Quick Review For Top 9 40v Lawn Mower
Greenworks 40V 16" (Push) Cordless Lawn Mower, 4.0Ah Battery (1/3 Acre, Push Button Start, Compatible with 75+ Tools)
The Greenworks 40V 16 inch Push Cordless Lawn Mower is built for yards up to about a third of an acre. It comes with a 4.0Ah battery that gives you enough runtime for a typical suburban lawn, though the exact time depends on how thick your grass is and how fast you walk.
The 16 inch steel cutting deck is a good size for smaller lawns and tight spaces, so you can get around flower beds and fences without too much trouble.
One of the first things you will notice is how light this mower feels. It is 35 percent lighter than traditional steel deck mowers, which makes a real difference when you are pushing it up a slope or turning it around at the end of a row.
The single lever height adjustment lets you change the cutting height in five different positions, so you can go from a shorter trim in the summer to a taller cut when the weather gets dry.
This mower uses a 2-in-1 system for either mulching or rear bagging. If you want to feed your lawn with natural nutrients, just leave the mulch plug in. When you need to collect clippings, attach the bagger and it catches everything cleanly.
Greenworks 40V 21" Self-Propelled Cordless Lawn Mower – Brushless Motor, 5.0Ah Battery & Charger(75+ Tool Compatible)
The Greenworks 40V 21″ Self-Propelled Cordless Lawn Mower is a solid choice if you are looking to switch from gas without losing power. It comes with a brushless motor that gives you longer runtime and quieter operation—about three times quieter than a gas mower. The 21-inch steel deck is durable and helps deliver a clean, even cut every time.
You get a 5.0Ah battery and a fast charger included, so you are ready to mow right out of the box.
Mowing your lawn does not have to be a workout. This mower is self-propelled with a variable speed control, so you can adjust how fast it moves based on the terrain. The rear-wheel drive gives you good traction, even on slopes or uneven ground.
It is easy to manuver around trees, flower beds, and tight corners without feeling like you are wrestling the machine.
One handy feature is the built-in LED headlight. If you need to mow early in the morning or later in the evening, you can see where you are going without disturbing your neighbors. The light is bright enough to make a real difference when the sun is low or not out yet.
You have four ways to handle the clippings.
Greenworks 48V (24V x 2) 17" Cordless (Push) Lawn Mower (200+ Compatible Tools), (2) 4.0Ah Batteries and Dual Port Rapid Charger Included
The Greenworks 48V (24V x 2) 17″ Cordless Push Lawn Mower is a straightforward tool for getting your grass cut without the fuss of gas or cords. It runs on two 24V batteries that work together to give you 48V of power. With both batteries fully charged, you get up to 45 minutes of run-time. How long it actually lasts depends on your grass and how you mow, but that gives you a solid window for a average sized lawn.
The mower works best when the temperature is between 32°F and 113°F, and you should store it in that same range too.
The deck is 17 inches wide and made from a rust-resistant polymer. It keeps the mower light, so pushing it around flower beds and trees is easy. You won t have to fight a heavy machine to get into tight spots. The single lever lets you pick from five different cutting heights.
Just slide it to where you want, from a close trim to a taller cut, depending on the season or your preference. This mower gives you two options for the clippings. You can mulch them right back into the lawn to feed the grass, or you can use the included rear bag to collect them. The bag catches the clippings, so you can toss them in the compost or yard waste bin.
There is no gas or oil to mess with. No pull cords to yank, no fumes, and no engine noise.

You get a clean, effecient cut every time.
The Intellicut technology automatically adjusts the motor speed based on the grass conditions. If the grass is thick or wet, it kicks up the power. If it’s dry and thin, it saves battery. This helps you get the most out of each charge. You have two options for handling the clippings. You can mulch them right back into the soil, which feeds your lawn naturally. Or you can switch to the rear bag for easy collection. Both methods work well, and switching is simple.
Maneuvering this mower is easy because it only weighs 40 pounds fully assembled. The compact design lets you turn and navigate around flower beds and trees without struggling. The slim deck also features a cut-to-edge design. It gets right up next to fences and garden borders, so you don’t have to go back with a trimmer for those hard-to-reach spots. There are no cords to deal with and no gas or oil to worry about.

No gas, no pull cords, no fuss.
The same batteries work with over 140 tools and outdoor gear from the WORX PowerShare platform. So if you already own other WORX tools, you are already set. If not, you have a whole system to grow into later.
Intellicut is a smart sensor that adjusts the cutting speed based on grass conditions. When the grass is thick, it speeds up to power through. When the grass is light, it slows down to save battery.
This means you get a clean cut without wasting power. The onboard charge-level indicator also shows you the battery status, so you know when it is time to recharge.
You can adjust the cutting height with a single lever. There are six positions ranging from 1.5 inches to 3.5 inches. This lets you set the perfect height for your lawn type. The 14-inch deck is narrow enough to fit through tight spaces and around flower beds.

The Greenworks 60V 21″ Brushless Push Cordless Lawn Mower gives you the kind of power you expect from a gas mower, but without the fumes, noise, or constant maintenance.

This mower is built to handle tough conditions.
The deck is heavy-duty steel with a rust-resistant design, and it carries an IPX4 waterproof rating. That means you can mow in the rain or tackle damp, heavy grass without worrying about damage.

40v Lawn Mower Buying Guide
A 40v lawn mower balances battery power and runtime for medium-sized yards. It’s the sweet spot between lightweight cordless models and heavy-duty 60v or 80v machines. If your lawn is around a quarter-acre or less, this voltage class likely fits your needs without overpaying for power you won’t use. But not all 40v mowers are created equal. Here’s what you should look for.
Deck Size and Material
Deck width determines how many passes you’ll make. Most 40v mowers come with 16 to 21-inch decks. A 21-inch deck covers more ground quickly, but it may feel heavy on slopes. Steel decks last longer than plastic, but they add weight. Plastic decks are lighter and won’t rust. Which matters more to you: durability or ease of pushing?
Battery and Charging Setup
A single 4.0Ah battery usually cuts about 30 to 45 minutes on a full charge. Some 40v mowers include one battery, others come with two. Two batteries mean you can keep mowing while one charges. But check the charger speed — a standard charger takes 2 to 4 hours. If you have a bigger yard, look for a model that accepts larger Ah batteries. You can always buy an extra battery later.
Mulching, Bagging, and Side-Discharge Options
Most 40v mowers offer all three modes. Mulching is great for feeding your lawn, but it works best with a dedicated mulching blade. Bagging catches clippings cleanly, but the bag fills fast on thick grass. Side-discharge is usefull for tall grass, but it leaves clumps. Think about your typical mowing conditions. If you let grass get long often, side-discharge might be your go-to.
Self-Propelled vs. Push
Self-propelled mowers cost more and weigh more, but they save your arms on hilly lawns. Push mowers are simpler and lighter, perfect for flat, small yards. If you’re under 50 and your lawn is level, push is fine. If you dread mowing because it wears you out, invest in self-propelled. Your back will thank you.
Handle and Storage Features
Look for an adjustable handle. Tall or short, you need a comfortable grip. Many 40v mowers fold flat for upright storage. That saves garage space. Also, check if the handle has a soft grip or vibration dampening. Your hands will feel the difference after 20 minutes.
Frequently Asked Questions About 40v Lawn Mower
How does a 40v lawn mower compare to a gas mower?
A 40v lawn mower is quieter and lighter than a gas mower. It starts instantly with a push of a button. You don’t have to deal with gas, oil, or pull cords. It’s better for smaller to medium yards. A gas mower might still be better for very thick grass or large areas.
Will a 40v mower have enough power to cut my lawn?
Yes, for most home lawns. A 40v battery provides good torque for regular grass. It can handle damp grass and some light weeds. If your yard is very large or has really thick, tall grass, you might want a 60v or 80v model. For typical suburban lawns, 40v works great.
How long does the battery last on a 40v mower?
It depends on the battery amp-hour (Ah) rating. A standard 4Ah battery usually runs for 30 to 45 minutes. That’s enough to cut a quarter-acre lawn on one charge. If your yard is bigger, you might need a spare battery or a larger capacity one.
How long does it take to charge the battery?
Charging time varies by charger and battery size. A 4Ah battery typically takes 1 to 2 hours to fully charge. Some fast chargers can do it in 60 minutes. Plan ahead if you have a large lawn. It’s smart to have two batteries so you can keep working.
Are 40v mowers self-propelled?
Some models are, but not all. Self-propelled 40v mowers have a drive system that moves the mower forward. This is helpful on slopes or if you have a large lawn. Check the product specs to see if self-propulsion is included. Manual push models are lighter and cheaper.
Can I use the same battery for other yard tools?
Yes, many brands make 40v batteries that work with trimmers, blowers, and chainsaws. This is a big advantage. You can buy one battery system for all your tools. Stick with the same brand to ensure compatability. This saves you money and hassle.
What is the best way to store the battery in winter?
Store the battery in a cool, dry place. Avoid freezing temperatures. Charge it to about 50% before storing it for months. Don’t leave it on the charger all winter. Check it every few months and recharge if it gets low. This helps the battery last longer.
The Short Answer
Pick a 40v mower that cuts grass cleanly without teh hassle of gas or cords. You want something simple that starts every time with just a push of a button. Look for a mower with a decent battery life so you can finish your yard in one go. A mulching option helps you skip bagging, and adjustable height settings let you handle different grass lengths. Dont overthink it—find a model that feels light enough to push and stores easily in your garage.
Once you pick the right one, you’ll wonder why you didn’t switch sooner. No more trips to the gas station or dealing with tangled extension cords. A reliable 40v lawn mower keeps your lawn looking sharp with less effort, giving you more time to enjoy your weekend.
