This greenworks 40v 21 inch push lawn mower review focuses on a cordless option designed for straightforward yard maintenance. It features a 21-inch steel deck that provides a wide cutting path for efficient grass removal. The unit is powered by a 40V brushless motor, which delivers consistent torque while operating quietly. A key specification is the included 5.0 Ah battery, which supports up to 60 minutes of run time depending on conditions. This push mower does not use self-propulsion, requiring you to move the unit manually. It offers three discharge modes to suit different lawn preferences.
- Brushless motor for longer life and quiet operation
- 21-inch steel deck for durable cutting performance
- Up to 60 minutes of run time with 5.0 Ah battery
- Dual battery port allows one battery to charge while the other is in use
- Vertical storage feature saves up to 70% of garage space
Good fit for
This mower suits homeowners with small to medium lawns who prefer quiet operation and zero emissions. The push design works well for flat, even terrain where manual effort is manageable. If you already own other Greenworks 40V tools, the shared battery platform adds value. The mulching, bagging, and side discharge options provide flexibility for different grass conditions. You will appreciate the vertical storage if garage space is limited.
Who can skip it
You should look elsewhere if you have a large property exceeding the 60-minute battery life. The lack of self-propulsion may be tiring on slopes or uneven ground. If you need extended runtime for bigger yards, consider models with dual batteries or gas engines. The push mechanism requires physical effort, which might not suit everyone. Those wanting automated features or advanced connectivity should explore other brands.
Verdict
This mower is a solid choice for small to medium lawns where quiet operation and ease of storage matter. It delivers reliable performance for users who do not need self-propulsion or extended runtime.
Key specs explained
Voltage: 40V
This rating indicates the electrical power available to the motor. A 40V system typically offers enough strength to handle standard residential lawns without the weight of a gas engine. You get consistent power for cutting medium-thick grass. Compare this with 20V models if you have smaller yards, or gas engines for heavy-duty commercial work. Higher voltage generally means better performance under load.
Cutting Width: 21"
The deck covers a 21-inch swath with each pass. This width balances speed and maneuverability for average suburban yards. You will cover more ground per minute than with a 17-inch deck, reducing overall mowing time. However, it may feel bulky in tight spaces between garden beds. Check your yard’s layout to ensure you have enough room to turn the mower easily.
Run Time: Up to 60 minutes
The battery provides up to one hour of operation on a full charge. This duration suits most medium-sized lawns in a single session. Actual time varies based on grass height, thickness, and your walking speed. If your yard exceeds this capacity, consider buying a second battery. This spec helps you plan your workflow without needing to refuel or pause for gas.
Motor Type: Brushless
This motor lacks physical brushes, reducing friction and wear over time. You benefit from quieter operation and longer motor life compared to brushed alternatives. It also delivers more torque for cutting dense grass efficiently. This design means less maintenance for you, as there are no brushes to replace. It is a practical choice for users wanting a low-maintenance, durable power source.
Battery Capacity: 5.0 Ah
The amp-hour rating defines the energy storage size. A 5.0 Ah battery holds more charge than a 2.5 Ah unit, extending your run time significantly. This capacity supports the full hour of operation mentioned in the specs. It also allows you to swap batteries between compatible tools in the same system. Ensure you have enough outlets to charge it, as it takes longer to fill than smaller batteries.
Design and Build Details
According to the listing, this mower features a 21-inch steel deck. Steel construction provides durability and resistance to impact compared to plastic alternatives. The deck supports a 21-inch cutting width, which covers more ground per pass. This layout suits homeowners with medium-sized lawns who want to reduce mowing time.
The unit weighs 62 pounds and measures 65.4 inches in length, 21.7 inches in width, and 33.1 inches in height. These dimensions define the physical footprint you need for storage and maneuvering. The push drive type means you provide the forward motion. This design keeps the mechanism simple but requires physical effort to guide the machine across the yard.
Greenworks includes a dual battery port design. This feature allows you to store one battery while the other powers the mower. It saves a trip to the garage when you need to swap power sources. The unit also supports vertical storage, which helps you save space in your garage or shed. The finish is described as green, matching the brand’s typical aesthetic. These build choices prioritize practical storage and straightforward operation for residential use.
Setup And Daily Use Overview
Setting up this mower begins with charging the included 5.0 Ah battery. The listing notes a dual battery port design, which allows you to store one battery while the other powers the unit. This feature helps reduce trips to the garage during setup or when swapping charges. Assembly typically involves attaching the handle and rear bag or mulch plug, depending on your chosen function.
Daily use is straightforward due to its push drive type. You do not need to manage a self-propelled mechanism, which keeps the weight manageable at 62 pounds. The 21-inch steel deck cuts a wide path, allowing you to cover lawns efficiently. The brushless motor provides quiet operation and consistent torque, making it suitable for standard residential tasks. You can choose between mulching, rear bagging, or side discharging clippings. This 3-in-1 design offers flexibility for different yard conditions and disposal preferences.
Runtime is listed as up to 60 minutes with the fully charged battery. Keep in mind that actual run time varies based on grass thickness and your mowing speed. The mower works with over 75 other Greenworks 40V tools, so you can share batteries across your toolkit if you own other cordless equipment. For storage, the unit supports vertical positioning, which saves space in your garage.
