To protect your mower from weather exposure, evaluate dimensions across the best storage sheds for lawn mowers.
Key Specs to Compare
-
Check drive type
You must decide between push and self-propelled models based on your lawn's slope and size. Push mowers require physical effort to move. The Greenworks 40V 16-Inch Push Lawn Mower is a lightweight option for small, flat areas. Self-propelled models like the 21-inch version reduce strain on hilly terrain. Choose push for ease of storage and lower weight. Select self-propelled if you want to cover ground without manual pushing.
-
Match cutting width
Cutting width determines how many passes you need to finish your yard. Narrow decks like the 15-inch Dethatcher are for specialized tasks, not mowing. Standard mowers range from 16 to 25 inches. A 16-inch or 17-inch deck suits small lawns under a third of an acre. Larger properties benefit from the 25-inch self-propelled model. Wider decks cut more grass per pass, reducing total mowing time significantly.
-
Review battery capacity
Battery capacity in Amp-hours (Ah) dictates runtime. Higher Ah values provide longer operation before recharging. Most models include a 4.0 Ah battery. The 21-inch self-propelled mower features a larger 5.0 Ah battery for extended use. Check if the kit includes the battery or if it is tool-only. Buying a tool-only model saves space if you already own compatible Greenworks 40V batteries from other tools.
-
Consider motor type
Brushless motors offer greater efficiency and durability compared to brushed alternatives. They generate less heat and require less maintenance over time. The 17-inch brushless push mower and the 25-inch self-propelled model both use this technology. Brushless motors often provide consistent power as the battery drains. If you plan to use the mower frequently, a brushless motor is a practical choice for long-term reliability.
-
Verify weight and size
Weight affects maneuverability and storage. Lighter models like the 33.5-pound 16-inch mower are easier to lift and store. Heavier self-propelled units, such as the 76.2-pound 25-inch model, offer stability but require more effort to move manually. Check the overall dimensions for garage or shed fit. Ensure the handle folds down properly if you have limited storage space. Compact designs are ideal for small urban yards.
