Verdict: Choose a 56v lawn mower if you want the wider decks and longer stated runtimes from the EGO examples. Choose a 40v lawn mower if you want a lighter push mower, with the Greenworks example including a battery and charger, or a bare tool that runs on Dewalt batteries from the Houselife example.
When spring growth turns the yard shaggy and the weekend mow becomes a regular chore, the battery platform under the deck matters as much as the deck itself. The 56v vs 40v lawn mower question comes down to deck width, stated runtime, weight and what comes in the box. This comparison covers the differences, then examples from the listings reviewed on both sides.

Figures are manufacturer stated for the four example models, collected 30 October 2026.
Voltage and runtime
Voltage is the headline difference, but runtime is where the listings separate. The EGO LM3004SP-2 example runs on two 56V 6.0Ah batteries with up to 75 minutes of runtime on a single charge, and the EGO LM2244SP-2 example runs on two 56V 6.0Ah batteries with up to 90 minutes of runtime. On the 40v side, the Greenworks example states up to 45 minutes of runtime on a fully charged 4.0Ah battery, while the Houselife example states no runtime at all, so the runtime comparison rests on the three examples that state one. Higher voltage alone does not set runtime; compare battery amp hours and stated runtime instead.
The battery systems differ too. The EGO LM2244SP-2 example is compatible with all EGO 56V ARC Lithium batteries, and the Greenworks example works with 75+ Greenworks 40V tools. The Houselife example needs two Dewalt 20V MAX batteries to provide 40V power and ships as a tool only.
Deck width and cutting heights
Deck width decides how much ground each pass covers. The EGO LM3004SP-2 example cuts a 30-inch path with a Super Composite deck and dual motors powering two independent cutting blades, while the EGO LM2244SP-2 example cuts a 22-inch path with a Super Composite deck and a multi-blade cutting system with interchangeable lower blades. Both 40v examples cut a 14-inch path. The Greenworks example has a steel deck, while the Houselife listing states a manganese steel blade and no deck material. A wider deck covers open ground in fewer passes, while a narrower deck suits smaller yards and tight spots around beds and trees.
Cutting height adjustment differs across the four. The EGO LM3004SP-2 example offers Nine cutting height positions, adjustable from 1 to 5 inches with levers in the front and rear. The Greenworks example offers a single lever 5-position height adjustment from 1-1/4 inches to 3-3/8 inches, and the Houselife example offers a single-lever 6-position height adjustment from 0.98 inches to 3 inches. The EGO LM2244SP-2 example states no cutting height positions.
Weight and handling
Weight is where the 40v side makes its case. The Houselife example lists 22 lbs and describes an ultralight design for maneuvering around flower beds and trees, and the Greenworks example lists 36.38 pounds in the spec table. The EGO examples list far higher weights in their spec tables, 166.0 pounds for the LM3004SP-2 example and 120.0 pounds for the LM2244SP-2 example, but both are self-propelled with Touch Drive technology. The 40v examples have no self-propelled drive stated: the Greenworks is a push mower and the Houselife is a walk-behind mower, so the handling trade is plain: the 56v examples carry more weight with drive assistance, while the 40v examples are lighter to push by hand.

The Acre Score explained
The Acre Score weighs five factors: performance (voltage, deck, runtime and drive), build quality (deck and handle), value (batteries, charger and extra tools in the box), safety (ratings or controls the listing states) and warranty (years and coverage). A factor the listing does not state scores zero, which is why all four examples score zero for safety.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EGO LM3004SP-2 | 9.6 | 32 | 21 | 20 | 0 | 3 |
| EGO LM2244SP-2 | 9.5 | 30 | 21 | 20 | 0 | 3 |
| Greenworks 40V 14in | 9.3 | 24 | 18 | 19 | 0 | 2 |
| Houselife 40V 14in | 9.2 | 23 | 16 | 15 | 0 | 1 |
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.
For larger, rougher ground beyond these walk-behind examples, see our brush and field mowers guides.
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.
FAQ: mowing large lots
Does higher voltage mean longer runtime?
Not on these listings alone. The EGO 56v examples state up to 75 minutes and up to 90 minutes of runtime, the Greenworks 40v example states up to 45 minutes, and the Houselife 40v example states no runtime, so compare battery amp hours and stated runtime, not voltage alone.
Which mower is lightest?
Among the four examples, all of which state a weight, the Houselife example lists 22 lbs, the Greenworks example lists 36.38 pounds, the EGO LM2244SP-2 example lists 120.0 pounds, and the EGO LM3004SP-2 example lists 166.0 pounds, so the Houselife example is the lightest here.
Do the 40v mowers include batteries?
One does and one does not. The Greenworks example includes a 4.0Ah battery and charger, while the Houselife example is a tool only that needs two Dewalt 20V MAX batteries, with no battery or charger in the box.
What deck width suits a smaller yard?
The 14-inch examples suit smaller yards and tight spots. The 22-inch and 30-inch examples cover open ground in fewer passes.
Can one battery serve other tools?
Yes for the Greenworks example, which works with 75+ Greenworks 40V tools, and for the EGO LM2244SP-2 example, which is compatible with all EGO 56V ARC Lithium batteries. The Houselife example runs on Dewalt 20V MAX batteries.
