Greenworks LM2118 21-inch 80V Gen 2 push mower kit review

The LM2118 is a push mower with an extra battery bay

Greenworks identifies the 80V, 21-inch Gen 2 kit as LM2118, SKU 2541202 and internal model LMB454. The exact package includes a brushless mower, one 4.0Ah 80V battery and a 4A rapid charger; the page also names a grass-catching bag and owner’s manual. It has a steel stamped deck, LED headlights, folding handles and a seven-position cutting-height range of 1⅜ to 4 inches. The linked 48-page manual cover prints LMB454, tying the operator instructions to the exact code more closely than a generic 80V search result would.

Auto-Switch is the feature that distinguishes this package from a simple single-port assumption: Greenworks’ exact page says there are two active battery ports, and the manual says the other battery can work when the first cannot. But this kit includes one battery. A second port is not a second pack. If you require two batteries to be supplied with the mower, LM2118 fails that requirement as packaged; if you already own a compatible Greenworks 80V battery, the second port may matter. Do not treat the two packs as a single fictional 8Ah battery or translate their capacities directly into runtime.

Travel control: resolve the page and manual conflict carefully

The exact listing calls LM2118 a push mower, and its model-code page describes the package as push. The LMB454 manual’s control overview shows a start button and start handle but no self-propel lever. However, the same manual’s generic slope guidance and technical table refer to self-propelled speed. That wording is inconsistent with the exact kit title and the controls actually diagrammed for LMB454. For matching and purchase decisions, treat SKU 2541202 as push-only, not a self-propelled mower. If the machine delivered to you has a different model code or a separate drive control, use its own identity and manual rather than assuming it is this configuration.

The manual documents mulch, rear bag and side-discharge arrangements. Its technical table also lists Turbo, and the operating instructions explain that Turbo raises no-load blade speed to 3,200 rpm from a 2,800-rpm default. Turbo is a speed setting, not a fourth physical clipping route or a leaf vacuum. The packing list includes the grass catcher and side-discharge chute; it does not separately list a mulch plug, although the manual explains how to fit one. If mulching is essential and the insert is not in your carton, resolve the correct part before your first cut. The page’s broad “4-in-1” marketing label should not be mistaken for four independent discharge configurations.

One included battery changes the runtime question

The product page claims up to 40 minutes and up to a half-acre with the included 4Ah pack, and says a battery recharges in about 60 minutes with the included charger. These are maker maximums, not a guarantee of finishing a yard. Grass height and density, the cut setting, bagging, temperature, terrain and Turbo use all affect the result. The manual explicitly says not to mow wet grass and directs the owner to mow across slopes rather than up or down, not on slopes greater than 15 degrees, and not where footing is uncertain.

For lifting and storage decisions, the manual specifies 60.6 pounds without the battery. Add the separately supplied pack when considering the complete operating weight; do not quote the bare-mower figure as the ready-to-mow mass. The product page lists a four-year limited tool and battery warranty. The page also lists a seven-position height adjustment and the manual agrees on the 1⅜-to-4-inch range. These published specifications are more useful than a general “2x torque” slogan, which is not a quantified torque comparison for this exact configuration.

Who should choose LM2118?

LM2118 suits a homeowner who prefers to push, wants a 21-inch steel-deck mower and values a one-pack 80V kit with an option to use a second battery in the Auto-Switch system. It can be a poor fit if powered travel is essential, if two packs must arrive in the box, or if the exact supplied mulch insert is a must-have and the package contents cannot be confirmed. Compare it with LM2108 by exact configuration: both are 21-inch push kits with one 4Ah pack, while LM2118’s documented dual active ports add an expansion route. The open-box LM2118S is a different, self-propelled package with a 4Ah and a 2Ah battery; its warranty text conflicts, so it should not be substituted silently. When gate width, included battery count, or the exact blade and clipping parts matter, match the retailer’s SKU 2541202 to the carton and its LMB454 manual before deciding.
