Worx vs Greenworks: Which Cordless Mower Platform is Right for You?
Worx and Greenworks are two of the most popular brands in the cordless lawn mower market. Both offer reliable battery-powered solutions that eliminate gas and cords, but they approach the task from different angles. Worx focuses on compact, lightweight, and innovative designs like the foldable "Landroid" style mowers, while Greenworks emphasizes high-voltage power and longer runtime for larger properties.
This comparison breaks down the key differences between the two brands, focusing on their most popular models: the Worx WG779 40V 14-inch mower and the Greenworks 80V 21-inch mower. We analyze published specs, aggregated owner reviews from major retailers, and brand reliability to help you choose the right mower for your lawn.
Worx WG779 40V 14-Inch Cordless Lawn Mower
The Worx WG779 is a compact, lightweight mower designed for small to medium lawns. Its standout feature is the foldable design that allows it to be stored vertically, saving significant garage or shed space. It uses Worx's Power Share 40V battery platform, which is shared with over 100 other Worx tools.
Owner reviews consistently praise its maneuverability and ease of use. The 14-inch cutting width is ideal for tight spaces and intricate landscaping. However, the smaller deck means more passes are needed on larger lawns. The mower is push-only, which is fine for flat, small areas but can be tiring on slopes.
Pros
- Extremely compact vertical storage
- Lightweight at 29 lbs
- Shared battery platform with many tools
Cons
- Small 14-inch deck
- Not self-propelled
- Shorter runtime
Greenworks 80V 21-Inch Cordless Lawn Mower
The Greenworks 80V 21-inch mower is a full-sized, self-propelled machine built for medium to large lawns. Its 80V battery system delivers power comparable to a gas mower, and the 21-inch steel deck provides a wide cutting path. It comes with two 4.0 Ah batteries, offering ample runtime for most yards.
Owner reviews highlight its strong cutting performance, even in thick grass, and the variable-speed self-propelled drive makes mowing effortless on slopes. The build quality is solid, with a durable steel deck. The main downside is its weight (48 lbs) and larger footprint, which makes it less maneuverable in tight spaces and harder to store.
Pros
- Powerful 80V motor
- Self-propelled with variable speed
- Excellent runtime with two batteries
Cons
- Heavy and bulky
- Requires more storage space
- Higher price point
What to Check Before Buying a Cordless Lawn Mower
Before choosing between Worx and Greenworks, evaluate your specific needs against these key factors.
Lawn Size: For lawns under 1/4 acre, the Worx 14-inch mower is sufficient. For 1/4 to 1/2 acre, the Greenworks 21-inch mower is better. For larger lawns, consider a zero-turn or ride-on mower.
Terrain: If your lawn is flat, a push mower works. If you have slopes, a self-propelled model like the Greenworks is essential for ease of use.
Storage Space: If you have limited garage or shed space, the Worx foldable design is a game-changer. The Greenworks requires a standard floor footprint.
Battery Ecosystem: If you already own Worx or Greenworks tools, staying within the same battery platform saves money on additional batteries and chargers.
Mistakes to Avoid When Buying a Cordless Mower
Underestimating battery needs: A single 4.0 Ah battery may not be enough for a full mow on a medium lawn. Always check runtime estimates and consider buying a mower that comes with two batteries or has a compatible larger battery option.
Ignoring deck size: A 14-inch deck is great for small yards but will take significantly longer on a larger lawn. Match the deck size to your lawn's square footage to avoid frustration.
Forgetting about storage: Measure your storage space before buying. A bulky 21-inch mower may not fit in a narrow shed. The Worx foldable design is a clear winner for tight spaces.
Overlooking self-propulsion: On hilly or large lawns, a self-propelled mower is a worthwhile investment. Push mowers can be exhausting on slopes and over long distances.
FAQs
Which brand has better battery life, Worx or Greenworks?
Greenworks generally offers longer runtime due to its higher voltage (80V vs 40V) and larger battery capacities. The Greenworks 80V mower with two 4.0 Ah batteries can run for 45-60 minutes, while the Worx 40V typically runs for 30-40 minutes.
Is the Worx mower good for thick grass?
The Worx WG779 can handle normal grass but may struggle with very thick or wet grass due to its smaller motor and deck. The Greenworks 80V is much better suited for thick, dense lawns.
Can I use a larger battery on the Worx mower?
Yes, the Worx Power Share platform supports larger batteries (e.g., 6.0 Ah or 8.0 Ah) for extended runtime. However, the mower's performance is still limited by its 40V motor.
Which mower is easier to store?
The Worx WG779 is significantly easier to store. It folds vertically and stands upright, requiring very little floor space. The Greenworks 80V mower requires a standard horizontal storage footprint.
Are Greenworks batteries interchangeable with other tools?
Yes, Greenworks batteries are interchangeable across their 40V, 60V, and 80V platforms (with adapters). This allows you to use the same batteries for string trimmers, blowers, and chainsaws.
Which mower is better for a small lawn?
For a small lawn (under 1/4 acre), the Worx WG779 is the better choice due to its lightweight design, compact storage, and lower price. It is highly maneuverable in tight spaces.
Does the Greenworks mower come with a charger?
Yes, the Greenworks 80V 21-inch mower comes with a rapid charger. It typically takes about 60-90 minutes to fully charge a 4.0 Ah battery.
Is the Worx mower self-propelled?
No, the Worx WG779 is a push mower. Worx does offer self-propelled models in its 40V lineup, but the WG779 is not one of them.
Which brand has a better warranty?
Greenworks offers a 4-year warranty on its 80V mowers, while Worx provides a 3-year warranty. Both are solid, but Greenworks has the edge here.
Can I mulch with both mowers?
Yes, both the Worx WG779 and the Greenworks 80V mower offer mulching, bagging, and side discharge capabilities. They come with a mulching plug included.
Which mower is quieter?
Both are significantly quieter than gas mowers. The Worx is slightly quieter due to its smaller motor, but the difference is minimal in practice.
Which mower is better for slopes?
The Greenworks 80V self-propelled mower is much better for slopes because the drive system helps you push uphill. The Worx push mower can be difficult on inclines.
Our verdict
The Greenworks 80V 21-Inch Cordless Lawn Mower is the best overall pick for most homeowners due to its powerful motor, self-propelled drive, and excellent runtime. The Worx WG779 40V is the best budget and space-saving choice for small, flat lawns where storage is a premium.
