How to Choose the Best Walk-Behind Lawn Mowers
Power Source and Performance
The choice between gas, corded electric, and cordless electric significantly impacts a mower's performance and maintenance. Gas mowers, like the YARDMAX 22 in. 201cc, typically offer robust power and extended runtime without being tethered, making them suitable for larger, tougher lawns. However, they require fuel, oil changes, and produce emissions and noise. Cordless electric models, such as the Greenworks 40V series or the MZK 20V, provide a quieter, emission-free experience with less maintenance. Their runtime is limited by battery capacity, usually ranging from 30 to 75 minutes depending on the battery (e.g., 4.0Ah vs. 5.0Ah) and grass conditions. Brushless motors, found in many Greenworks and MZK models, are reported to deliver more power, longer life, and greater efficiency than brushed alternatives.
Deck Size and Propulsion
Deck size dictates how much ground a mower covers with each pass, directly affecting mowing time. Smaller decks, like the MZK 13-inch or Greenworks 16-inch, are ideal for compact yards or areas with tight turns, prioritizing maneuverability. For larger properties, a 21-inch or 22-inch deck, as seen in the Greenworks 40V 21" or YARDMAX 22 in. models, can significantly reduce the time spent mowing. Propulsion type is another critical factor. Push mowers, such as the Greenworks 40V 16" Cordless, require the user to manually propel them, which is suitable for smaller, flatter yards. Self-propelled mowers, like the YARDMAX 22 in. or Greenworks 40V 21" Self-Propelled, feature a drive system that propels the mower forward, greatly reducing user fatigue, especially on larger or sloped lawns.
Ergonomics and Additional Features
Comfort and convenience features can drastically improve the mowing experience. Ergonomic handles and ultra-lightweight designs, like the Greenworks 40V 16" model, make maneuvering easier. Height adjustment systems vary, with single-lever controls (e.g., Greenworks 40V 16" offers 5 positions) generally being more convenient than individual wheel adjustments (e.g., MZK 20V 13" offers 4 positions). Look for 2-in-1 or 3-in-1 capabilities (bagging, mulching, side discharge) to manage grass clippings effectively. Some advanced cordless models, like the Greenworks 40V 21" Self-Propelled, even include LED headlights for extended mowing hours. The YARDMAX 22 in. gas mower features an automatic choke system, which simplifies starting and eliminates the need for manual priming.
Pros & Cons

- Cordless 40V system provides gas-like performance for smaller yards without emissions.
- Single-lever 5-position height control offers easy adjustment for various grass types.
Cons

- Automatic choke system simplifies starting, eliminating manual priming.
Cons
- Requires fuel and oil, leading to more maintenance compared to electric models.
- Gas mowers typically produce more noise and emissions.

Pros
- Brushless motor delivers powerful, quiet operation with extended runtime.
- Self-propelled rear-wheel drive with variable speed control reduces user effort.
- Integrated LED headlights allow for flexible mowing times, even in low light.

Common Mistakes to Avoid
Underestimating Battery Capacity for Yard Size
A common pitfall for new cordless mower users is selecting a battery capacity that doesn't match their lawn's needs. For instance, a Greenworks 40V 16" mower with a 4.0Ah battery might be sufficient for a small, flat yard, but users with larger or denser lawns might find the 45-minute runtime insufficient, requiring multiple charges. In practice, a larger 5.0Ah battery or higher voltage system, like the Greenworks 48V (24V x 2) setup, typically provides the necessary endurance for more substantial properties.
Ignoring the Importance of Propulsion Type
Many first-time buyers overlook the benefit of self-propelled functionality, particularly for yards with slopes or significant square footage. Opting for a push mower, such as the MZK 20V 13" Electric Lawn Mower, on a large or uneven terrain can lead to considerable fatigue. Self-propelled models, like the YARDMAX 22 in. with FWD or the Greenworks 40V 21" Self-Propelled, significantly reduce physical exertion, making the mowing experience much more manageable.
Disregarding Cutting Height Adjustment Range
Not all height adjustment systems offer the same versatility. Some mowers, like the MZK 20V 13", provide a range from 1.3 inches to 2.6 inches, which might be too restrictive for certain grass types or seasonal preferences. Conversely, the Greenworks 40V 16" offers a broader range from 1.25 inches to 3.375 inches, allowing for more precise control over lawn aesthetics and health. Selecting a mower with an appropriate and easy-to-use height adjustment system is crucial for optimal lawn care.
