The Greenworks 40V 16″ Cordless Lawn Mower is designed for homeowners who want a clean, quiet, and simple way to maintain their lawn. If you have a yard up to about a half acre, this mower offers a practical alternative to gas-powered machines, eliminating the familiar hassles of fuel, fumes, and loud noise. Its core strength is effortless power.
You get gas-like performance from a 40V lithium-ion battery, which provides up to 35 minutes of continuous runtime on a full charge—enough to cover that half-acre yard. Recharging is straightforward and takes about two hours. The mower starts with a simple push-button, so there’s no pulling a cord and hoping the engine turns over. You just press and go, which is a nice change of pace. A major highlight is the ultra-lightweight design.
It’s about 35% lighter than many standard cordless mowers, making it much easier to push and maneuver around yard obstacles, flower beds, and tight corners. The 16-inch steel cutting deck is a managable size for most lawns, and the ergonomic handles contribute to overall comfort during use. When you’re done, its compact build makes for easy storage in a shed or garage. Managing your cut is simple with the smart cut adjustment.
Greenworks 40V 21" Self-Propelled Cordless Lawn Mower – Brushless Motor, 5.0Ah Battery & Charger(75+ Tool Compatible)

It moves away from the noise, fuss, and maintenance of gas mowers, offering a cleaner, quieter alternative that doesn’t compromise on performance. At its heart is a brushless motor, which is key to its efficiency.
This motor provides strong, consistent torque for a clean cut, runs significantly longer on a single charge, and operates at about three times quieter than a traditional gas model. You can have a conversation or listen to music without the roar of an engine, which is a nice change. One of the biggest upgrades here is the self-propelled feature. The rear-wheel drive system provides excellent traction, and you can ajust the speed to match your walking pace.
Whether you’re on flat ground or a slight incline, the mower does the hard work of pushing itself, so you’re just guiding it. This makes mowing large or hilly yards much less of a chore. Adding to the convenience are the bright LED headlights. If your schedule only allows for early morning or evening mowing, you can see clearly and finish the job without waiting for daylight, all while keeping noise to a minimum for your neighbors.

Lithium Ion Lawn Mower Buying Guide
Lawn mowers with lithium-ion batteries offer quick charging, long life, and consistent power. But with so many models out there, how do you pick teh right one for your yard? This guide will help you cut through the noise and find a mower that makes your weekly chore simple and efficient.
Battery Voltage and Runtime
Think of voltage as the mower’s muscle. A 40V model is great for a small, flat lawn. For a larger yard or thicker grass, you’ll want 56V or even 80V for extra torque. Runtime is just as crucial. Check the amp-hour (Ah) rating alongside the voltage. A 40V, 5.0Ah battery will last longer than a 40V, 2.5Ah one. You need enough power to finish your lawn on a single charge.
Cutting Deck Size and Adjustability
A wider deck means fewer passes to mow your lawn. A 20-inch deck is standard, but 21-inch models are common too. For bigger properties, look for 22 inches or more. Don’t forget height adjustment! A simple, single-lever system that changes the height for all wheels at once is a huge time-saver compared to adjusting each wheel individually.
Drive System and Maneuverability
Do you have hills or a large yard? A self-propelled mower is worth it. It does the pushing for you, making the job much easier. Consider the drive type: rear-wheel drive offers better traction on slopes, while front-wheel drive provides tighter turning. For a small, flat lawn, a push model is lighter and less expensive.
Storage and Maintenance Features
How will you store it? A mower that folds for vertical storage can save a ton of garage space. Also, look at how easy it is to clean. A deck wash port lets you hose out clippings without tipping the mower over. These little features add up to a much more convenient experience season after season.
Frequently Asked Questions About Lithium Ion Lawn Mower
How long does the battery last on a single charge?
It depends on your lawn size and the mower’s power. Most models run for 45 to 60 minutes. That’s usually enough for a typical suburban yard. Check the product specs for your model’s exact runtime.
Are lithium ion mowers powerful enough?
Yes, modern ones are very powerful. They easily handle thick grass and light weeds. For very tough, overgrown yards, you might want to check the motor’s voltage. Higher voltage generally means more cutting power.
How long do the batteries last before needing replacement?
The battery itself should last for several years. You can expect around 500 charge cycles on average. That means if you mow weekly, it could last up to a decade before it’s capacity fades significantly.
Is it much lighter than a gas mower?
Usually, yes. There’s no heavy engine or gas tank. This makes them easier to push and maneuver, especially on slopes. The weight is more balanced to, which helps with fatigue.
What’s the main advantage over a gas mower?
They’re much simpler to use. You just press a button to start. There’s no oil, gas, or spark plugs to deal with. They’re also quiet and produce no fumes, so you can mow early without bothering neighbors.
Can I leave the battery on the charger all the time?
It’s best not to. Most modern chargers stop when full, but for battery health, unplug it once charged. Store the battery in a cool, dry place, not in extreme heat or cold.
What about safety?
They are very safe. There’s no risk of fuel fires. The mower won’t start unless you’re holding the safety handle. Always remove the battery before cleaning or clearing a jam, just to be sure.
Are they more expensive?
The upfront cost can be higher than a basic gas mower. But you save money over time on gas and maintenance. You also don’t have the hassle of winterizing the engine or changing the oil.
The Final Call
When selecting a modern cordless mower, battery life and consistent power delivery are the ultimate deciding factors for value. It’s not just about the price tag. It’s about how many passes you can make on a single charge and whether the motor keeps up in thick grass. A mower that fades halfway through the job isn’t a tool, it’s a frustration. Focus on the battery’s voltage and amp-hour rating, and look for real-user reviews about runtime in conditions similar to your own lawn.
This focus on core performance leads you straight to the best choice for most homeowners: a modern lithium ion lawn mower. These models offer the perfect balance of quiet operation, zero-maintenance convenience, and, most importantly, the steady power you need from the first cut to the last. By prioritizing the battery system, you invest in a tool that simplifies your routine for seasons to come, giving you a great-looking lawn without the hassle.
