Quick Verdict
The Ryobi 40V HP Brushless is the electric mower that proves you don't need to spend $700+ to ditch gas. At $399 with battery and charger, it delivers a clean 21-inch cut, reliable self-propulsion, 48 minutes of runtime, and features like LED headlights and cross-cut capability that pricier mowers skip. It won't match the EGO Select Cut on raw power or runtime, but for budget-conscious homeowners with 1/4 acre yards, it hits the sweet spot between price and performance that no other mower touches.
Best for:
- Budget-conscious homeowners under $400
- 1/4 acre yards with standard grass conditions
- Anyone already invested in the Ryobi 40V platform
Not ideal for:
- Yards over 1/3 acre (runtime limitation)
- Frequently thick or wet grass (need more power)
- Lawn perfectionists who want multi-blade systems
Overview: The $399 Sweet Spot
The electric mower market has a gap. Below $300, you get push mowers with brushed motors and short battery life. Above $600, you get premium machines like the EGO Select Cut with features most homeowners will never fully use. The Ryobi 40V HP Brushless sits right in the middle — and that's exactly where most buyers should be looking.
At $399, you get a brushless motor (more efficient, longer lifespan than brushed), self-propelled rear wheel drive, a 21-inch steel deck, 3-in-1 functionality (mulch, bag, side discharge), LED headlights, cross-cut capability, and a 6.0Ah battery with charger. That feature list would have been unthinkable at this price two years ago.
Ryobi has always been the value play in power tools, and their 40V outdoor lineup follows the same playbook: give homeowners 90% of the performance at 50-60% of the premium price. This mower is the clearest expression of that strategy.

Cut Quality: Punching Above Its Weight
The HP (High Performance) brushless motor is the key upgrade over Ryobi's standard 40V mowers. Brushless motors deliver more torque per watt, generate less heat, and last significantly longer than brushed alternatives. In practical terms, the blade spins faster and maintains RPM better under load — meaning it doesn't bog down when you hit a thick patch.
The 21-inch steel deck provides a clean, even cut across all seven height positions (1.5" to 4"). For standard weekly mowing on Bermuda, fescue, or Kentucky bluegrass, the cut quality is genuinely good — not "good for the price," just good. Stripes are clean, edges are sharp, and the deck clears clippings efficiently.
The 3-in-1 system gives you flexibility based on conditions. Mulching works well for regular dry mowing — clippings are chopped fine enough to disappear into the lawn. Bagging is solid for overgrown grass or fall cleanup. Side discharge handles those rare situations where you just need to get through tall growth quickly without clogging.
Where it falls short compared to the EGO Select Cut is on thick, wet grass. Without a dedicated high-lift blade option, the Ryobi can clump in heavy conditions. The solution is simple — mow more frequently or raise the height and make two passes — but it is a real limitation if your lawn grows fast in spring.
Battery and Runtime
The included 6.0Ah 40V battery provides up to 48 minutes of runtime per Ryobi's rating. Real-world numbers depend on conditions, but here is what you can expect:
Real-World Runtime by Condition
For a typical 1/4 acre suburban lawn mowed weekly, the 6.0Ah battery is sufficient. You will finish with runtime to spare. Push beyond 1/3 acre or let the grass get overgrown, and you'll be watching the battery indicator more than the lawn.
Charging takes roughly 90 minutes from empty to full with the included charger. That is slower than EGO's rapid charger (40 minutes), but perfectly fine if you charge overnight or between mowing sessions. If you need more runtime, a second 6.0Ah battery runs about $130 — and that battery also powers every other tool in the Ryobi 40V lineup.
Battery Tip
The brushless motor is noticeably more battery-efficient than the brushed motor in Ryobi's cheaper 40V mowers. If you're choosing between the HP Brushless and the standard brushed model, the extra runtime per charge alone justifies the price difference — you get roughly 15-20% more mowing time from the same battery.
The Ryobi 40V Platform: 40+ Tools, One Battery
Ryobi's biggest advantage isn't any single product — it's the platform. The 40V battery system powers over 40 outdoor tools, and Ryobi's exclusive partnership with The Home Depot means everything is readily available and competitively priced. This mower is an entry point into that ecosystem.
Yard Essentials
- String trimmers and edgers
- Jet fan leaf blowers (550+ CFM)
- Hedge trimmers
- Pole saws and pruners
Beyond the Lawn
- 14-inch chainsaw
- Snow blower (20-inch)
- Pressure washer (1,500 PSI)
- Expand-It attachment system
The Expand-It attachment system deserves special mention. One power head accepts multiple attachments — trimmer, edger, pole saw, cultivator, and more — so you buy one motor and swap attachments as needed. It's the most cost-effective way to build out a full yard care toolkit.
Compared to EGO's 70+ tool ecosystem, Ryobi's 40+ tools is smaller on paper. But Ryobi's tools are consistently 30-50% cheaper, and for typical homeowner use (not commercial landscaping), the performance gap is minimal. You're getting a reliable tool ecosystem at a price that makes it practical to actually buy multiple tools.
Standout Features at This Price
LED Headlights
Front-mounted LEDs let you mow in low-light conditions — early morning, late evening, or overcast days. This is a feature that many $600+ mowers skip entirely. For California homeowners mowing after work during shorter winter days, it extends your usable mowing window by a couple hours. Since electric mowers are quiet enough for evening use, the headlights actually matter.
Cross-Cut Capability
The blade cuts in both forward and reverse, which sounds minor until you use it. In tight corners, around flower beds, and near fence lines, being able to back up and re-cut without repositioning the entire mower saves real time. It also means you can do quick touch-ups without turning around for another full pass.
Foldable Handle
The handle folds down for vertical storage, reducing the mower's footprint dramatically. In a crowded garage or small shed, this is the difference between the mower fitting and not fitting. It also makes it easier to load into a car trunk if you mow at a second property.

Ryobi 40V vs EGO Select Cut vs Greenworks 80V
The three main contenders in the self-propelled electric mower space. Here is how they stack up:
| Feature | Ryobi 40V HP | EGO Select Cut XP | Greenworks 80V 21" |
|---|---|---|---|
| Price (kit) | $399 | $799 | $499 |
| Motor | 40V HP Brushless | 56V Brushless | 80V Brushless |
| Battery | 6.0Ah | 10.0Ah | 4.0Ah |
| Runtime | 48 min | 60 min | 45 min |
| Deck | 21" steel | 21" steel | 21" steel |
| Self-Propelled | Rear wheel, variable | Rear wheel, variable | Rear wheel, variable |
| Weight | ~57 lbs | 77.2 lbs | ~63 lbs |
| LED Headlights | Yes | No | No |
| Cross-Cut | Yes | No | No |
| Blade System | Standard single | Select Cut (3 blades) | Standard single |
| Platform Tools | 40+ | 70+ | 30+ |
Ryobi vs EGO: The Value Argument
The EGO Select Cut XP is objectively a better mower — bigger battery, longer runtime, the multi-blade system, a larger tool ecosystem. But it costs exactly twice as much. The question is whether those upgrades are worth $400 to you. If you have a large yard, deal with tough grass regularly, or already own EGO tools, yes. If you have a standard 1/4 acre lawn and mow weekly, the Ryobi gets the job done for half the money.
Ryobi vs Greenworks: The Closest Match
The Greenworks 80V sits between Ryobi and EGO on price ($499) and offers a higher voltage motor. However, the Ryobi counters with LED headlights, cross-cut capability, a larger battery capacity (6.0Ah vs 4.0Ah), lighter weight, and a bigger tool platform. The Greenworks 80V has more raw cutting power, but the Ryobi has more features and better battery life at a lower price. For most homeowners, the Ryobi is the smarter buy.
Budget Analysis: 5-Year Cost of Ownership
The upfront price tells only part of the story. Here is what the Ryobi 40V actually costs to own versus a comparable gas mower over five years:
Ryobi 40V HP Brushless
~$440 total- Mower (with battery + charger)$399
- Electricity (5 years)~$15
- Replacement blade (year 3)~$25
- Oil, gas, spark plugs, filters$0
Comparable Gas Self-Propelled
~$700-900 total- Mower$350-450
- Gas (5 years, ~3 gal/season)~$90-120
- Oil changes (annual)~$50
- Spark plugs, air filters, tune-ups~$80-120
- Blade sharpening or replacement~$60-80
- Carburetor service (year 3-4)~$50-80
Over five years, the Ryobi saves $260-460 in total ownership costs compared to a gas equivalent. And that doesn't factor in your time — no gas station trips, no oil disposal, no winterization, no pulling a starter cord 15 times on a cold morning. The maintenance for the Ryobi is effectively: charge the battery and replace the blade every 2-3 years. That's it.
Pros and Cons
Pros
- Best value self-propelled electric mower at $399
- HP brushless motor — more torque and longer life
- LED headlights for low-light mowing
- Cross-cut capability saves time in tight areas
- Only ~57 lbs — lightest in its class
- 40+ tool Ryobi 40V platform compatibility
- 3-in-1: mulch, bag, or side discharge
- Foldable handle for compact garage storage
- Zero maintenance — no gas, oil, or tune-ups
Cons
- 48-min runtime limits yard size to ~1/4 acre
- Struggles with very thick or wet grass
- Single blade — no multi-blade system like EGO
- Charger is slower (90 min vs EGO's 40 min)
- Bag is average size — fills quickly when bagging
- No app or Bluetooth connectivity
- Plastic deck components feel less premium
Final Verdict
The Ryobi 40V HP Brushless is the electric mower we recommend for budget-conscious homeowners. At $399, it delivers the core features that matter — brushless motor, self-propelled drive, 21-inch steel deck, 3-in-1 versatility — and adds LED headlights and cross-cut capability that pricier competitors skip. The Ryobi 40V platform gives you an affordable path to replace every gas tool in your garage.
It is not the most powerful electric mower. The 48-minute runtime and single blade system mean it is best suited for 1/4 acre yards with regular weekly mowing. If you have a larger yard, deal with tough grass frequently, or want the absolute best cut quality, the EGO Select Cut XP at $799 is worth the upgrade. But for the majority of suburban homeowners who just want to mow their lawn efficiently without gas-engine hassle, the Ryobi hits the perfect balance of price and performance.
Bottom line: if your budget is under $400 and your yard is under 1/3 acre, this is the self-propelled electric mower to buy in 2026.

Browse All ReviewsFrequently Asked Questions
How long does the Ryobi 40V lawn mower run on a single charge?
With the included 6.0Ah battery, the Ryobi 40V HP Brushless mower runs for up to 48 minutes. Real-world runtime on average suburban grass is typically 35-45 minutes depending on grass thickness, self-propelled speed, and whether you are mulching or bagging. That comfortably covers most 1/4 acre yards.
Is the Ryobi 40V mower battery compatible with other Ryobi tools?
Yes. The 40V 6.0Ah battery works with all 40+ tools in the Ryobi 40V platform, including string trimmers, leaf blowers, hedge trimmers, chainsaws, and pressure washers. If you already own Ryobi 40V tools, you can buy the mower as tool-only and use your existing batteries.
Can the Ryobi 40V mower handle thick or wet grass?
The HP brushless motor delivers more torque than standard brushed motors, so it handles moderately thick grass well. For very thick or wet grass, raise the cut height and make two passes. It will not match the raw cutting power of a premium mower like the EGO Select Cut with its high-lift blade, but for regular weekly mowing it performs reliably.
How does the Ryobi 40V mower compare to the EGO Select Cut?
The EGO Select Cut XP ($799) has a larger battery (10.0Ah vs 6.0Ah), longer runtime (60 vs 48 min), the multi-blade Select Cut system, and a bigger tool ecosystem (70+ vs 40+ tools). The Ryobi ($399) costs half as much, weighs 20 lbs less, and adds LED headlights and cross-cut capability. For budget-conscious homeowners with 1/4 acre yards, the Ryobi delivers 85% of the performance at 50% of the price.
Does the Ryobi 40V self-propelled mower work on hills?
Yes. The variable-speed rear wheel drive handles moderate slopes well. You can increase the speed for uphill sections and slow it down for flat areas. At 57 lbs with battery, it is lighter than many competitors, which makes it easier to maneuver on inclines. For very steep hills, the lighter weight is actually an advantage over heavier mowers.
What does the cross-cut feature do on the Ryobi mower?
Cross-cut capability means the mower can cut in both forward and reverse directions. This is useful for tight spots, corners, and areas where you need to back up and re-cut without lifting the mower. It saves time on complex lawn layouts with flower beds, trees, and obstacles.
