Greenworks LM1624 16-inch 40V brushless push mower kit review

A compact 40V kit, not a powered-drive mower

The Greenworks LM1624 is a 16-inch, 40V brushless push kit, retail SKU 2540802; its linked manual identifies internal model LMF417. The carton lists one 4.0Ah battery, a charger, catcher, mower and manual. It has no powered travel drive. Its narrow cut can help on divided lawns, but deck width is not full assembled width; check gates against the physical mower before relying on the 16-inch figure.

Choose it for a simple two-route routine

Greenworks describes a 2-in-1 system for mulching and rear bagging. Its matching LMF417 manual shows the grass catcher and mulch plug as separate pieces and explains how to swap them at the rear opening. That gives the owner two distinct ways to manage clippings: collect them in the supplied bag, or fit the plug for a mulching pass. There is no documented side-discharge route for this configuration, so a homeowner who routinely needs a side chute should choose another mower rather than assume a nearby Greenworks model's attachment applies here. The exact kit page lists the catcher; if having a mulch plug in the carton is essential, verify that part against the actual box rather than treating a general feature statement as an itemized inclusion.

The five-height single lever spans 1¼ to 3⅜ inches in both the exact listing's feature text and the matching manual's technical table. The manual also says to raise the setting for new or thick grass and not to mow damp or wet turf. That range is useful for someone who prefers a relatively low cut and wants room to raise the blade as conditions change, but it is not a substitute for matching the height to the grass species and season. The manual's 3,500-rpm value is a no-load speed, not a measured cutting result.

One battery, two different kinds of claims

The kit's single 4.0Ah battery and charger keep the first purchase self-contained. Greenworks claims up to 45 minutes of runtime and a 120-minute recharge with the included charger. Those figures are manufacturer ceilings; they do not promise a full 45 minutes while bagging tall or damp grass, nor do they predict the area a particular property will take. The page's acreage text is internally inconsistent: a feature/specification block says one-quarter acre while the hero and extended product specification say up to one-third acre. I do not treat either number as a reliable hard capacity threshold. If finishing a measured lawn on one charge is essential, use the maker's claims only as a starting point and allow for grass height, turns, slope and clipping load.

Greenworks promotes a shared 40V tool line, but voltage branding alone does not establish that every pack physically fits this mower. The reviewed kit includes one 4.0Ah pack. If two packs, a spare onboard or self-propelled travel is essential, this configuration does not meet that need.

Transport weight and storage need a closer look

The exact product page lists “product weight” as 40.7 pounds without explaining the weighing basis; the LMF417 manual lists the machine at 29 pounds without the battery. Those statements describe different bases and are not a clean ready-to-mow weight comparison. The manual's bare-mower figure may help when thinking about lifting the tool body, but it should not be quoted as the weight of the complete kit. If stairs, a vehicle lift or a wall hook are part of the decision, handle the assembled mower or request a clarified packaged and operating weight first.

The handle folds, but the advertised “up to 70% less” claim is not a measured footprint for your garage; the manual also warns against pinching the cables. For shutdown or cleanup, wait for the blade to stop, remove the battery, clear debris and do not hose the deck. The manual says not to mow wet grass or slopes above 15 degrees and not to mow up and down a slope. Only cross a manageable slope if footing is stable.

There is an open-box package as well

Greenworks also lists Open Box SKU 2540802-OB with the same LMF417 model code and 4.0Ah kit. The page describes a new, unused mower moved to alternate packaging because its original box was damaged, then inspected and tested. But its warranty language conflicts: the specifications state 90 days for tool and battery, while Warranty + Service says three years for each. Ask Greenworks which term governs SKU 2540802-OB; do not assume the standard kit's protection applies.

Who should shortlist the LM1624?

Choose this 16-inch kit when operator-powered travel, a 40V battery, a modest cutting path and documented mulch/bag operation line up with the lawn. Its relatively narrow cut and foldable handle are practical for small divided areas, but the mower's full dimensions and actual runtime matter more than a deck label. It is not the fit for side discharge, self-propulsion, or a confidently established one-third-acre workload from the available product text.

Compare the 14-inch LM1404 when a narrower path matters. Both are 40V push kits with mulch/bag operation, but the LM1404's linked manual names a different SKU and its height figures conflict. The LM1404 assessment details that uncertainty. LM1624 has the clearer manual bridge, but its acreage and full operating weight remain uncertain. For either, follow the manual matching the mower label and clear objects before mowing.
