Quick verdict
The EGO cuts finer, runs longer on its kit pack and belongs to the broadest battery yard platform; the Greenworks costs less and does a normal lawn well. For a quarter acre on a budget, the Greenworks. For anything bigger, or for a yard that will fill with EGO tools, the LM2156SP.

Where these two differ
Both are 21-inch steel-deck self-propelled battery mowers. The EGO LM2156SP has the Select Cut stacked blade system, a Touch Drive handle and a 10 Ah pack in the kit, at a premium price. The Greenworks 80V 21-inch has a single blade, rear-wheel drive and a 4 or 5 Ah pack in most kits, at a lower price. The EGO cuts finer and runs longer; the Greenworks does a normal lawn for less.
This comparison is based on the published specifications and manuals for both mowers and on recurring owner feedback. We have not run either mower ourselves.
| Specification | LM2156SP | Greenworks 80V 21 |
|---|---|---|
| Deck | 21 inch steel | 21 inch steel |
| Blades | Select Cut stacked | Single |
| Battery in kit | 10 Ah | 4 or 5 Ah |
| Runtime claim | Up to 90 min | About 60 min |
| Drive | Touch Drive | Rear wheel, variable |
| Price | Higher | Lower |
Cut quality
The EGO Select Cut chops clippings twice and leaves mulch that disappears; bagging is clean with the high-lift blade. The Greenworks single blade cuts evenly and mulches acceptably in dry grass; in thick spring growth it leaves visible clippings and the bag fills faster.
Runtime and batteries
A 10 Ah EGO pack covers a half acre with reserve. A 4 Ah Greenworks pack covers a quarter acre; a 5 Ah pack a little more. The Greenworks kits are cheaper partly because the pack is smaller, and a second pack closes the gap at a cost.
Drive and handling
Touch Drive on the EGO moves the mower when the handle is pressed and stops it when released, with variable speed. The Greenworks rear-wheel drive uses a bail and a speed lever and climbs slopes well. Both fold for storage; the Greenworks is lighter.
Platform
EGO 56V runs blowers, trimmers, chainsaws, snow blowers and a riding mower. Greenworks 80V runs blowers, trimmers, chainsaws and a snow blower. Both are real yard systems; EGO is the broader and more widely sold.
Yard jobs this decides
A quarter acre on a budget: the Greenworks. A half acre, a thick lawn or a yard that will fill with EGO tools: the LM2156SP. Slopes are a draw; both drive well.
Warranty and support
On the EGO Power+, EGO covers tools with a five-year limited warranty and packs with three years. On the Greenworks 80V, Greenworks covers 80V tools with four years and packs with two. Both makers run service networks in the US and both honor the warranty only with proof of purchase, so keep the receipt with the manual. Registration takes a few minutes online and is worth doing the day the tool arrives.
Common owner complaints
LM2156SP owners mention price and deck rust at the lip. Greenworks owners mention runtime on the kit pack and plastic trim. Both are reliable.
Which one should you buy
Buy the LM2156SP for cut quality, runtime and the broadest platform. Buy the Greenworks 80V for a normal lawn at a lower price.
