If you've been mowing the same way for years, the idea of switching to a cordless electric lawn mower might feel unfamiliar. The Greenworks 40V 16in push lawn mower represents a real shift in how people maintain smaller properties. Before deciding whether this type of equipment makes sense for you, it helps to understand what cordless mowing actually means, what battery-powered tools can and can't do, and how to figure out whether your garden is the right size for this approach.

Understanding Battery-Powered Mowing and What 40V Means

The "40V" in the Greenworks 40V 16in push lawn mower refers to the voltage of the battery system. In practical terms, this tells you the power level of the tool. Higher voltage generally means more cutting power and longer runtime, but 40V sits in the middle range of cordless mower options and is suitable for residential yards rather than commercial or very large properties.

The battery that comes with this model is a 4.0Ah unit—the "Ah" stands for amp-hours, which measures how much electrical charge the battery holds. A larger amp-hour rating means the battery lasts longer before needing to recharge. The 4.0Ah battery can cut up to one-third of an acre on a full charge, though actual runtime varies based on grass thickness, wetness, and how aggressively you mow. Dense, overgrown grass demands more power than a well-maintained lawn, so you'll get different results depending on your yard's condition.

Is a 16-inch Cutting Width Right for Your Lawn

The "16in" refers to the width of the mower deck—essentially how much grass gets cut with each pass. A narrower deck means you'll need more passes to cover the same area, which takes longer. A wider deck covers ground faster but becomes harder to maneuver in tight spaces.

For most residential properties up to one-third acre, a 16-inch cutting width offers a reasonable balance. It's narrow enough to navigate around garden beds, patios, and parked cars, but wide enough that you won't spend all weekend mowing. If your lawn is mostly open with few obstacles, you might prefer a wider deck. If your property has lots of trees, fences, or tight corners, a narrower deck becomes valuable.

Battery Life, Runtime, and Charging Expectations

One significant difference between cordless and gas mowers is refueling. Instead of stopping to add petrol, you recharge the battery. The Greenworks 40V system comes with both the battery and a charger, so you're ready to start immediately.

Plan for one mow per charge during the growing season. Most people charge overnight or between mowing sessions. Battery performance declines in cold weather—if you live somewhere with short springs or early winters, charging times may lengthen and runtime may shrink in cooler months. Store the battery indoors during winter for best longevity.

One advantage of the Greenworks 40V platform is compatibility: this battery works with more than 75 other Greenworks cordless tools, including trimmers, blowers, and chainsaws. If you already own other Greenworks equipment, a second battery becomes a practical investment rather than dead money.

Mulching, Bagging, and Grass Handling

The Greenworks 40V 16in push lawn mower offers a 2-in-1 system, meaning you can either mulch clippings back into the lawn or bag them. Mulching returns nutrients to soil and eliminates trips to the compost heap, but it works best on dry grass and mowers over clippings finely. Bagging gives you more control and is essential if your lawn is wet, overgrown, or you're dealing with lots of fallen leaves.

Weight, Height Adjustment, and Maintenance

At 35% lighter than traditional steel-deck mowers, the Greenworks 40V model is notably easier to push and maneuver, particularly for people with less upper body strength. The single-lever height adjustment with five positions lets you set cutting height without wrestling with multiple bolts—simply move one lever to raise or lower the deck.

Cordless electric mowers need far less maintenance than petrol models. There's no spark plug to replace, no oil to change, and no seasonal winterizing. Rinse the deck occasionally to prevent grass buildup, keep the battery contacts clean, and you're done. The Greenworks 40V 16in push lawn mower comes with a three-year limited warranty covering both the tool and battery, which reflects the manufacturer's confidence in durability for home use.
