Black+decker 20-Inch Electric Lawn Mower Review: Pros, Cons & Who It’s For

Black+decker 20-inch electric lawn mower review: the listing at a glance

Who the MM2000 is for

• Small-lawn owners under 1 acre who want a simple electric mower with no battery to charge, replace or run flat mid-cut.
• Keepers who like options at the back of the mower: mulching, bagging and side discharge are all on one machine, so you can mulch leaves in fall and bag in spring.
• Anyone cutting close to fences and beds, where the EdgeMax deck design is meant to trim near the edge and save string-trimmer time.
• Buyers who read warranty terms: the 2-year limited warranty is stated plainly in the bullets and the spec table.

The pick in detail

Below is our card for the one model in this review, with the Acre Score it earned. A single-review card carries the full 4 pros, 4 cons and the who-it-is-for summary in one place.

What the MM2000 does well

3-in-1 cutting in one mower

The 20-inch deck handles mulching, bagging and side discharge, so one machine covers a season of different conditions. Mulch mode drops clippings back into the lawn, bag mode collects with the 13-gallon fabric bag, and side discharge throws clippings aside when the grass is too tall to mulch. The 13-amp motor is the maker’s claim for cutting through thick grass and overgrowth, stated as ample power rather than a measured figure.

Easy height changes

A single lever adjusts the cut across 7 settings from 1.5 to 4 inches. That range covers a low, tidy cut and a tall, drought-safe cut without touching each wheel, and the 4-inch top end gives you room to raise the deck in rough summer patches. Our mulching blade picks explain how blade choice pairs with the mulch mode.

Stated 2-year warranty

The listing states a 2-year limited manufacturer’s warranty in both the bullets and the spec table. Because the term is concrete, the MM2000 earns warranty points in our Acre Score. Keep the receipt and read the manual’s exclusions, but a stated term you can hold the maker to beats the silent listings at this end of the market.

No battery to manage

Corded electric means no charge time, no battery aging and no spare pack to buy. If you mow a small yard and an outlet is within reach, the MM2000 starts when you plug it in. The alloy steel deck and 8-inch wheels are the stated build basics; nothing fancy, but nothing battery-specific to wear out either.

Limitations to know before you buy

The “ultra light” claim does not match the weight

The title calls it an ultra light push mower, but the spec table lists 46.9 pounds. That is a real weight to push, not a featherweight, so expect a real push on thick grass and plan how you lift it into the shed. We trust the 46.9-pound figure over the marketing word in the title.

The spec table contradicts the title on deck size

The title and bullets say 20 inches, but the spec table lists a cutting width of 50.8 inches, which would make the deck wider than the mower is long at 34.9 inches. That is a spec-table error, not a different model. We trust the 20-inch figure from the title and bullets, and the mismatch is worth knowing because it shows the spec table was not carefully checked.

Corded means tethered

No listing figure states the cord length, and a corded mower is only as far-ranging as its extension cord. You need a proper outdoor-rated cord, you mow in a pattern that keeps the cord behind you, and large lawns turn into a cable-management chore. If you hate cords, our battery electric mower picks cut the tether entirely.

Manual push only

The listing describes a manual push mower with no self-propelled drive stated. On flat small lawns that is fine, but on slopes or thick spring growth you do the pushing. Rated acreage, blade speed and cord length are also not stated, so there is no official number for how far one outlet run will take you.

Who should skip the MM2000

• Owners who need a self-propelled drive for slopes or a big lawn; a battery or gas self-propelled model from our walk-behind push mower picks will do the pushing.
• Anyone whose mowing area sits far from an outlet, where a corded machine means a long extension cord and constant re-routing.
• Buyers who lift the mower over steps or into a truck bed regularly; 46.9 pounds is not ultra light, whatever the title says.
• Anyone who wants a battery platform shared across tools, since this mower is corded-only by design.

Alternatives

If the cord is the dealbreaker, our best battery electric lawn mowers cover cord-free options by deck size and battery system. If you want more power for thick or tall grass, see the best gas lawn mowers. For self-propelled help on bigger yards, the self-propelled mowers for 1 acre guide is the next read. Browse the category in walk-behind and robotic mowers.

Walk-behind safety basics: wear eye and hearing protection, clear rocks, branches and toys from the yard before you mow, and keep the cord behind you and out of the deck’s path. Never mow across a slope you cannot walk comfortably; a 46.9-pound mower slides faster than you do on wet grass.

FAQ: mowing large lots

Is the BLACK+DECKER MM2000 really ultra light?

The title says ultra light, but the spec table lists 46.9 pounds. That is a real weight to push, not a featherweight, so expect a real push on thick grass.

How wide is the MM2000’s cutting deck?

20 inches, per the title and bullets. The spec table’s 50.8-inch cutting width contradicts the rest of the listing and the mower’s 34.9-inch overall length, so we treat it as a spec-table error.

Does the MM2000 need a battery?

No. It is corded electric with a 13-amp motor. You plug it in and mow; there is no battery to charge, but you are limited by the extension cord’s reach, which the listing does not state.

What does the warranty cover?

The listing states a 2-year limited manufacturer’s warranty. Read the manual for exclusions; the term itself is stated in both the bullets and the spec table, which earns it warranty points in our Acre Score.

Can the MM2000 mulch, bag and discharge?

Yes. The 20-inch deck is 3-in-1: mulching, bagging with the 13-gallon fabric bag, and side discharge, per the bullets.
