EGO Power+ LM2100 56V Cordless Mower Review

The EGO POWER+ LM2135SP 21” Self-Propelled Cordless Lawn Mower sits at the serious end of the battery-powered mower market, and it earns that position. I’ve been running it across roughly three acres of mixed terrain on my Litchfield County property for two full mowing seasons, and my assessment is straightforward: this is the machine that finally made me stop defending gas mowers to skeptical neighbors. Not because it’s perfect, but because the tradeoffs have shifted decisively in EGO’s favor. If you’re already invested in the EGO 56V platform, or considering building a battery-powered tool ecosystem, the LM2135SP deserves a direct look.

Quick Verdict

Buy it if you have a half-acre to an acre of maintained lawn and want a mower that handles real grass without babying. The 7.5Ah 56V battery delivers genuine runtime rather than marketing runtime, the self-propel system works on slopes that would exhaust most people pushing, and the multi-blade cutting system is noticeably better than the single-blade setup on the previous LM2100. Pass on it if you’re expecting to mow two-plus acres on a single charge without a backup battery, or if you need it ready in 20 minutes and haven’t budgeted for the rapid charger.

Currently priced around $699 for the kit (battery and rapid charger included) or approximately $449 for the tool-only version, at the time of writing. The 7.5Ah battery alone sells separately for around $249, so if you’re new to the platform, the kit is the better entry point by a significant margin.

Key Specs

The LM2135SP runs on EGO’s 56V ARC Lithium platform. The included 7.5Ah battery is the largest in EGO’s standard lineup, and the mower will also accept the 10Ah if you have one. Cutting deck is 21 inches. Six cutting height settings from 1.5 to 4 inches. The Select Cut system uses three blades: the setup mulches, bags, or side-discharges without swapping parts. The Touch Drive self-propel is variable speed, controlled by handle pressure. Weight with battery installed is approximately 68 lbs.

The battery charges to full in around 40 minutes with the rapid charger. With a standard charger, plan on closer to 4 to 5 hours.

Performance and Testing

Runtime

EGO quotes up to 60 minutes on the 7.5Ah battery. My actual results were consistently in the 45 to 55 minute range mowing at a normal pace through established fescue that needed cutting, not trimming. Thick late-spring growth with some moisture knocked that down to around 38 to 40 minutes. (I timed this across six separate sessions to get a reliable average.) For context, that handled just under an acre per charge in my conditions, which include a moderate slope toward the back of the mowed area.

If you’ve ever had a smaller battery mower fade to a near-stop in the last ten minutes because the charge is depleted, that won’t happen here. The 7.5Ah holds consistent power almost to the end, then drops off quickly rather than grinding down gradually.

Self-Propel

The Touch Drive system is the feature I’d highlight first to anyone replacing a gas mower. It responds to hand pressure on the bail rather than a separate speed lever, which means you’re not locked into a fixed pace. Walk faster, it speeds up. Slow down at the turn, it slows down. On a flat lawn this is a convenience. On a 15-degree slope it’s the difference between a manageable afternoon and a workout you didn’t sign up for.

Compared to the Husqvarna LC221RH, which I ran for three seasons before switching, the Touch Drive requires a short adjustment period but becomes natural quickly. The Husqvarna’s rear-wheel drive self-propel has more raw traction on wet grass; the EGO is better on dry slopes. Neither dominates the other completely, but the EGO’s pace responsiveness is more intuitive day-to-day.

Cut Quality

The Select Cut multi-blade system is the real upgrade over the LM2100. Three blades processing the clippings means finer mulch and less visible discharge on the surface. I ran it exclusively in mulch mode for most of the season, and on weekly cuts the results were clean enough that I stopped bagging entirely except before aerating in fall.

Side-discharge is adequate. Bagging capacity is reasonable at around 2.5 bushels, though if you’ve let the grass go two weeks you’ll be emptying it frequently.

Blade engagement is immediate and torque is consistent. There’s no warm-up lag, no choke adjustment, no priming bulb. Start button, walk.

Noise

My nearest neighbor is far enough away that this isn’t a primary concern for me, which I realize is not everyone’s situation. But the noise reduction is real: the LM2135SP runs at around 77 dB at the operator position versus the low 90s for a comparable gas push mower. Mowing before 8 a.m. without waking anyone is now a practical option rather than an antisocial one.

Pros and Cons

Pros.

• The 7.5Ah battery delivers runtime that matches the work, not just the spec sheet
• Touch Drive self-propel adapts to your pace rather than forcing yours to adapt to it
• Select Cut multi-blade system produces genuinely finer mulch than single-blade competitors
• No gas storage, no oil changes, no carburetor issues sitting over winter

• Full 56V platform compatibility: that battery runs EGO blowers, chainsaws, trimmers, and the EGO Pole Hedge Trimmer without any adapter

Cons.

• Tool-only version at around $449 is misleading value if you don’t already own a 56V battery
• 68 lbs with battery installed is heavier than most corded mowers and several gas competitors in this class
• Not a two-acre machine on a single charge; anyone mowing larger areas needs a second battery as a practical matter
• The rapid charger should be standard equipment at this price point, not an optional extra

Who It’s For

This mower is well-suited to anyone maintaining between a quarter-acre and an acre of lawn who is done with gas maintenance and wants a machine that handles real conditions. It’s particularly strong for properties with elevation changes that make pushing a full-size mower exhausting. If you’ve already got one or two tools on the EGO 56V platform, the battery compatibility alone justifies the platform consolidation.

It’s also worth mentioning in the context of the broader shift away from single-brand gas dependence. If you’re already running cordless tools from a 40V platform and wondering whether to invest in a higher-voltage system for heavier work, the LM2135SP is a reasonable anchor purchase for the 56V ecosystem. One battery running your mower, your blower, your chainsaw, and your edger is a practical simplification, not a marketing pitch.

It is not for.

Anyone with steep, difficult terrain that requires four-wheel-drive traction or a self-propel system with more pull than the Touch Drive provides. Not for properties over an acre and a half unless a second battery is already in the plan. And not, candidly, for buyers who will resist spending $249 on a spare battery, because this machine performs best when you don’t feel rushed to finish before the charge drops.

A Note on the EGO Platform More Broadly

The 56V ARC Lithium platform now covers over 80 tools. The battery that ships with this mower will also run EGO’s pole saws and battery chainsaws, hedge trimmers, and string trimmers. If you’re managing a larger property and want to explore the full scope of what the 56V system covers, the Battery and Cordless Tools section of this site has coverage across most of the major categories.

Worth mentioning: if your property has established hedgerows or wooded edges like mine does, pairing this mower’s battery with something like a battery-powered chainsaw from a compatible platform makes property management substantially more manageable. EGO and Stihl run separate platforms, so the batteries don’t cross, but the comparison is useful when you’re deciding which ecosystem to build.

Frequently Asked Questions

How long does the battery last on the EGO LM2135SP?

With the included 7.5Ah 56V battery, expect 45 to 55 minutes of actual mowing time under normal conditions, or around 38 to 40 minutes in thick or damp grass. EGO’s 60-minute claim is achievable under ideal conditions. The mower also accepts EGO’s 10Ah battery if you need extended runtime, which adds cost but pushes the usable window to around 70 minutes in practice.

Does the LM2135SP come with a battery and charger?

The kit version, currently around $699, includes the 7.5Ah battery and rapid charger. The tool-only version at approximately $449 includes neither. If you don’t already own a compatible 56V EGO battery, the kit is the better purchase. The 7.5Ah battery sells separately for around $249, which makes the tool-only version a poor deal unless you’re already in the ecosystem.

How does the EGO LM2135SP compare to a gas mower?

For most maintained suburban and semi-rural lawns, the LM2135SP performs comparably to a mid-range gas push mower in terms of cut quality and power. The tradeoffs favor the EGO in daily use: no oil changes, no fuel storage, no cold-start issues after winter storage, and roughly 15 dB quieter at the operator position. The gas mower has the edge for very large properties or situations where you need to keep going indefinitely without waiting on a charger.

Is 68 lbs too heavy for most users?

It is heavier than many people expect from a battery mower. On flat ground the self-propel system compensates for most of that weight, so the effort is lower than the number suggests. On slopes, the Touch Drive handles it well. Where weight becomes a real concern is when lifting it into a truck bed, maneuvering over obstacles, or folding it for storage. If physical limitations make a 68-lb machine difficult to handle, look at lighter options in the EGO lineup before committing to this model.

Can I use my existing EGO 56V batteries with this mower?

Yes. All EGO 56V ARC Lithium batteries are compatible across the platform. A 5.0Ah battery will run this mower, though with reduced runtime compared to the 7.5Ah. EGO recommends the 7.5Ah or larger for the LM2135SP given the motor demands. If you’re using this battery across multiple tools including a blower or a battery-powered edger from a compatible platform, factor in that heavy simultaneous use across tools will cycle through your battery inventory faster than single-tool use.
