Who it fits
Good fit for
This mower suits homeowners with medium-sized lawns who want a reliable cordless solution. The 21-inch cutting width covers ground efficiently. The brushless motor is ideal for those who value quiet operation and durability. If you already own Greenworks 40V tools, this integrates seamlessly. The vertical storage feature helps those with limited garage space. It is also good for users who prefer manual push mowers over self-propelled models.
Who should skip it
You should look elsewhere if you need self-propelled power for hilly terrain. This model is a push mower, requiring more physical effort on slopes. Large properties may exceed the 60-minute runtime on a single charge. If you need extended runtime, consider models with dual batteries or higher capacity. Users seeking a bagging-only setup might find the 3-in-1 design less specialized. The steel deck is heavy, so lift capability matters for transport.
Verdict: This mower is a solid, durable choice for medium lawns that value cordless convenience and integration with the Greenworks 40V system. It offers practical features but requires manual pushing and careful battery management.
Key specs explained for this mower
Cutting Width: 21 in
A 21-inch deck covers a moderate swath of grass with each pass. This width balances speed and maneuverability for average suburban lawns. It is wider than 20-inch models, reducing the number of passes needed. You will finish mowing faster on flat terrain. It fits well in standard gate openings without being too wide.
Runtime: Up to 60 min
The 5.0 Ah battery provides up to 60 minutes of operation on a single charge. This duration suits medium-sized yards where you can complete the job in one go. Runtime varies based on grass thickness and your mowing speed. If your lawn is larger, you may need a spare battery or a higher capacity option to avoid stopping mid-cut.
Motor Type: Brushless
A brushless motor eliminates carbon brushes, reducing friction and wear. This design offers higher torque for cutting dense grass and operates more quietly than brushed alternatives. It also extends the overall life of the tool. You benefit from longer intervals between maintenance and consistent power delivery throughout the battery charge cycle.
Deck Material: Steel
The steel deck provides durable resistance against impacts from rocks and debris. It maintains its shape better than plastic decks over time. This material is ideal for yards with uneven ground or hidden obstacles. It adds weight to the mower, which can help with stability but may make lifting slightly heavier.
Mowing Function: 3-in-1 mulch/rear bag/side discharge
This configuration allows you to mulch clippings back into the lawn, bag them for cleanup, or discharge them to the side. Mulching nourishes the soil, while bagging keeps the yard tidy. Side discharge is useful for clearing longer grass quickly. You can switch modes to match your lawn care goals and local regulations.
Design and build overview
The listing describes a 21-inch push mower with a steel deck. Steel construction typically offers greater durability than plastic, which matters if you encounter rocks or uneven terrain. The deck width balances speed and maneuverability for average suburban lawns. You get a cutting swath that reduces the number of passes needed for medium-sized yards.
The overall dimensions are 65.4 inches long, 21.7 inches wide, and 33.1 inches high. The unit weighs 62 pounds. This weight provides stability during mowing but requires physical effort to push. Since it is a push model, there is no self-propulsion system to assist you on slopes or thick grass. You must provide the forward momentum yourself.
The mower features a 3-in-1 design for mulching, rear bagging, or side discharging. This flexibility allows you to adapt to different yard conditions without changing equipment. The listing also notes a vertical storage feature, which can save up to 70% of garage space. This compact footprint is useful for homeowners with limited storage areas. The finish is green, matching the brand's standard aesthetic. According to the listing, the dual battery port design allows one battery to charge while the other powers the mower, reducing downtime during larger jobs.
Setup and everyday use guide
You start by charging the included 5.0 Ah battery using the provided charger. The listing notes that the mower works with 75+ Greenworks 40V tools, so you can use existing batteries if you have them. This dual battery port design allows you to store one battery while the other powers the unit. You save trips to the garage by swapping batteries rather than carrying the whole tool.
The mower is a push model with no self-drive mechanism. You control the speed by walking. The 21-inch steel deck provides a moderate cutting swath. This width helps you cover ground faster than narrower models. The brushless motor delivers torque for consistent cutting. It also operates quietly and offers longer life than brushed alternatives.
You adjust the cutting height using the single-lever system. The listing specifies a maximum height of 33.1 inches. You can choose between three discharge options: mulching, rear bagging, or side discharge. This 3-in-1 design lets you handle different grass conditions. Mulching returns nutrients to the soil. Bagging collects clippings for disposal. Side discharge is useful for longer grass.
When you finish mowing, you can store the mower vertically. This feature uses up to 70% less space in your garage. The 62-pound weight makes it manageable to lift and store. The 3-year limited warranty covers both the tool and the battery. This provides dependable ownership for medium-sized lawns. You get a practical tool for regular maintenance without complex setup.
What You Need Before Buying
You already have the mower and a 5.0 Ah battery in the box. That setup handles most small to medium lawns. However, the 60-minute runtime is a soft limit. If your yard is larger or the grass is thick, you will need a second battery. The dual battery port helps, but you must buy that extra pack separately. Check your existing Greenworks 40V tools. This mower shares the same battery ecosystem. If you own trimmers or blowers, you can swap batteries. This saves money and reduces clutter. Keep the steel deck clean after use. Grass clippings stick to steel and cause rust if left wet. Store it vertically to save garage space. This model fits buyers who want a simple push mower. It suits those who already own Greenworks tools. Skip it if you need self-propulsion or a wider cut. Other options in this guide offer different deck widths or drive types for larger properties.
Check before you buy
- Verify you have a second 40V battery for larger yards
- Check if your existing Greenworks 40V tools share batteries
- Ensure your garage has vertical storage space for the mower
- Confirm your lawn size fits within the 60-minute runtime limit

Frequently asked questions
Does the Greenworks 40V 21-inch mower have a mulching kit included?

This ensures you know exactly what tools are available for your grass management needs right out of the box.
How heavy is the Greenworks 40V 21-inch push mower?
The mower weighs 62 pounds. This weight comes from the durable steel deck and the motor assembly. While this makes the unit sturdy, it also means you must push it manually. The 62-pound mass provides stability but requires physical effort to maneuver across your lawn.
What is the cutting width of this Greenworks mower?
The cutting width is 21 inches. This measurement refers to the steel deck size that clears grass in a single pass.

Is the Greenworks 40V mower suitable for large lawns?
This model is best for medium lawns. The 5.0 Ah battery provides up to 60 minutes of runtime, which may not suffice for very large properties. If your yard exceeds this capacity, you might need a second battery or a more powerful model. The 21-inch deck is optimized for average-sized spaces.
Can I store this mower vertically?
Yes, this mower is designed for vertical storage. The product data highlights this feature as a key benefit for homeowners with space constraints. You can hang or lean the unit upright to save floor space in your garage or shed. This design maximizes storage efficiency without compromising the steel deck's durability.
