Product Overview

The EGO Power+ LM2135SP Self-Propelled Cordless Lawn Mower is a cordless electric mower built around EGO’s 56V battery platform. It includes a 7.5Ah ARC Lithium battery and a rapid charger, which is a major value point because those accessories can be expensive when purchased separately. The mower uses a Select Cut multi-blade system intended to improve cutting quality over standard single-blade designs, and the Touch Drive self-propel system puts speed control directly under the user’s hand for easier maneuvering.

For homeowners who want a cleaner alternative to gas mowers but don’t want to compromise on performance, this mower aims to deliver a near gas-like experience with less maintenance and a more user-friendly operating style.

Pros & Cons

✅ Pros

  • Excellent cutting performance — the Select Cut multi-blade system improves lift, reduces clumping, and delivers a polished finish even in thick or mixed grass.
  • Touch Drive self-propulsion reduces fatigue — variable speed control (0.9–3.1 MPH) under your grip makes slopes and large yards far less demanding.
  • Strong runtime — up to 60 minutes on the included 56V 7.5Ah battery covers most small-to-medium yards on one charge.
  • Battery and rapid charger included — significant bundled value versus buying them separately.
  • Near-zero maintenance — no gas, no oil changes, no carburetor issues, and push-button starting every time.
  • 7 cutting height positions (1.5″–4″) plus 3-in-1 mulching, bagging, and side discharge for full seasonal flexibility.

❌ Cons

  • Premium price — at $749, it costs significantly more than most cordless competitors.
  • Real-world runtime varies — thick grass, slopes, and high self-propel speeds can cut the advertised 60 minutes noticeably shorter.
  • Heavier than basic cordless models — the self-propel helps, but lifting or transporting it takes some effort.
  • Single battery limits very large yards — users with oversized lots may want a second battery to avoid mid-mow charging breaks.

Detailed Review

1. Excellent cutting performance with the Select Cut system

The biggest selling point of the EGO Power+ LM2135SP is its Select Cut multi-blade setup. This is one of those features that can make a real difference in the final look of the lawn. Instead of simply chopping grass, the system is designed to improve lift, reduce clumping, and deliver a cleaner cut across different grass conditions.

For users who care about lawn appearance, this is especially valuable. If your yard tends to have thicker patches, slightly overgrown areas, or mixed grass types, the mower’s cutting system can help produce a more polished finish than many basic cordless mowers.

2. Self-propelled design reduces fatigue

The Touch Drive self-propel system is a major benefit for anyone mowing a larger yard or dealing with slopes, inclines, or uneven ground. Rather than pushing the mower’s full weight, you can control forward speed with the touch interface, which makes mowing less physically demanding.

This is the kind of feature that pays off immediately in comfort. For solo users, that matters a lot: less fatigue means faster mowing sessions, better consistency, and less temptation to skip maintenance because the job feels too exhausting.

3. Strong battery runtime for a cordless mower

The included 56V 7.5Ah battery provides up to 60 minutes of runtime, which is impressive for a self-propelled cordless model. In real-world use, runtime will vary based on grass height, terrain, blade load, and whether you run self-propel at higher speeds, but the advertised runtime is enough for many small-to-medium yards and some larger yards if managed efficiently.

For a single homeowner, the math is attractive: fewer interruptions, no fuel runs, and no cord management. The included rapid charger also helps reduce downtime between sessions.

4. Premium convenience and low maintenance

Like most cordless electric mowers, the EGO Power+ LM2135SP eliminates common gas mower headaches. There’s no gas to store, no oil changes, no carburetor issues, and no pull-start frustration. The push-button start is particularly useful for users who want quick, reliable starts every time, and the LED headlights extend usable mowing hours into early morning or dusk.

This simplicity is a major advantage for busy people who value convenience and consistency. It also makes the mower a strong fit for users who want equipment that is ready when they are, without pre-season tune-ups or messy maintenance routines.

5. Adjustable speed and cutting height improve usability

The adjustable self-propel speed range from 0.9 MPH to 3.1 MPH gives users more control than many fixed-speed models. That flexibility makes a difference if you alternate between flat areas, slopes, and tight corners. It also makes the mower more approachable for users with different walking paces.

Combined with 7 cutting height positions from 1.5 to 4 inches and 3-in-1 functionality (mulching, bagging, side discharge), the mower adapts well to seasonal changes — shorter, cleaner cuts in spring and taller, drought-protecting heights in summer.

Who Should Buy the EGO Power+ LM2135SP?

  • Buy it if: you have a medium-to-large yard (up to roughly half an acre), deal with slopes or uneven terrain, and want gas-like cutting quality without gas maintenance.
  • Skip it if: you’re on a tight budget, your yard is small enough for a basic push mower, or you need more than 60 minutes of runtime without investing in a spare battery.

FAQ

How long does the battery last on the EGO Power+ LM2135SP?

The included 56V 7.5Ah battery delivers up to 60 minutes of runtime on a single charge. Real-world runtime varies with grass height, terrain, and self-propel speed — expect closer to 40–50 minutes in thick or wet grass, and up to the full hour in light conditions on a medium-height setting.

Is the EGO LM2135SP powerful enough to replace a gas mower?

For most homeowners, yes. The high-efficiency brushless motor and Select Cut dual-blade system deliver cutting performance comparable to a gas walk-behind mower, including in thicker grass. The main trade-off is runtime management on very large properties, where a second battery may be needed.

What size yard is the LM2135SP best suited for?

With up to 60 minutes of runtime, it comfortably handles yards up to about half an acre on a single charge. Larger yards are still workable if you plan around charging breaks or add a second EGO 56V battery, which is compatible across EGO’s entire outdoor tool lineup.

Does the Touch Drive self-propel system work on hills?

Yes. The variable-speed self-propel drive takes most of the mower’s weight off your arms, which makes slopes and inclines significantly easier. You can dial the speed down for climbing and tight corners or up to 3.1 MPH for open, flat stretches.

Can the EGO LM2135SP mulch, bag, and side discharge?

Yes, it’s a full 3-in-1 mower. You can switch between mulching, rear bagging, and side discharge depending on the season and lawn conditions. Mulching works best on dry grass cut at regular intervals, while bagging is the better choice for overgrown lawns or fall leaf cleanup.

Is the $749 price worth it?

If you value cutting quality, self-propulsion, and low maintenance, the bundled battery and rapid charger justify the premium for most medium-to-large-yard owners. Over a few seasons, you also save on gas, oil, spark plugs, and tune-ups, which narrows the price gap versus comparable gas self-propelled models.
