The EGO Power+ LM2102SP is a 21 inch cordless self propelled walk behind mower built around the brand's 56 volt ARC Lithium battery platform. It sits in the middle of EGO's lineup, pairing a steel deck and variable speed drive with the convenience of push button starting and no gas, oil, or pull cords.

It is right for homeowners with small to medium suburban lawns who already own or plan to buy into the EGO 56V battery platform and want gas free mowing without giving up self propulsion.

EGO Power+ LM2102SP 21-Inch Self-Propelled Mower
ReviewedPros
- Self propulsion with variable speed makes sloped and larger yards far less tiring than a push mower
- Part of the EGO 56V platform, so one battery family can run trimmers, blowers, and chainsaws
- Folding handle and vertical storage plus no gas or oil means low maintenance and easy garage storage
Cons
- Battery runtime depends heavily on grass conditions and which Ah pack you use, so a single small battery may not finish a large yard
- It costs more up front than a comparable gas mower, and replacement EGO batteries are a real added expense
This is a 21 inch steel deck cordless mower with rear wheel variable speed self propulsion and a 56V EGO ARC Lithium battery system. It is designed for homeowners who want gas like cutting performance without fuel, fumes, or pull starts. The kit version ships with a battery and charger so it works out of the box.
Real-World Notes
Owner feedback themes center on easy starting, quieter operation than gas, and the self propel system doing the hard work on hills. Common complaints involve runtime on thicker or wet grass, the need for a second or larger battery on bigger lots, and the higher entry price once you factor in batteries. Most owners report the cut quality is comparable to a mid range gas mower when the blade is kept sharp and the deck is not overloaded.

Who Should Consider Something Else
Skip this if you have a very large lawn that would need multiple batteries per mow, if you are on a tight budget and a gas mower fits your needs, or if you are already invested in a different battery platform and do not want to start a second one.
FAQs
Does the EGO LM2102SP come with a battery and charger?
The LM2102SP is commonly sold as a kit that includes an EGO 56V ARC Lithium battery and a charger, though battery capacity varies by listing, so check the specific bundle before buying.
How long does the battery last on this mower?
Runtime depends on battery amp hours, grass thickness, and whether self propel is engaged. EGO rates runtime per battery, and owners typically report enough for a typical suburban front and back yard with a mid size pack, less in tall or wet grass.
Is the EGO LM2102SP self propelled?
Yes. It uses a variable speed rear wheel drive self propel system, so you set the pace rather than pushing the mower yourself.
What size lawn is this mower good for?
It suits small to medium residential lawns, roughly up to about a quarter acre per charge depending on battery size and conditions. Larger properties usually need a spare battery or a bigger platform.
Does it mulch and bag?
Yes. It supports mulching, bagging, and side discharge, so you can match the setup to your lawn and season.
Our verdict
The EGO Power+ LM2102SP is a strong cordless self propelled mower for small to medium yards, especially if you are already on the EGO 56V platform. Its main trade offs are battery runtime on tough grass and a higher up front cost than gas. If those do not scare you, it is one of the better gas free options in its class.
