The Greenworks 80V 21-inch push mower (GLM801602) is the high-voltage value pick, typically around $398 with battery and charger. Its 80V brushless motor and up to 60 minutes of runtime give it strong power and endurance for a push mower, and easylawnmowing scored it 95/100. The trade-offs are 3-in-1 (no dedicated leaf mode) functionality and push-only operation, but for power-per-dollar it is a standout.

Real-World Performance
The Greenworks 80V 21-inch push mower (GLM801602) is the power-per-dollar value pick. easylawnmowing scored it 95/100 and summed it up plainly: if you want power and strength, this 80V mower has what you need. The 80V brushless motor is the highest voltage of any push mower in this list, and reviewers consistently praise it as a genuine gas alternative for flat-to-moderate lots up to a half acre.
Lawn Mower Review called it powerful with a good runtime and a complete kit at a really good price, while Essential Home and Garden highlighted the instant one-touch start and operation that is 16 times quieter than gas. It is push-only, so it is not the easiest on hills, but for cutting power on regular grass it punches well above its roughly $398 price.
Build Quality and Design
Greenworks built the GLM801602 around a 21-inch stamped-steel deck with a single-lever seven-position height adjustment from about 1.375 to 4 in and an instant one-touch start. The kit includes the mower, an 80V 4.0Ah battery, a rapid charger, and a grass collection bag, a complete package at the price.
It uses a 3-in-1 system, mulch, rear bag, and side discharge, which is one mode short of the 60V model's added leaf pickup. Build quality is solid for a value mower, backed by a 4-year tool-and-battery warranty. Buyers should note this is the older GLM801602 model; Greenworks' newer 80V SKUs carry the same look but cost considerably more, so the GLM801602 is the value sweet spot.
Battery Life and Power
The 80V system is the most powerful push platform here, and the included 4.0Ah battery delivers up to 60 minutes of runtime, the longest single-battery endurance of the push mowers in this list. That combination lets it handle a half-acre lot comfortably on one charge while powering through grass that lower-voltage mowers slow on.
Reviewers repeatedly cite the runtime-plus-power balance as the GLM801602's strength. While it cannot match the self-propelled MO48L4422's 70-minute combined figure or its hill-friendliness, as a pure power-and-runtime value in a push mower, the 80V is the standout, edging the 60V model on both fronts.
Where It Falls Short
The functional gaps are modest. It offers 3-in-1 rather than 4-in-1 cutting, so it lacks the dedicated leaf-pickup mode of the Greenworks 60V push, and it is push-only, so slopes are more work than with the self-propelled MO48L4422. It also feels heavier in use than the lighter 60V model.
The other caveat is model vintage: the GLM801602 is the older 80V push, and Greenworks' current 80V push SKUs cost meaningfully more for similar performance. That makes the GLM801602 a value find rather than the newest model, so stock can be more variable. For power per dollar, though, it remains a strong choice.
How It Compares to Alternatives
Against the Greenworks 60V 21-inch push, the 80V offers more voltage headroom and longer single-battery runtime at a similar price, though it drops the leaf mode. Against the EGO LM2114, it competes on power and price but lacks the EGO's premium Gator blade and far larger battery ecosystem.
It is push-only, so hill owners should choose the self-propelled Greenworks MO48L4422 instead. And the corded Sun Joe MJ403E is far cheaper but tethered and much less powerful. For buyers who want maximum cordless push power for the money, the 80V is the value-power pick.
Who It's Best For
The Greenworks 80V 21-inch push mower is for value-focused buyers who want the most cordless power-per-dollar in a push mower for flat-to-moderate lots up to a half acre. If raw cutting power and long single-battery runtime at a low price are your priorities, and you do not need self-propulsion, the GLM801602 delivers.
It is the wrong pick for hilly lots, where the self-propelled Greenworks MO48L4422 wins, for buyers who want the cleanest cut and biggest ecosystem (the EGO LM2114), and for those who want a dedicated leaf mode (the Greenworks 60V push). As a power-value push mower, though, it is a smart buy.
Strengths
- +80V brushless motor is the highest-voltage push mower here
- +Up to 60 minutes of runtime on the included 4.0Ah battery
- +Strong value, typically around $398 with battery and charger
- +21-inch steel deck with one-touch start and single-lever height adjustment
- +Includes battery, rapid charger, and grass bag in the kit
Watch-outs
- −3-in-1 functionality (no dedicated leaf mode like the 60V)
- −Push-only; no self-propulsion at this price
- −Heavier feel than the 60V push at around 60 lb
- −Older GLM801602 model; newer 80V SKUs cost considerably more
How it compares
The highest-voltage push mower here, with more headroom than the Greenworks 60V 21-inch push and runtime that rivals it, at a similar low price. It is push-only like the EGO LM2114 (which has the premium Gator blade and ecosystem edge), and for self-propulsion the Greenworks MO48L4422 is the pick. Far more capable than the corded Sun Joe MJ403E.
