8618C and B8721S2 both use steel to resist impacts and provide a longer lifespan. Steel decks maintain sharpness better than plastic alternatives over time. This material choice supports heavy mulching and side-discharge functions without bending. If you mow over rocky or uneven terrain, the steel construction offers better protection for the blade and internal components during accidental impacts.

  4. Evaluate mowing functions

    Determine how you want to handle grass clippings. The B8721P includes a 1.4-bushel bag for clean yard appearance, ideal for homeowners who dislike debris. The DV8621C offers 2-in-1 mulch and discharge for flexible disposal. The MB2417A provides 3-in-1 options, including bagging, mulching, and side discharge. Choose side discharge only if you do not mind clippings remaining on the lawn. Mulching returns nutrients to the soil, while bagging keeps the yard tidy.

  5. Consider battery capacity

    For cordless models, battery capacity determines runtime. The MB2417A includes a 4.0 Ah battery, suitable for small lawns up to one-eighth acre. Higher voltage options, like the 80V PS76821-2026, deliver more power for thicker grass. If you have a larger yard, check if the battery covers the entire area in one charge. Lower capacity batteries may require mid-mow recharging, interrupting your workflow. Match the Ah rating to your square footage for uninterrupted mowing.
