Specs, pricing and buying notes taken from the manufacturer so you can compare this against whatever else you are looking at. I have not had this one in my hands. When it goes through real use it gets rewritten as a full review, with a rating and my own photos.

What Stands Out

  • Ships as a kit with a 56V 7.5Ah ARC Lithium battery and a Rapid Charger, so it runs the day it arrives
  • Select Cut multi-blade system swaps the lower blade between mulching, high lift bagging and extended runtime
  • 3-in-1 deck handles mulching, bagging into a two-bushel bag, or side discharge
  • Touch Drive self-propel with a variable speed dial from 0.9 to 3.1 MPH, so the pace matches your walk
  • Eight cutting heights from 1 in to 4 in with one-handed adjustment, plus LED headlights and a handle that folds for storage
  • The same 56V ARC Lithium battery runs the rest of the EGO line, including the blower and the multi-head power head

What To Check

  • Battery and charger compatibility is the thing to check first: this is the kit version, so if you already own EGO 56V batteries you are paying for one more plus a charger you may not need
  • Up to 60 minutes of run time is the ceiling, not the promise, and tall wet grass on the bagging blade pulls it down
  • Swapping lower blades is a real task with tools, not a switch you flip mid-mow
  • A 21 inch deck is a suburban lot tool; an acre and up is a different machine

The LM2135SP is EGO's 21 inch self-propelled mower, and it is the tool most people start a cordless yard with. It cuts on 56V ARC Lithium power, drives itself at a pace you set with a dial, and folds down flat enough to stand against a garage wall.

The part that matters more than the deck size is the battery. This listing is the kit, which means a 56V 7.5Ah battery and a Rapid Charger come in the box. That same battery and charger then run the LB6504 blower, the PH1420 power head and every other 56V EGO tool. Buy the kit once, then buy bare tools after that.

The Numbers That Matter

21 inch cut, 8 heights from 1 in to 4 in. The height range is what lets you run Bermuda short in summer and raise the deck for St. Augustine or a drought stretch. One-handed adjustment means you actually change it instead of leaving it wherever it sat last year.

Three lower blades. Select Cut means the lower blade comes off and a different one goes on: mulching, high lift for bagging, or extended runtime when you want minutes more than a manicured finish. Most decks make you pick one behavior and live with it.

Up to 60 minutes on the included 7.5Ah battery. That is the manufacturer's ceiling on an average yard. Thick, wet, or tall grass on the bagging blade cuts into it, which is the argument for a spare 56V 5.0Ah battery on the shelf.

0.9 to 3.1 MPH self-propel. The dial is the difference between a mower that drags you and one that walks with you. A slow setting is what you want around beds and a fence line.

SpecWhat it decides
21 in cut, 8 heights (1 to 4 in)How many passes a suburban lot takes and how short you can go
Select Cut, three lower bladesMulch, bag, or stretch the runtime
7.5Ah battery and Rapid Charger in the kitWhether you need to buy anything else to mow
56V ARC Lithium platformWhether one battery runs the blower and trimmer too
0.9 to 3.1 MPH Touch DriveWhether the pace matches your walk

Who It Is For

The dad on a quarter acre in a neighborhood with close houses, who is tired of gas cans, pull cords and spring carburetor work. If you are building the whole yard on one battery system, pair it with the 650 CFM blower kit for cleanup and the PH1420 power head with the string trimmer and edger attachments for the borders. For the hand work the mower cannot reach, the Fiskars bypass pruners and a Flexzilla hose round out the same Saturday.

The Short Version

This is the anchor of a cordless yard: a 21 inch self-propelled deck that comes with the battery and charger that then run every other 56V EGO tool you add. If you already have EGO batteries on the shelf, price the bare tool instead of the kit before you buy.
