Who it fits
Good fit for
This mower suits homeowners with small to medium lawns under a quarter acre. The 20-inch deck and push design work well for tight spaces. You will appreciate the brushless motor for its efficiency. The 48V system provides enough power for typical grass conditions. If you already own Greenworks 24V tools, the batteries are compatible. The steel deck handles daily use reliably.
Who should skip it
Skip this model if you need self-propelled ease. The push design requires physical effort. You should look elsewhere if your lawn exceeds half an acre. The 20-inch deck is narrow for large areas. Runtime may be short for thick or wet grass. The weight is 67.2 pounds, which is manageable but not light. If you want a wider cut, this 20-inch width is limiting.
Verdict: This mower delivers solid 48V power in a compact push format. It is a practical choice for small, manageable lawns.
Key specs for this mower
Voltage: 48V (24V x 2)
This mower combines two 24V batteries to create 48V of power. You get more torque and cutting strength than single 24V models. This helps cut thicker grass without bogging down. If you have a moderately thick lawn, this extra power keeps the blade spinning steadily. It fits users who already own 24V Greenworks tools, allowing you to share batteries across your toolkit.
Runtime: up to 45 min
You can mow for up to 45 minutes on a full charge. This time applies when using two fully charged 4Ah batteries. Runtime drops if the grass is tall or wet. For small to medium lawns, this duration is usually enough to finish the job. Larger properties may require a spare battery or a longer charge cycle to complete the task without interruption.
Cutting Width: 20 in
The deck cuts a 20-inch path in a single pass. This width balances speed and maneuverability. It is wide enough to reduce mowing time on open areas. It is narrow enough to navigate around garden beds and trees. If you have a large, open yard, a wider deck saves time. For tight spaces, this size offers a practical middle ground.
Motor Type: brushless
The brushless motor lacks carbon brushes, which reduces friction and wear. You get longer motor life and quieter operation. It also provides more efficient power delivery, which can extend your runtime. This type of motor is common in higher-end cordless mowers. It means less maintenance for you over the years and consistent performance as the tool ages.
Deck Material: steel
The cutting deck is made of durable steel. This material resists dents and impacts from rocks or debris better than plastic. It provides a solid base for the blade, which can improve cut quality. Steel decks are heavier, which may affect how easily you push the mower. This choice suits buyers who prioritize longevity and durability over minimal weight.
Design and build specs
The listing describes a durable steel 20-inch cutting deck. Steel resists dents and impacts better than plastic on rough terrain. This material choice supports the 20-inch cutting width, allowing you to cover more ground per pass. The brushless motor drives the deck. This design reduces friction and heat, which helps maintain consistent power and extends the tool's life. You get quiet operation alongside this efficiency. The mower is a push model. You control the speed and direction manually. This layout offers precise maneuverability around obstacles but requires physical effort. It suits flat to gently sloping yards where you want direct control over the cut quality.
According to the listing, the overall dimensions are 20.9 inches in width, 40.2 inches in height, and 61.8 inches in length. The unit weighs 67.2 pounds. This weight comes from the steel deck, the brushless motor, and the included two 4.0Ah batteries. The heft provides stability during mowing, reducing vibration. However, you must lift it for storage or transport. The green finish is standard for the brand. It is practical and easy to spot in a shed. The handle height is adjustable up to 40.2 inches, accommodating different user heights. This ergonomic feature ensures comfortable operation for most adults. The compact width fits through standard gate openings. You can store it in tighter spaces than wider commercial models. The design prioritizes durability and manageable size for residential use.
Setup and daily operation details
Setup begins with combining two 24V batteries to create the 48V power system. This configuration delivers higher torque than single battery models, which helps maintain consistent cutting speed in thick grass. The included dual-port charger allows you to charge both 4.0Ah batteries simultaneously, reducing downtime between sessions. You do not need to manage complex wiring or fuel lines. The push drive type means you provide the forward motion. This requires physical effort but offers precise control over the cutting path. The 20-inch steel deck provides a stable base. Steel resists damage from hidden debris better than plastic, ensuring the blade remains aligned for a clean cut. The brushless motor operates quietly, making early morning or late evening mowing less disruptive to neighbors. Runtime extends up to 45 minutes with two fully charged batteries. This duration varies based on grass height and your mowing speed. The mower fits into the broader 24V platform, meaning you can use existing Greenworks batteries for other tools like trimmers or blowers. This compatibility simplifies your overall cordless toolkit. The unit weighs 67.2 pounds. This weight adds stability during operation but requires care when lifting it into a garage or shed. Height adjustments allow you to set the cutting level to suit your lawn’s needs. The three-year limited warranty covers both the tool and the batteries, providing long-term reliability. You can expand your equipment range without buying new chargers or separate power sources.
Before You Buy This Mower
You already have the mower and two 4.0Ah batteries in the kit. The listing notes compatibility with over 200 Greenworks 24V tools. This means you can share batteries with trimmers, blowers, or chainsaws. Check if you own other Greenworks 24V gear. If you do, this system integrates well. If not, consider if you want to build a new toolkit. The dual-port charger is included, which helps manage battery life. You will need to keep the steel deck clean after use. Grass clippings stick to metal and can cause rust if ignored. Wipe it down regularly. Compare this push model to self-propelled options if your lawn has slopes. The 20-inch width suits small to medium yards. Larger properties might need wider decks or longer runtime. Ensure your storage space fits the 67.2-pound unit with batteries installed. This mower fits into the mid-range of cordless choices, balancing power and portability.
Check before you buy
- Check if you own other Greenworks 24V tools for battery sharing
- Verify your storage space fits the 67.2-pound mower with batteries
- Confirm lawn size suits the 20-inch cutting width
- Ensure you have a dry place to store the steel deck

Frequently asked questions
Does this mower have self-propulsion?
No, it is a push model. The specifications list the drive type as Push. You must manually propel the 67.2-pound unit across your lawn. This design keeps the weight manageable but requires more physical effort than self-propelled alternatives.
How wide is the cutting deck?
The cutting width is 20 inches. This measurement allows you to cover a moderate amount of ground per pass. The overall width of the mower is 20.9 inches, which accounts for the deck and side panels.
What is the total runtime on a single charge?
The listing indicates up to 45 minutes of runtime. This duration depends on grass thickness and cutting height. You use two 4.0 Ah batteries to achieve this power level. Thicker grass will reduce the total cutting time.
Can I use my existing Greenworks batteries?
Yes, it works with the 24V platform. The product data notes compatibility with over 200 Greenworks 24V tools. You can share your existing batteries with trimmers, blowers, or chainsaws. This reduces the need to buy separate power sources for other garden tasks.
What material is the cutting deck made of?
The deck is made of steel. This material offers better resistance to dents and impacts compared to plastic. It supports the 20-inch cutting width and provides durability on rough terrain. Steel construction helps maintain the structural integrity of the mower over time.
How heavy is the Greenworks mower?

Is this mower suitable for large lawns?
