Greenworks Mower

The Verdict

If you’re staring at a mid-sized lawn and want to ditch gas cans and extension cords, the Greenworks cordless mower looks like the obvious answer. But with a 3.6-star average across 180 ratings, the reality is more complicated. Here’s what I found digging through real owner experiences and spec sheets.

What’s actually in the box
You get the mower deck, a battery (usually a 40V or 80V depending on the bundle), a charger, a mulching plug, and a side-discharge chute. No assembly beyond unfolding the handle — that takes about five minutes. The unit weighs roughly 35-40 pounds, which is noticeably lighter than most gas mowers. As shown in the product image, the design is compact and folds for vertical storage, which matters if your garage is tight.

Performance that depends on your lawn
On flat, well-maintained grass under six inches tall, this mower cuts cleanly. The brushless motor (on most models) delivers enough torque to handle damp grass without bogging down dramatically. But here’s the catch: the battery. On a typical 40V 4Ah pack, expect 25-35 minutes of actual cutting. That covers about a third of an acre before you’re swapping batteries. One reviewer put it bluntly: “Took two full charges to finish my 0.4-acre lot. The mower works, but the battery readout is optimistic.”

The 20-inch deck is narrower than the standard 21-inch gas mower. Doesn’t sound like much, but that’s 5% more passes per row. On a quarter-acre, that’s an extra 10-15 minutes of pushing.

What owners consistently praise
The quiet operation is a genuine win — neighbors won’t hate you at 7 AM. The lightweight build gets frequent shoutouts, especially from older users. One verified purchase said: “I’m 68 and can push this with one hand on flat ground. My old Toro felt like a truck.” Starting is instant — no pull cord, no choke, no flooded carburetor. For anyone who’s spent a Saturday morning yanking a starter rope, that’s worth something.

Where it actually falls short
Beyond battery range, the deck has a known issue. The plastic housing flexes if you hit a bump or thick root, and several reviewers report the blade dips, scalping the lawn. One buyer noted: “Left a bald strip across my yard on the first pass. Had to slow down and go over it again.” The cutting height adjustment is a lever system — fine for flat lawns, but it doesn’t hold as firmly as a gas mower’s pin system, so it can drift mid-mow.

Also, don’t expect this to handle wet grass without clumping. The mulching function chokes on anything damp, and you’ll be clearing the underside more than you’d like.

Who should buy this — and who shouldn’t
Buy it if you have a small, flat yard (under 2,500 square feet), hate maintenance, and want a quiet, clean tool. It’s ideal for townhouse lawns or first-time homeowners who’ve never owned a mower. Skip it if you’ve got rolling terrain, a yard over a quarter acre, or you’re the type who mows every 10 days — this needs consistent, short grass to perform.

Three questions shoppers actually ask
Does the battery charge fast?
A full charge takes about 1-2 hours depending on the charger included. Plan accordingly — you can’t just top it off during a coffee break.

Can I use other Greenworks batteries?
Yes, within the same voltage family. A 40V mower takes any 40V Greenworks battery. That’s the brand’s ecosystem advantage — buy a second battery, and you can swap mid-mow.

Is it safe on slopes?
It’s fine on gentle grades, but the lightweight build means rear wheels can lose traction on anything steeper than about 15 degrees. On hills, it wants to slide sideways.

The verdict
This is a solid starter mower, not a workhorse. It earns 3.7 stars because it nails the basics — lightweight, quiet, zero maintenance — but stumbles on battery stamina and deck rigidity. For a small, flat lawn, it’s a genuinely good buy. For anything bigger, you’ll be frustrated.

Buy it if you have a small, level yard, want push-button starting, and don’t mind an extra battery purchase.
Skip it if your lawn is large, uneven, or you’re replacing a gas mower expecting equal power.

I’d rate it 3.7/5 — decent value for the right buyer, but not a universal recommendation.
