If you’re deciding between the Greenworks 40V cordless mower and the Ryobi 40V cordless mower, you’re really choosing a battery ecosystem as much as you’re choosing a lawn mower. Both brands deliver solid performance for suburban lawns, offer a wide range of 40V tools, and keep improving runtime and cut quality year after year.
The trick is matching the right model and battery setup to your lawn size, grass type, and how you like to mow. We’ve tested and wrenched on enough battery mowers to know the differences that actually matter, things like deck materials, blade design, charger speeds, and how well the motors handle wet growth. Below, we break it down clearly so you can make the call with confidence.
Quick Comparison Snapshot
What We’re Comparing
We’re comparing mainstream 40V self-propelled and push models from Greenworks and Ryobi, the ones most homeowners consider in the 19–21 inch range, with brushless motors and dual-battery bays on select models. We’re focusing on:
- Battery platform depth (other tools you can run) and charger speeds
- Cutting performance (bagging, mulching, side discharge)
- Runtime and power management
- Ergonomics and storage
- Durability, maintenance, and warranty
- Price and long-term value
Who Each Brand Suits Best
- Greenworks 40V: Great for users who want value-forward kits, straightforward controls, and strong mulching in a light-to-midweight package. Greenworks often nails the balance of price, features, and decent runtime, especially in the 20–21 inch brushless models.
- Ryobi 40V: A strong pick if you already own Ryobi 40V tools or want plentiful retail availability. The higher-end HP brushless mowers bring good torque and a wide accessory ecosystem. Ryobi appeals to DIYers who like ready access to batteries, blades, and service via big-box stores.
Key Strengths And Trade-Offs At A Glance
- Greenworks strengths: Competitive pricing on kits, dual-battery bays on many models (auto-switching for longer cuts), solid mulching, easy vertical storage. Trade-offs: Charger selection can be slower unless you buy the rapid charger: some models use lighter polymer decks (good for weight, less so for long-term abuse).
- Ryobi strengths: Broad battery options, widely available parts, and strong higher-tier performance (HP brushless). Trade-offs: Some models weigh more and may feel bulkier: base kits can include lower-amp chargers unless you step up to rapid.
In short, Greenworks 40V cordless mowers often win on value and simplicity, while Ryobi 40V cordless mowers tend to win on ecosystem breadth and easy retail support.
Battery Platform And Charger Ecosystems
Battery Options And Amp-Hour Choices
Both platforms offer a healthy spread of 40V batteries. Typical capacities include 2.0Ah, 4.0Ah, and 5.0–6.0Ah packs, with higher-capacity options available for extended runtime. For most 1/4–1/2 acre lawns, a pair of 4.0–6.0Ah batteries hits the sweet spot. Larger packs add runtime but also weight, which can slightly affect maneuverability and the mower’s balance.
Cross-Compatibility Within Each Brand
- Greenworks 40V batteries work across the brand’s 40V lineup (mowers, string trimmers, blowers, etc.). You can’t mix 40V with their 24V or 60V lines, platforms are separate.
- Ryobi 40V batteries are compatible within Ryobi’s 40V tools. As with Greenworks, 40V is distinct from Ryobi’s 18V ONE+ line. If you’re already invested in one ecosystem, staying in it normally maximizes your value.
Charging Speed And Dual-Port Behavior
- Greenworks chargers include standard and rapid models. Rapid chargers substantially cut recharge times, which matters if you want to mow, recharge over lunch, and finish the yard the same afternoon. Many Greenworks 40V mowers include two battery bays that auto-switch under load for extended runtime, but charging still happens on the charger, not the mower.
- Ryobi’s 40V chargers range from standard to rapid as well. Dual-port chargers are typically sequential, not simultaneous. As with Greenworks, make sure the kit you buy includes a charger that matches your expectations, some bundle a slower unit to keep kit prices down.
Bottom line: for both brands, a rapid charger and two mid-to-large packs are the best quality-of-life upgrade you can make for 40V mowing.
Cutting Performance And Deck Options
Deck Sizes, Blades, And Height Adjustments
- Deck sizes: You’ll commonly find 19–21 inch decks in both lineups. A 21 inch deck reduces passes on rectangular lawns: smaller decks weave better around landscaping.
- Deck materials: Greenworks offers both polymer and steel decks in 40V. Polymer keeps weight and corrosion down, while steel tends to feel more planted and can take more knocks. Ryobi also offers polymer and steel options in 40V. If you routinely bump curbs or mow along stone edging, steel earns its keep.
- Blades: Both brands use single-blade designs on most 21 inch models, with high-lift and mulching profiles available for certain SKUs. Ryobi’s premium HP brushless mowers often ship with aggressive blade profiles that favor bagging suction. Greenworks tends to deliver a well-balanced mulching cut on its brushless 21 inch decks.
- Height adjustment: Expect one-lever, 7-position height adjustment on mid/high-tier models from both brands. Range typically spans about 1.25–4 inches, suitable for cool- and warm-season grasses.
Bagging, Mulching, And Side Discharge
- Mulching: Greenworks 40V mowers have a strong reputation for fine mulch with even clippings distribution, great for weekly maintenance. Ryobi also mulches well, with certain models prioritizing airflow for bagging. If you rarely bag, Greenworks often feels a touch more effortless in mulch mode.
- Bagging: Ryobi’s airflow and bag design can give it a small edge in pickup, especially with a sharp high-lift blade. Greenworks bags capably too: consider a high-lift blade upgrade if you want cleaner stripes and leaf pickup.
- Side discharge: Both brands support side discharge on many models, but not all. If you regularly cut taller growth and like to windrow clippings, verify the specific mower includes the chute.
Wet Grass And Overgrowth Handling
Battery mowers don’t love wet grass, but the higher-end brushless units from both brands will get it done with patience. Ryobi’s HP brushless models feel a touch more assertive when hitting wet patches or modest overgrowth, holding blade speed better. Greenworks counters with smooth load management that avoids abrupt stalls. In honest terms, for truly neglected lawns, a second pass or higher initial cut is smart, regardless of brand. Keeping blades sharp makes a bigger difference than most people expect.
Runtime, Power Management, And Efficiency
Real-World Runtime Scenarios
Marketing runtimes vary, but real-world mowing on 40V with a 21 inch deck typically looks like this:
- Light weekly cut, dry grass: ~35–50 minutes per 4.0–5.0Ah battery
- Moderate growth or mixed terrain: ~25–40 minutes per 4.0–5.0Ah battery
- Heavy, damp grass: ~15–25 minutes per 4.0–5.0Ah battery
Two batteries and a dual-bay mower (auto-switching) can comfortably finish 1/4 acre in one go. For 1/2 acre, plan on two larger packs or a mid-mow recharge with a rapid charger.
Smart Load-Sensing And Throttle Modes
Both brands use load-sensing to adjust blade speed as conditions change. Greenworks’ tuning tends to be gentle and quiet, ramping up smoothly as the mower meets resistance. Ryobi’s higher-tier 40V HP brushless systems punch up blade speed a bit more aggressively for suction and cut continuity. Either way, you save energy when the grass is easy and get more power when it’s not. If your lawn varies a lot across zones, this feature pays off in both runtime and cut quality.
Cold Weather And Battery Care
Lithium batteries prefer room temperature. For best performance:
- Store batteries indoors when temps drop below freezing or soar in summer.
- Warm a cold battery to about room temp before charging.
- Don’t leave packs on the charger long-term: top off before mowing instead.
- Clean the mower deck and keep blades sharp, less load equals longer runtime.
These habits extend battery life and keep any 40V mower feeling fresh season after season.
Ergonomics, Maneuverability, And Storage
Weight, Balance, And Push Effort
Greenworks 40V mowers with polymer decks are typically lighter and easier to pivot around beds and trees. Ryobi can feel a bit heavier, especially on steel-deck or premium HP units, but the added mass can help the mower track straighter and reduce bounce across uneven patches. Self-propel drives on both brands have improved, look for variable-speed controls so you can match your walking pace.
Handles, Controls, And Safety Features
Both brands use folding, height-adjustable handles with safety bail bars. We like that Greenworks often keeps the control layout simple and unobtrusive. Ryobi commonly uses a larger control panel and a more pronounced speed dial on self-propel models, which some of us prefer for fine-tuning pace. In either case, check for:
- Multiple handle height positions
- Easy-to-read battery indicators
- Intuitive blade start and self-propel engagement
- A positive deck height lever that doesn’t drift
LED headlights are a nice-to-have for low light. Safety interlocks are standard and operate similarly across both brands.
Vertical Storage And Foldability
Both Greenworks and Ryobi promote vertical storage on many 40V models, huge space saver in a garage or shed. The key is a sturdy hinge and a secure latch so the handle doesn’t slip. Greenworks’ lightweight decks make wall storage less of a wrestling match. Ryobi’s heavier builds still store vertically but may take two hands to tip if you’ve got a full bag attached (empty the bag first, always). Clean the deck before storing to prevent odors and buildup.
Build Quality, Durability, And Maintenance
Materials, Protection, And Weather Resistance
- Decks: Polymer decks resist corrosion and are quieter: steel decks feel more rugged against impacts. Both brands offer both options, choose based on how tough your mowing environment is.
- Motor protection: Brushless motors are sealed and generally shrug off normal moisture. Don’t hose the motor directly: tip the mower carefully and wipe down. Both brands caution against operating in heavy rain.
- Wheels and axles: Look for ball-bearing wheels on mid/high-tier models for smoother rolling and longer life. Ryobi often fits larger rear wheels on select models, helping over ruts and roots.
Maintenance Tasks And Parts Availability
Routine tasks are simple on both:
- Sharpen/replace blade each season (or more often if you hit sand/rocks)
- Clear the deck after mowing
- Inspect and tighten handle hardware
- Keep batteries clean and contacts free of debris
Parts access is where Ryobi’s big-box presence can be handy, bags, blades, and chargers are usually easy to find locally. Greenworks parts are widely available online and through authorized retailers. Either way, keep a spare blade on hand: switching to a high-lift blade for spring cleanup can boost bagging.
Reliability, Warranty, And Support
Both brands have solid reliability in the mid-tier brushless range. Warranty terms vary by model and retailer, but typically you’ll see around 3–5 years on tools and around 3 years on batteries. Check the specific SKU before you buy. Support-wise, Ryobi benefits from in-store service channels at major retailers. Greenworks offers responsive online and phone support with clear parts diagrams and documentation.
Price, Value, And Long-Term Ownership
Tool-Only Versus Kit Pricing
- Greenworks 40V kits often undercut comparable Ryobi kits on price, especially during seasonal promos. You can usually get a 20–21 inch brushless Greenworks kit with two mid-size batteries at a compelling price.
- Ryobi 40V kits sometimes cost a bit more for similar specs, but availability is excellent and retailer bundle deals can be strong, especially if you time your purchase around spring or holiday sales.
If you already own batteries in either platform, tool-only purchases can save a lot. Just confirm amp-hour needs so you’re not underpowered.
Accessory Ecosystem And Upgrades
- Blades: Both brands offer OEM replacement and high-lift options: third-party blades exist, but stick with spec’d sizes and bore patterns.
- Bags: Easy to replace for both: Ryobi’s in-store stock is a convenience edge.
- Chargers: Upgrading to a rapid charger is worth it no matter which platform you pick. Dual-port chargers are convenient but usually charge sequentially.
- Other tools: This is where long-term value compounds. Greenworks 40V and Ryobi 40V both include trimmers, blowers, hedge trimmers, chainsaws, and more. If you plan to expand, pick the ecosystem that covers your future tool list.
Total Cost Of Ownership And Resale Value
Consider battery replacements after several years: lithium packs naturally age. Because Ryobi’s 40V install base is large, resale of tools and packs is often straightforward. Greenworks also holds value well, particularly the brushless 21 inch models with steel decks. Over 5–7 years, the platform with the charger and batteries that match your yard will typically be the cheapest to own, even if the kit price wasn’t the absolute lowest on day one.
Recommendations By Lawn Size And Use Case
Small Yards (Up To 1/4 Acre)
- Pick a 19–20 inch deck to keep it nimble. One 4.0–5.0Ah battery may cover a weekly cut, but two is ideal so you’re never stuck.
- Greenworks 40V: A value-friendly 20–21 inch brushless model with a polymer deck is easy to store and great for mulching.
- Ryobi 40V: A compact HP brushless with a rapid charger makes quick work of small lawns and handles leaf pickup well with a high-lift blade.
Medium Yards (1/4 To 1/2 Acre)
- Go 21 inch with self-propel and dual-battery bays. Two 4.0–6.0Ah packs plus a rapid charger is the winning formula.
- Greenworks 40V: Look for a brushless 21 inch with auto battery switching and vertical storage. Strong mulching and quiet operation shine here.
- Ryobi 40V: Consider an HP brushless 21 inch for a bit more torque and bagging performance, especially if you cut every 10–14 days or deal with mixed turf density.
Challenging Lawns And Special Cases
- Taller or wet grass: Ryobi’s higher-tier HP brushless models feel slightly more assertive through wet patches: pair with a high-lift blade for bagging-heavy routines.
- Lots of obstacles or slopes: Greenworks’ lighter polymer-deck units are easier to muscle around gardens and up short slopes. Keep the self-propel speed low for control.
- Noise sensitivity and evening mowing: Both are quiet compared to gas. Greenworks often sounds a touch smoother due to gentle load ramping: headlights on either help at dusk.
- Storage-limited garages: Both do vertical storage: Greenworks’ lighter frames are a little simpler to flip and tuck in tight spots.
Conclusion
So, Greenworks 40V cordless mower vs Ryobi 40V cordless mower, who wins? It depends on what you value. If you want a sharp price-to-performance ratio, easy storage, and excellent mulching for weekly cuts, Greenworks is hard to beat. If you prize a huge retail footprint, slightly stronger bagging on higher-end models, and broad accessory availability, Ryobi makes a compelling case.
Our take: match the mower to your lawn size and your charging plan. Buy a rapid charger, keep two healthy batteries, and sharpen the blade each season. Do that, and either 40V platform will give you a clean, low-stress cut for years, no gas, no fuss, just a better Saturday.
