What Sets It Apart
Key specification highlights based on our analysis.
21.0-Inch Cutting Deck
Wide cutting path reduces passes (walk-behind avg: 18.0 in)
Steel Cutting Deck
Durable steel deck for long-term use
3-in-1 Discharge
Mulch, side discharge, and rear bag (59 of 364 mowers have all three)
80V Battery System
High-voltage platform for more power (database avg: 38.1V)
Why We Recommend It
- 01.
80V / 6.0Ah battery system provides high-voltage power comparable to gas engines , more than twice the average cordless mower voltage of 38.1V
- 02.
21-inch cutting deck is wider than the 18-inch walk-behind average, meaning fewer passes to cover the same area
- 03.
Brushless motor extends both battery runtime and long-term motor lifespan compared to brushed alternatives
- 04.
Versatile 3-in-1 discharge system , mulching returns nutrients to the lawn, side discharge handles heavy growth, and rear bag keeps clippings collected
- 05.
Central single-lever 6-position cutting height adjustment (1.6-4.0 inches) makes it easy to dial in the right cut for your grass type
Considerations
- 01.
Approximately 40-minute runtime per charge may require a mid-session swap for yards approaching or exceeding half an acre
- 02.
At 55 lbs, it's on the heavier side for a push mower, which could be tiring on larger flat areas without self-propulsion
- 03.
Assembly is required out of the box, adding a step before first use

Power & Performance
The 80V brushless motor is the headline here , at more than double the database average of 38.1V for battery mowers, this system delivers torque and cutting consistency that competes directly with entry-level gas engines. The brushless design specifically means less energy lost to friction, translating to more efficient power delivery through each blade rotation and longer motor life over years of use.
In practical terms, this mower should handle moderately thick grass, slightly overgrown lawns, and a mix of grass types without bogging down the way lower-voltage cordless mowers can.
Cutting System
The 21-inch steel cutting deck offers a wider cutting path than the 18-inch walk-behind average, directly reducing the number of passes needed to cover your lawn. Steel construction ensures the deck holds up to debris strikes and years of seasonal use better than plastic alternatives.
The 6-position central height adjustment spans 1.6 to 4.0 inches, covering close-cropped putting-green heights up through taller fescue or zoysia cuts, and the single-lever central adjustment means you change all four wheels at once rather than adjusting each corner separately.
Drive & Handling
This is a push mower, so all forward movement comes from the operator , there's no self-propelled drive assist. At 55 lbs, it's manageable on flat ground but will require more effort on inclines or large areas.
The rear-wheel drive configuration (passive, following the operator) provides stable straight-line tracking on flat terrain. The push-button start eliminates the physical strain of a pull cord, which is a genuine quality-of-life improvement for users with limited upper body strength or mobility concerns.
Battery / Fuel
The included 80V 6.0Ah battery and charger are bundled in the box, so there are no additional purchases needed to get started. The 6.0Ah capacity at 80V represents a substantial energy reserve , rated for approximately 40 minutes of continuous runtime, which translates to roughly 1/4 to 1/3 acre depending on grass conditions and mowing speed.
Because this is a battery-powered system, there is zero fuel investment, no oil to change, no spark plugs to replace, and no carburetor to clean , total cost of ownership over time is significantly lower than a comparable gas mower.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with yards up to about 1/3 acre who want the power of gas without fuel, oil changes, or pull-cord frustrations , the 80V brushless motor handles typical suburban lawns with ease
- ✓ Eco-conscious users seeking zero direct emissions and quieter operation compared to gas mowers, without settling for an underpowered battery system
- ✓ Anyone who hates mower maintenance , no spark plugs, no carburetor, no oil to change; just charge, press the push-button start, and mow
- ✓ Homeowners who want cutting flexibility, since the 3-in-1 discharge lets you mulch in summer, bag in fall, and side-discharge when the grass gets ahead of you
Not Ideal For
- ✕ Large property owners with half an acre or more , the 40-minute runtime may require recharging mid-session, disrupting workflow
- ✕ Users with hilly or uneven terrain who need a self-propelled drive system to assist on slopes; this is a push-only mower
- ✕ Those who need to mow immediately with no setup time , assembly is required before first use
Assembly is required and typically involves attaching the handle to the mower body and installing the rear bag , a straightforward process for most users that should take 15-30 minutes with basic tools.
Charge the 80V 6.0Ah battery fully before first use to condition the cells and get an accurate sense of your real-world runtime on your specific lawn
Attach the rear bag securely before your first mow and test all three discharge configurations (mulch plug, side chute, bag) so you're familiar with switching between them mid-session
Warranty terms should be verified directly with PowerSmart or the seller at time of purchase, as coverage terms can vary by retailer and region. PowerSmart generally offers product support through their official channels, and registering your mower after purchase is recommended to ensure full warranty eligibility.
FAQ
How long does the 80V 6.0Ah battery last on a single charge?
PowerSmart rates the included 6.0Ah battery at approximately 40 minutes of runtime. In practice, this covers most yards up to about 1/4 to 1/3 acre per charge, depending on grass thickness and mowing speed.
The brushless motor helps maximize battery efficiency compared to brushed-motor alternatives.
Is the PowerSmart 80V mower self-propelled or push only?
This is a push mower , there is no self-propelled drive system. You provide all forward movement manually.
At 55 lbs, it's manageable on flat terrain, but if you have slopes or a larger yard, you may want to consider a self-propelled model for reduced fatigue.
Does this lawn mower mulch, or does it only bag clippings?
It does both , and more. The 3-in-1 discharge system supports mulching (returning clippings to the lawn as fertilizer), rear bag discharge for collecting clippings, and side discharge for handling heavier or taller grass.
Only 59 out of 364 mowers in the category offer all three options, making this unusually versatile.
How hard is the push-button start to use compared to a gas mower pull cord?
Dramatically easier. The push-button start requires no physical yanking or priming , you press a button and the brushless motor engages immediately.
This is one of the most cited advantages of high-voltage cordless mowers over gas alternatives, especially for users with shoulder, arm, or grip issues.
What maintenance does the PowerSmart 80V cordless mower require?
Very little compared to gas mowers. There's no engine oil to change, no spark plugs to replace, no air filter to clean, and no fuel system to maintain.
Regular upkeep involves cleaning the underside of the deck after mowing, occasionally sharpening the blade, and storing the battery properly during the off-season.
Is 80V really that much better than a 40V or 60V battery mower?
Voltage is a key indicator of a battery mower's power ceiling , higher voltage means the motor can draw more energy per unit time, which translates to more torque and better performance in thick or wet grass. The 80V system here is more than double the 38.1V database average, putting it firmly in the high-performance cordless tier alongside brands like EGO and Greenworks Pro.
Bottom Line
The PowerSmart 80V 21-inch Brushless Cordless Mower is a strong pick for homeowners who want genuine gas-comparable cutting power without the fuel, fumes, or maintenance overhead of a traditional engine. The 80V brushless motor, wide 21-inch steel deck, and 3-in-1 discharge make it capable and versatile; the push-button start and zero-maintenance battery system make it easy to live with.
Users with large properties or steep hills will hit its limits, but for flat to gently rolling yards up to about 1/3 acre, it's a well-equipped cordless option.
Best for flat suburban yards up to 1/3 acre where zero-emissions, low-maintenance mowing and cutting flexibility are the priority.
Consider alternatives if you have steep slopes that need self-propelled assistance, or a yard larger than 1/3 acre where a 40-minute runtime will leave you short.
