EGO POWER+ Electric Lawn Mower, Self-Propelled Cordless with Select Cut and Touch Drive, Includes 56V 7.5Ah Battery and Rapid Charger – LM2135SP Review

Overview

The EGO POWER+ LM2135SP is a 21-inch, self-propelled cordless electric mower that aims to replace your gas mower without the hassle of fuel, oil changes, or pull cords. It’s built for homeowners with medium to large lawns (up to about half an acre) who want serious power, variable-speed self-propulsion, and the convenience of instant start. With the included 7.5Ah battery and rapid charger, this is EGO’s flagship consumer model, designed to deliver gas-like performance with zero emissions.

Who Should Buy This

1. Homeowners with 1/3 to 1/2 acre lawns – The included 7.5Ah battery will handle most of your yard on a single charge, especially if you use the self-propelled feature sparingly. This is not a toy for postage-stamp lawns.

2. Ex-gas mower owners tired of maintenance – If you’re sick of winterizing, draining gas, changing oil, and cleaning carburetors, this is your escape. The LM2135SP starts instantly with a push of a button, and maintenance is limited to blade sharpening and battery storage.

3. Homeowners with slopes or large flat yards – The Touch Drive self-propulsion system lets you dial in your walking speed from a crawl to a brisk jog. It’s especially useful on gentle slopes or if you have a long, flat lawn and want to move quickly.

4. Eco-conscious buyers who still want power – This mower cuts cleanly through thick grass, mulches well, and produces no fumes. If you want to ditch gas but refuse to compromise on cut quality, this is your target.

Key Features Breakdown

• 56V 7.5Ah ARC Lithium Battery – This is EGO’s largest consumer battery. It gives you real-world runtime of about 45–60 minutes of continuous mowing, depending on grass thickness and self-propelled use. It also works with all other EGO 56V tools, so you can share batteries across your trimmer, blower, etc.

• Select Cut Technology – You can switch between a single blade (for standard mulching or bagging) and a dual-blade setup (for finer mulching or better lift in tall grass). The dual-blade mode uses more battery but gives a noticeably cleaner cut, especially in tough conditions.

• Touch Drive Self-Propelled System – Instead of a lever or paddle, you control speed by squeezing or releasing the handlebar. The more you squeeze, the faster it goes. It’s intuitive and lets you match your walking pace exactly. The variable speed range is 0.9 to 3.1 mph.

• 21-Inch Steel Deck – That’s a full-size cutting width, same as most gas mowers. It’s stamped steel, not plastic, so it’s durable and handles bumps without cracking. It also has a 10-gauge steel deck on the top for extra rigidity.

• Rapid Charger Included – This charges the 7.5Ah battery from empty to full in about 2 hours. That’s fast enough to charge during lunch or between mowing sessions if you have a large lawn and a second battery.

• Push-Button Start – No choke, no primer, no pull cord. Press the button and go. It’s as simple as starting a power tool.

Pros

1. Excellent cut quality – The dual-blade Select Cut mode gives a clean, even cut even in thick, damp grass. It mulches fine enough that you rarely need to bag.

2. Intuitive self-propulsion – The Touch Drive system is one of the best in the cordless category. It’s smooth, responsive, and easy to feather for precise control on slopes or around obstacles.

3. Long runtime with the included battery – Most users can finish a 1/3-acre lawn on a single charge. If you’re pushing half an acre, you might need a second battery, but the included one is generous.

4. Low maintenance – No gas, no oil, no filters, no spark plugs. Just charge the battery, sharpen the blade once or twice a season, and you’re done.

5. Quiet operation – At about 80 decibels, it’s noticeably quieter than a gas mower. You can mow early morning or late evening without bothering neighbors.

6. Build quality – The steel deck feels solid, the handle is sturdy, and the battery locks in securely. It doesn’t feel like a toy.

Cons

1. Self-propelled drains battery fast – If you use the self-propelled feature aggressively (especially on thick grass or hills), you’ll see runtime drop significantly. In heavy conditions, you might get only 30 minutes.

2. Can struggle in very tall, wet grass – Like most electric mowers, it bogs down if you let the grass get too tall or if it’s soaking wet. You’ll need to mow more frequently than with a gas mower.

3. No rear discharge option – You get side discharge, mulching, or bagging. That’s fine for most, but some gas mowers offer rear discharge for tall grass. This isn’t a dealbreaker, but it’s worth noting.

4. Pricey for a cordless mower – At $600, it’s not cheap. You’re paying for the battery ecosystem and premium features. If you’re on a tight budget, there are cheaper cordless options, but they won’t match this mower’s performance.

Bottom Line

The EGO POWER+ LM2135SP is one of the best cordless mowers you can buy for a medium to large lawn. It delivers gas-like cutting power, excellent self-propulsion, and genuine convenience. The battery life is generous for most homeowners, the cut quality is top-tier, and the build quality inspires confidence. If you’re ready to ditch gas and have a lawn that’s between 1/4 and 1/2 acre, this is the mower to get. It’s not cheap, but it performs well enough that you won’t miss your old gas mower. Highly recommended.

Frequently Asked Questions

Q: How long does the 7.5Ah battery last on a full charge? A: In typical conditions (flat lawn, dry grass, moderate self-propelled use), expect about 45–60 minutes of runtime. If you’re mulching thick, tall grass with the dual-blade mode and using self-propelled aggressively, you might get 30–35 minutes. A 1/3-acre lawn is usually doable on one charge.

Q: Can I use the included battery with other EGO tools? A: Yes. The 56V ARC Lithium battery is compatible with all EGO 56V tools, including trimmers, blowers, chainsaws, and snow blowers. That’s one of the big advantages of buying into the EGO ecosystem
