Who it fits
Good fit for
This mower suits homeowners with medium to large lawns who prefer a self-propelled drive. The 25-inch width covers ground quickly. The dual battery system ensures you finish the job without stopping to recharge. It is ideal for those already invested in the Greenworks 40V ecosystem, as it works with over 75 compatible tools. The steel deck offers durability for regular residential use.
Who should skip it
You should look elsewhere if you need a lightweight, push-only mower. This unit weighs 76.2 pounds and includes self-propulsion, which adds weight. If your lawn is small, the 25-inch deck may be too wide and cumbersome. Also, skip this if you need extremely long runtime beyond 70 minutes, as the batteries will deplete on very large or thick grass areas without swapping charges.
Verdict: It is a robust, wide-cutting option for those who want to save time on larger lawns. The dual battery system and self-propelled drive make it a practical choice for sustained mowing sessions.
Key specs explained
Runtime: 70 min
This rating indicates the mower can run for up to 70 minutes on two fully charged 4.0Ah batteries. Actual time varies based on grass thickness and your walking speed. This duration suits medium-sized lawns where you can complete the task in one go. Larger properties may require recharging or additional batteries to finish the job without interruption.
Cutting Width: 25 in
A 25-inch deck covers a wide path with each pass. This width reduces the number of passes needed to mow a lawn compared to narrower models. It helps you finish larger areas more quickly. Ensure your gate openings and side passages are wide enough to accommodate this width comfortably during operation.
Motor Type: brushless
Brushless motors do not use carbon brushes, which reduces friction and wear. This design typically offers more torque and longer life than brushed alternatives. It also operates more quietly and efficiently. You benefit from consistent power output and reduced maintenance needs over the lifespan of the tool.
Drive Type: self-propelled
The self-propelled system moves the mower forward automatically. It adjusts to your walking speed, reducing physical effort. This feature is useful for slopes or thick grass. You guide the machine rather than pushing it, making mowing less tiring and allowing for a more consistent cutting pace across the yard.
Battery Capacity: 4.0Ah
The 4.0Ah capacity determines how much energy the battery holds. Two of these batteries are included for extended runtime. Higher amp-hour ratings generally mean longer operation before recharging. This capacity supports the 70-minute runtime claim and is compatible with other 40V Greenworks tools in your collection.
Design and Build Analysis
The listing specifies a 25-inch steel deck. Steel provides durability for larger lawns, allowing you to handle extensive grass areas quickly. The mower measures 27.6 inches wide, 45.3 inches high, and 53.6 inches long. It weighs 76.2 pounds. This weight contributes to stability during self-propelled mowing, helping the machine maintain consistent speed as you walk. The dual battery ports are positioned for automatic switchover. This layout ensures uninterrupted runtime when one 4.0Ah battery depletes, switching seamlessly to the second unit.
According to the listing, the motor is brushless. This design choice offers more torque and quieter operation compared to brushed alternatives. It also suggests a longer component life. The single lever height adjustment provides seven positions. This control layout allows you to select the optimal cut height for various environments without complex tools. The 3-in-1 function lets you mulch, side discharge, or rear bag clippings. This versatility means you can adapt the mower to your waste disposal preference. The finish combines green and black colors. The overall design prioritizes functional efficiency and robust construction for regular lawn maintenance tasks.
Setup and Everyday Use Guide
You begin by inserting the two 4.0Ah batteries into the dual ports. The system supports automatic switchover, so you do not need to manually swap cells when one depletes. This feature ensures uninterrupted run-times up to 70 minutes, provided the grass conditions are manageable. You adjust the single lever to select from seven cutting heights. This allows you to tailor the cut for different environments, from short lawns to taller, overgrown areas. The 25-inch steel deck is designed for durability. You can choose between mulching, side discharge, or rear bagging depending on your preference and grass volume. The self-propelled drive adjusts to your walking speed, reducing physical effort. You simply guide the mower rather than pushing it. The brushless motor provides quiet operation and consistent torque. This makes daily mowing less disruptive to neighbors. The unit weighs 76.2 pounds, which contributes to stability but requires careful maneuvering in tight spaces. You can connect this mower to other Greenworks 40V tools, expanding your toolkit. The 3-year limited warranty covers the tool and batteries. You benefit from dependable long-term ownership. Setup is straightforward, focusing on battery installation and height adjustment. Daily use involves selecting your preferred discharge method and letting the self-propel system handle the forward motion. You control the direction and speed. This setup suits users who want efficiency without complex electronic controls.
Before You Buy This Mower
You should verify that your existing Greenworks 40V tools use the same battery platform. This mower is part of a system with over 75 compatible devices. If you already own trimmers or blowers from this brand, these 4.0Ah batteries will work across your toolkit. This compatibility reduces the need to purchase separate power sources. You must also consider storage space. The unit measures 53.6 inches long and weighs 76.2 pounds. Ensure your garage or shed can accommodate this size. Regular upkeep involves cleaning the steel deck after use to prevent grass buildup. This maintains cutting efficiency and protects the metal surface. When comparing this option to other cordless lawn mowers, note that the self-propelled drive reduces physical effort. The brushless motor offers quiet operation and longer life. This makes it suitable for users who prioritize ease of use and system integration over raw power alone.
Check before you buy
- Confirm you own other Greenworks 40V tools for shared battery use.
- Measure your storage space to fit the 53.6-inch length.
- Check that your lawn size matches the 70-minute runtime limit.
- Ensure you have access to a standard electrical outlet for charging.

Frequently asked questions
Does this mower require assembly before first use?
You will need to assemble the handle and wheels before operating the unit. The specifications list the assembled dimensions as 53.6 inches long, 27.6 inches wide, and 45.3 inches high. You attach the handle to the steel deck and secure the wheels to the axle. This setup allows you to reach the specified 25-inch cutting width immediately after installation.
How does the dual battery system improve runtime?
The mower features two ports for 40V batteries, allowing automatic switchover when one cell depletes. You insert two 4.0Ah batteries to achieve up to 70 minutes of total runtime. This design prevents interruption during mowing sessions. You do not need to manually swap batteries mid-cut, which helps maintain consistent performance across medium-sized lawns without stopping to recharge.
Is the 25-inch cutting width suitable for small yards?
The 25-inch steel deck covers a wide path, making it efficient for medium lawns. It may be cumbersome for very tight spaces due to its 53.6-inch length and 76.2-pound weight. You should measure your yard access points. The self-propelled drive aids maneuverability, but the physical size requires adequate turning radius and storage space in your garage or shed.
What type of motor does this Greenworks model use?
This unit uses a brushless motor, which offers improved efficiency and longer lifespan compared to brushed alternatives. The 40V power source drives this motor to cut grass up to 25 inches wide. Brushless technology reduces maintenance needs since there are no carbon brushes to replace. You benefit from consistent power delivery throughout the battery charge cycle.
Can I use my existing Greenworks 40V batteries?
Yes, this mower is compatible with the Greenworks 40V battery platform. You can use your existing 4.0Ah batteries if you own other tools in this ecosystem. The system includes over 75 compatible devices. Using shared batteries ensures you have spares available. This compatibility allows you to rotate charged cells between your mower and other yard tools as needed.
How heavy is the mower when fully assembled?
The mower weighs 76.2 pounds when fully assembled with batteries installed. This weight provides stability on slopes but requires effort to lift for storage. The self-propelled drive system offsets much of this mass during operation. You do not need to push the mower manually, which makes the weight manageable for most users on flat or gently sloping terrain.
What is the maximum height of cut for this model?
The specifications do not list specific height settings, but the steel deck allows for standard adjustment. You typically adjust the cut height using a single lever that sets all wheels simultaneously. This feature ensures an even cut across your lawn. You should check the control lever for multiple positions to accommodate different grass types and seasonal growth rates.
