A best battery powered string mower pairs those jobs in a single battery kit, so a shared set of batteries covers mowing, trimming and cleanup. The picks below compare battery mowers and combos by deck width, battery, runtime and warranty, and mark what each listing does not state.

The bullets say 12 in for the cutting width, but the title and spec table say 13 in, so the listing disagrees with itself on width. Item weight is 25.4 lb and no warranty term is stated.
Pros
- Trimmer converts to an edger with a 7-position pivoting head
- Up to 22 minutes of mower runtime on a 24V Max battery

Read the full review
The kom-lw is a 40V push mower with a 16 in deck, a brushless motor up to 3400 RPM, 2-in-1 mulching and bagging with a 10.6 gallon bag, and 5 cutting positions from 1.37 to 2.95 in. The listing states a dual-action safety switch that needs the side safety button plus the start lever, 2 batteries and 2 chargers, and up to 10 minutes of runtime. The title also calls it a small push lawn trimmer, but the listing describes a mower, so read it as a mower, not a trimmer. No warranty term is stated.

- 2-in-1 mulching and bagging with a 10.6 gallon bag
- Brushless motor up to 3400 RPM with a 16 in deck

Cons
- Up to 10 minutes of runtime only
- No warranty term is stated

Buying guide: best battery powered string mower
Mower, trimmer and blower in one kit
The Greenworks kits bundle a mower, a trimmer and a blower on one battery platform, while the LawnMaster kit bundles a mower and a trimmer, and the KOMASTY listing is a mower alone. A bundle suits a yard that needs edges and cleanup as well as mowing.
Battery and runtime
The Greenworks kits run on 48V with two 24V batteries, the KOMASTY mower runs on 40V and the LawnMaster combo runs on 24V Max. Battery counts differ: 3 batteries in the Greenworks combo, 2 batteries in the other picks. Runtime claims differ more: up to 30 minutes for the Greenworks combo per its bullets, up to 22 minutes for the LawnMaster combo and up to 10 minutes for the KOMASTY mower. The Greenworks kit states no runtime in minutes. Read runtime next to deck width.
Cutting width and height adjustment
Decks run from 13 in on the LawnMaster combo to 20 in on the Greenworks kits, with the KOMASTY mower at 16 in. Height adjustment runs from 5 positions on the LawnMaster and KOMASTY mowers to 7 positions on the Greenworks kits. Height ranges: 1 to 2.55 in on the LawnMaster, 1.37 to 2.95 in on the KOMASTY and 1.375 to 4 in on the Greenworks combo.
Wheels, weight and storage
Weights run from 25.4 lb on the LawnMaster combo to 71 lb on the Greenworks kit, with the Greenworks combo at 48 lb. The KOMASTY listing does not state a weight. For storage, the Greenworks combo lists vertical storage with foldable handles.
Warranty
Both Greenworks kits state 3-year warranties, one for tool and battery and one limited for tool and battery. The LawnMaster and KOMASTY listings state no warranty term, so those picks get no warranty points.
Slopes
None of the listings states a slope limit. Keep to gentle ground, keep children and pets out of the yard while mowing, wear eye and hearing protection for trimming work, and clear debris before cutting.
Walk the area first and clear stones, sticks, wire and toys. Wear eye and hearing protection, long pants and sturdy closed footwear, mow across slopes with a walk-behind (not up and down), and never pull a running mower toward you. Keep kids and pets well away. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Flat lawns with edges and paths: the Greenworks and LawnMaster combos pair a mower with a trimmer for edges.
- Tight storage: the Greenworks combo lists vertical storage with foldable handles.
- Weight: the LawnMaster combo lists 25.4 lb, against 48 lb and 71 lb for the Greenworks kits.

- Thick or wet grass: the Greenworks combo lists a turbo mode for thick and wet grass.
The Acre Score explained
The Acre Score weighs performance (cutting width, battery, what it can cut), build quality (deck, wheels, drive), value (specs for the money), safety (operator controls such as a safety switch or thermal management) and warranty (years and coverage). A factor the listing does not state scores zero.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Greenworks 1341602-VK | 9.7 | 30 | 21 | 21 | 5 | 4 |
| Greenworks CK24L4242 | 9.5 | 29 | 21 | 20 | 0 | 4 |
| LawnMaster 20VMWGT | 9.4 | 27 | 19 | 20 | 0 | 0 |
| KOMASTY 40V Mower | 9.3 | 22 | 19 | 16 | 4 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
