Power & Performance
The 80V battery system is the headline spec here, operating at more than double the voltage of the average cordless mower in its class (38.1V database average). Paired with a 6.0Ah battery, this translates to sustained motor output that handles typical residential grass types , fescue, Bermuda, Kentucky bluegrass , without bogging down mid-row.
For moderately thick or slightly wet grass, the high-voltage design maintains blade speed better than lower-voltage competitors.
Cutting System
The 21-inch rotary steel deck offers a wider cutting path than the 18-inch walk-behind average, reducing the total number of passes needed and improving mowing productivity on larger lawns. The steel deck construction provides durability over plastic alternatives and resists denting from debris.
Five cutting height positions adjusted at the individual wheel level give you flexibility from a close trim to a taller, drought-stress-friendly cut, and the 3-in-1 discharge lets you switch between mulching, side discharge, and rear bagging to match your lawn's needs.
Drive & Handling
The rear-wheel drive self-propelled system provides better grip going uphill compared to front-wheel-drive designs, where the front wheels can lose traction when the deck rises on slopes. At 60 lbs, the mower is heavier than some cordless alternatives, but the self-propelled drive compensates on flat to gently rolling terrain.
Handle height and grip design follow standard ergonomic conventions, though some users report the drive engagement lever requires some break-in before feeling smooth.
Battery / Fuel
The included 80V 6.0Ah lithium-ion battery is rated for approximately 40 minutes of runtime, with real-world reports ranging from 35 to 40 minutes depending on grass density and drive speed. The charger is included in the box, so there's no additional purchase required to get started.
Unlike gas mowers, there are no oil changes, air filter replacements, or carburetor cleanings , annual maintenance is minimal, making this an excellent low-maintenance lawn mower for homeowners who want a reliable season-to-season tool.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with medium to large yards (up to ~1/2 acre) who want the productivity of a wide 21-inch deck and self-propelled drive without gas maintenance
- ✓ Eco-conscious users who want zero direct emissions, quieter operation, and no trips to the gas station , the 80V battery design delivers power without the fumes
- ✓ Homeowners with gently sloped lawns who need rear-wheel drive traction that front-wheel-drive cordless mowers can't reliably provide
- ✓ Lawn care enthusiasts who want maximum discharge flexibility , mulching for lawn health, side discharge for speed, or rear bagging for a clean finish
Not Ideal For
- ✕ Owners of very large properties (over 1/2 acre) who need continuous mowing , the 35-40 minute runtime may require a recharge mid-session without a spare battery
- ✕ Users with heavily overgrown, very thick, or steep terrain who may need a more powerful commercial-grade gas or 120V battery platform
- ✕ Buyers who want a plug-and-play, zero-assembly experience , this mower requires setup and some mechanical confidence to get started
Assembly is required and typically involves attaching the handle, installing the grass bag, and charging the battery before first use , most users complete this in 20-30 minutes. Some customers report a smooth out-of-box experience, while a smaller number note challenges getting the mower running initially.
Fully charge the 80V battery before first use to ensure the battery management system calibrates correctly and you get maximum runtime from the start
Check that the blade engagement and self-propelled drive lever are properly connected during handle assembly , loose cable routing is a common source of early operational issues
PowerSmart typically offers a limited warranty on their cordless mower lineup; verify current warranty terms directly with PowerSmart or the retailer at time of purchase, as coverage periods and conditions can vary by product and region.
FAQ
How long does the 80V battery last on a single charge?
PowerSmart rates the 80V 6.0Ah battery at approximately 40 minutes of runtime. Real-world customer feedback puts actual runtime closer to 35-40 minutes depending on grass thickness, mowing speed, and how aggressively the self-propelled drive is used.
For yards under 1/3 acre, one charge is typically sufficient per session.
Is the PowerSmart 80V lawn mower truly self-propelled, and how well does it work on hills?
Yes , it uses a rear-wheel drive self-propelled system, which is better suited for hills and slopes than front-wheel-drive designs because the rear wheels maintain contact and traction as the mower climbs. For gently to moderately sloped yards, the rear-wheel drive design handles the terrain well, though very steep inclines may still require extra effort or a more specialized machine.
Does the 22-inch PowerSmart mower mulch, bag, and side discharge?
Yes , the mower features a 3-in-1 discharge system supporting mulching, side discharge, and rear bagging. This flexibility is less common than it sounds: fewer than 1 in 6 mowers in this category offer all three options.
You can mulch clippings back into the lawn for nutrients, side-discharge for speed on overgrown areas, or rear-bag for a clean finish.
How does the PowerSmart 80V compare to gas mowers in terms of power?
The 80V battery platform is among the more powerful cordless systems available for residential mowers, delivering motor output comparable to a light to mid-range gas engine for typical lawn conditions. It won't match a high-torque commercial gas mower in dense or very thick turf, but for standard residential grass heights it performs on par , with the added benefits of no emissions, quieter operation, and near-zero maintenance.
What is the cutting deck size , is it 21 or 22 inches?
The mower is marketed as a 22-inch model but the actual cutting deck width is 21 inches , a common industry practice where the deck housing measurement is cited rather than the true blade cutting path. At 21 inches, it still cuts a wider swath than the 18-inch walk-behind average, meaningfully reducing the number of passes needed on larger lawns.
Does the PowerSmart 80V lawn mower come with the battery and charger included?
Yes , the package includes one 80V 6.0Ah lithium-ion battery and a compatible charger, so no additional purchases are required to start mowing. If you anticipate needing more than 35-40 minutes of continuous runtime, purchasing a second battery is worth considering for uninterrupted use on larger properties.
Bottom Line
The PowerSmart 80V 22" Self-Propelled Cordless Lawn Mower is a well-equipped, high-voltage battery mower that punches above its tier class with a wide 21-inch steel deck, genuine rear-wheel drive, and 3-in-1 discharge versatility. It's best suited for homeowners with medium to large, moderately sloped yards who want to eliminate gas maintenance entirely without sacrificing cutting productivity.
Buyers who need extended runtime on very large properties or who face heavily overgrown conditions should factor in a second battery or consider a higher-capacity alternative.
Best for medium-to-large suburban yards wanting powerful 80V cordless performance, self-propelled convenience, and zero-emissions mowing.
Consider alternatives if your yard exceeds 1/2 acre or requires more than 40 minutes of continuous mowing per session without a recharge break.
