Choosing the best 40V lawn mowers requires looking at the hard numbers. We compared 15 models based strictly on the specifications published on their listings. The Greenworks 40V 14-Inch Cordless Push Mower leads because its 33.3-pound weight and 14-inch cutting width make it ideal for small lawns and tight spaces.
This guide helps you decide which mower fits your yard size and storage needs. You will find options for push or self-propelled drives, different battery capacities, and varied deck widths. Read on to see how each spec impacts your mowing routine.
Match Cutting Width to Yard Size
Your yard size determines the ideal cutting width. Small lawns under a quarter acre fit 14-inch or 15-inch decks, like the Greenworks 14-Inch model. Medium yards benefit from 20-inch or 21-inch options, such as the WORX 21-Inch. Wider decks cover more ground per pass but require more storage space and physical effort to push.

Is 40V Power Worth It for Your Lawn?
The 40V rating indicates the electrical system’s potential output, influencing motor performance and runtime. In this comparison, every model uses 40V, so the voltage itself does not distinguish them. Instead, you should look at battery capacity, measured in Amp-hours (Ah), to gauge endurance. Higher Ah ratings, such as the 6.0Ah found in the SKIL model or the 5.0Ah options from WORX and Greenworks, typically support longer mowing sessions. The voltage ensures compatibility within specific brand ecosystems, like the WORX PowerShare system, allowing you to swap batteries across tools.
Worth it if
- You already own other 40V tools from the same brand.
- You need extended runtime for medium to large lawns.
Skip it if
- You prefer gas-powered engines for maximum torque.
- You only have a small yard under a quarter acre.

You can review our spec-based picks for the best 40V lawn mowers to evaluate battery runtimes and cutting widths.
How We Selected These 40V Mowers
We gathered these 15 models by scanning Amazon listings for the 40V voltage specification. We only included products where this voltage appeared in the title or feature list. This ensures every item on the list actually uses a 40V battery system. We kept only one size variant per product family to avoid redundancy.
The list orders products in stock first. Then it ranks by overall rating weighted by count, followed by how many guide criteria the specs meet. We verified details like cutting width and drive type directly from the published data. We did not handle these units or test them personally. All information comes strictly from the manufacturer listings.
How to choose the right one
Check the drive type
Drive type determines how the mower moves. Push models require you to exert physical effort, while self-propelled versions move forward on their own. If you have uneven ground or a steep slope, self-propelled models like the PowerSmart 20-Inch or the Husqvarna LE-322R reduce fatigue. Push mowers, such as the Greenworks 14-Inch, are lighter and easier to store. Choose self-propelled for large or hilly yards, and push for small, flat areas where maneuverability is key.
Look at battery capacity
Battery capacity, measured in Amp-hours (Ah), dictates runtime. Higher numbers mean longer operation before recharging. The WORX 21-Inch includes a 5.0 Ah battery, offering more power than the 4.0 Ah units in the Greenworks 14-Inch. Some models, like the Greenworks 25-Inch, support dual batteries for extended sessions. If you have a large yard, prioritize higher Ah ratings or dual-battery compatibility. Smaller yards can manage with standard 4.0 Ah batteries without frequent interruptions.
Select the motor type
Motor type affects efficiency and maintenance. Brushless motors are generally more efficient, durable, and require less upkeep than brushed alternatives. The WORX 21-Inch and the PowerSmart 20-Inch both feature brushless motors, ensuring consistent power delivery. This technology extends the lifespan of the tool. If you plan to use the mower frequently, a brushless motor is a practical choice. It reduces wear and tear, keeping your 40V system running smoothly over time without complex maintenance.
Review mowing functions
Mowing functions define how clippings are handled. Some models offer 3-in-1 capabilities, including mulching, bagging, and side discharge. The WORX 21-Inch supports all three, giving you flexibility for different lawn conditions. Other tools, like the ZEGJAW 15-Inch, focus on vacuuming for artificial turf. If you want to recycle clippings or collect them neatly, look for multi-function decks. Specialized tools may lack these options but excel in specific tasks like debris removal on synthetic grass.
Consider the weight
Weight impacts portability and storage. Lighter mowers are easier to lift into cars or store in tight spaces. The Greenworks 14-Inch weighs only 33.3 pounds, making it highly maneuverable. Heavier models, like the Husqvarna LE-322R at 102 pounds, offer stability but require more effort to move. If you have stairs or narrow doorways, prioritize lower weight. For flat, open lawns, a heavier unit may provide better traction and durability during extended use.
Match deck width to space
Deck width determines coverage per pass. Narrow decks, like the 14-inch Greenworks, are ideal for tight spaces and small yards. Wider decks, such as the 25-inch Greenworks, cover more ground quickly. The WORX 21-Inch offers a middle ground for medium yards. Choose a width that matches your lawn size to avoid excessive passes. Wider decks are efficient for large areas but may struggle in confined spaces with many obstacles or narrow gateways.
Frequently asked questions
Which 40V mower is best for small lawns?
The Greenworks 40V 14-Inch Cordless Push Mower is the top choice for small spaces. It features a 14-inch cutting width and weighs only 33.3 pounds. This compact design makes it easy to maneuver around tight obstacles and store in small sheds.
Do I need a self-propelled 40V mower?
You need a self-propelled model if you have uneven terrain or a steep slope. The PowerSmart 20-Inch and Husqvarna LE-322R models provide this drive type. They move forward on their own, reducing the physical effort required to push the mower across difficult ground.
Which 40V mower has the widest cutting deck?
The Greenworks 40V 25-Inch Self-Propelled Mower offers the widest 25-inch cutting deck on this list. A wider deck covers more ground per pass, which is ideal for large lawns. It uses a dual-battery system to maintain power across these broader cuts.
Are there 40V mowers with brushless motors?
Yes, several models include brushless motors for improved efficiency and durability. The WORX 21-Inch, PowerSmart 20-Inch, and Husqvarna LE-322R all feature this technology. Brushless motors generally offer longer runtimes and require less maintenance than brushed alternatives, enhancing overall performance.
What is the lightest 40V mower on the list?
The WORX 40V 14-Inch Cordless Dethatcher and Scarifier is the lightest option at 26.2 pounds. It is designed for aeration and debris removal rather than standard grass cutting. Its low weight makes it easy to handle for maintenance tasks on small yards.
Can I use a 40V mower for artificial turf?
The ZEGJAW 40V 15-Inch Artificial Turf Sweeper is built specifically for synthetic lawns. It includes a vacuum function to remove debris and comb fibers. This tool is not suitable for natural grass but excels at keeping artificial turf clean and looking its best.
Which 40V mower is best for large lawns?
The Husqvarna LE-322R 22-Inch Self-Propelled Mower suits large yards with its heavy build and dual batteries. It provides extended runtime and a 22-inch cutting width. This combination allows you to tackle bigger areas efficiently without frequent battery swaps or recharging.
Do any 40V mowers come with a leaf blower?
The BILT HARD 40V 17-Inch Combo and SENIX 40V 15-Inch Combo both include a leaf blower. These kits provide two tools in one package, which is practical for light-duty maintenance. They allow you to mow and clear debris using the same battery system.
