EGO Power+ LM2135SP 21-Inch Select Cut Self-Propelled Mower Review
The EGO Power+ LM2135SP is a 21 inch cordless self propelled mower built around EGO's 56 volt ARC Lithium battery platform, and it sits near the top of the brand's walk behind lineup. This review covers the Select Cut model specifically, including its interchangeable blade system, variable speed drive, and the practical tradeoffs owners report after a full season of cutting.
Quick answer
It is right for homeowners with roughly a quarter to half acre who want gas level cutting power and self propulsion without fuel, oil changes, or pull starts, and who are willing to pay a premium and commit to the EGO battery platform.

EGO Power+ LM2135SP 21-Inch Select Cut Self-Propelled Mower
ReviewedPros
- Select Cut system accepts multiple blade types so you can swap between fine mulching and high lift bagging without tools
- Variable speed rear wheel drive lets you match pace to thick grass instead of fighting a fixed speed transmission
- Part of the EGO 56V platform, so the same batteries run trimmers, blowers, and chainsaws if you already own them
Cons
- Battery and charger are typically sold separately from the bare tool, which pushes the real out the door cost well above the sticker price
- It is heavy for a push mower, and the weight plus the drive system makes it less nimble around tight landscaping than a basic push unit
The LM2135SP pairs a 21 inch deck with EGO's Select Cut blade system and a variable speed rear wheel drive transmission. It is designed to deliver gas comparable cut quality with none of the fuel and maintenance chores. Build quality is aimed at regular residential use rather than light occasional trimming.
Real-World Notes
Owner feedback themes center on two things: cut quality and runtime. Most users report that mulching performance is strong once the right Select Cut blade is installed, and that the self propel system handles slopes without much effort. Runtime depends heavily on which battery you buy and how tall or wet the grass is, with thicker spring growth draining packs noticeably faster than light summer cuts. A recurring complaint is the weight when maneuvering around obstacles, and several owners note that the mower is quieter than gas but not silent.

Who Should Consider Something Else
Skip this if you have a very small lawn where a basic push mower is enough, if you are not willing to buy into the EGO 56V battery ecosystem, or if your budget is tight and you want a complete mower plus battery for a lower total price.
FAQs
Does the LM2135SP come with a battery and charger?
It is commonly sold as a bare tool, so confirm the listing before buying. Many retailers offer kits that bundle a battery and charger, and those kits cost more than the tool alone.
How large a lawn can it handle on one charge?
That depends on the battery capacity and grass conditions. With a larger EGO pack and normal growth, most owners cover a typical suburban lot, while thick wet grass shortens runtime significantly.
Is it really self propelled?
Yes. It uses a variable speed rear wheel drive system, so you set the pace with a lever rather than pushing the mower yourself.
What is the Select Cut system?
It is EGO's interchangeable blade design. You can swap between different blade types for mulching, bagging, or a combination, which changes how the clippings are handled.
Does it fold for storage?
Yes, the handle folds and the mower can be stored vertically in many setups, which helps in a crowded garage.
Our verdict
The EGO Power+ LM2135SP is a strong pick for anyone already on the EGO 56V platform or ready to commit to it, thanks to genuine gas comparable cutting and a flexible blade system. The main catches are the real world cost once you add a battery and the heft of the machine itself. If those tradeoffs fit your lawn and budget, it is one of the better cordless self propelled options in its class.
