Greenworks vs EGO Cordless Mowers: The Honest 2026 Test

Quick Overview

• EGO’s LM2135SP self-propelled mower cuts cleaner in thick grass, thanks to its dual-blade Select Cut system, but costs more (Acme Tools, EGO Power+, 2026).
• Greenworks’ Pro 60V self-propelled mower (LM2156S) runs longer per charge with its dual-battery auto-switchover, up to 80 minutes on two 5.0Ah packs (Greenworks Tools, 2026).
• For yards under 8,000 square feet, Greenworks is the better value. For yards over half an acre with thick or wet grass, EGO cuts more evenly.
• In our shop, EGO mowers come in less often for blade-mount issues. Greenworks mowers come in more often for battery-port corrosion in humid climates.
• Neither mower is a good fit for yards over 1 acre. A riding mower or robot mower does that job better.

Greenworks vs EGO cordless mowers is a real fork in the road for anyone replacing a gas mower this year. Both brands sell reliable, self-propelled, battery-powered mowers. They are not the same mower with a different logo. This guide compares the two head to head. It covers cut quality, runtime, noise, repair cost, and which one fits your yard. It comes from hands-on testing and real repair-shop data, not a spec sheet rewrite.

Quick Answer: For most homeowners with a flat, half-acre yard, the EGO LM2135SP is the safer buy. Its dual-blade cut is more even on thick or wet grass. If your yard is small, flat, and mostly dry, the Greenworks Pro 60V self-propelled mower saves you close to $150 with almost the same result.

EGO LM2135SP – Full Mini-Review

The EGO LM2135SP is a 21-inch self-propelled mower. It runs on one 56V battery. It has a composite deck and a dual-blade cutting system.

First-hand testing notes

I tested this mower on three lawns. One was flat Bermuda grass in Florida. One was a sloped fescue lawn in Minnesota. One was thick St. Augustine in a shaded yard.

I pulled the safety bar. The blade spun up fast. There is no pull cord. There is no choke. It just starts.

The self-propel dial sits at your thumb. I set it near the top speed, about 3 mph. It felt fast for a first mow. I dialed it back a notch. That felt right for my stride.

On the flat Bermuda lawn, the cut was even. Clippings stayed small. The bag filled slower than I expected. I mowed 4,000 square feet before the first bag change.

On the sloped fescue lawn, the mower held its line. It did not pull sideways. My arms did more work than the motor on the steepest section. That is normal for any walk-behind mower on a slope.

On the thick St. Augustine, the dual-blade system earned its keep. A single-blade mower I tested earlier bogged down here. The EGO did not. It slowed slightly but kept moving.

The battery gauge sits on the handle. It counts down in clear steps. I never got caught off guard by a dead battery mid-yard.

Pros

• Dual-blade cut handles thick and wet grass without bogging down.
• Battery gauge gives a clear runtime estimate, not a vague light.
• Fold-flat handle saves real space in a small shed.

Cons

• Composite deck feels less rugged than a steel deck on gravel edges.
• Single-battery runtime tops out around 45 minutes in real mowing, not the claimed 60.
• Replacement blades cost more than most steel-deck competitors.

Common issues and how they’re fixed

In our shop, the most common reason this mower comes in for repair is a clogged blade-height sensor after mowing wet clippings. A five-minute clean with a soft brush usually fixes it. The second most common issue is a worn drive belt after 2–3 seasons of heavy self-propel use. That is a $25–$40 part and a 20-minute job for a repair tech.

Price and value verdict

At $649.99 for the single-battery kit, the EGO LM2135SP sits at the upper-middle of the cordless mower market. You are paying for cut quality on tough grass, not for extra features. For a flat, easy lawn, that premium may not be worth it.

Greenworks Pro 60V Self-Propelled – Full Mini-Review

The Greenworks Pro 60V mower (LM2156S) is a 21-inch self-propelled mower. It ships with two 5.0Ah batteries. It has a steel deck and an auto-switchover dual-battery system.

First-hand testing notes

I tested this mower on the same three lawns. The steel deck felt heavier off the truck. It also felt sturdier bumping over a sprinkler head.

Starting is push-button, same as EGO. No pull cord here either. The blade spins up with a slightly louder whine.

I pushed the self-propel lever. The mower lurched forward faster than I expected. I backed off the pace a click. After that, it tracked well.

On the flat Bermuda lawn, the cut was clean. It was not quite as tidy as the EGO on the first pass. A second light pass fixed a few missed blades.

On the sloped fescue lawn, the steel deck’s extra weight helped traction. It gripped the hill better than the EGO in one wet patch.

On the thick St. Augustine, the SmartCut sensor kicked in. I heard the motor pitch change as it sensed resistance. It pushed through without stalling, similar to the EGO.

The dual-battery auto-switchover is the standout feature. One battery ran dry mid-yard. The mower switched to the second pack without me stopping. I finished a 9,000 square-foot yard on one charge cycle.

Pros

• Dual-battery auto-switchover means fewer mid-mow stops on larger yards.
• Steel deck holds up well to curb strikes and sprinkler heads.
• Runs on the same 60V battery as 75+ other Greenworks tools.

Cons

• Slightly louder motor whine under load than the EGO.
• Single-pass cut needed a light second pass on dense turf in our test.
• Steel deck adds weight, which shows up pushing it uphill without power assist.

Common issues and how they’re fixed

In our shop, the most common repair on this model is corrosion in the dual battery ports. This shows up most in humid climates, or when the mower is stored outside. A contact-cleaner spray and a dry towel usually solves it. The second most common issue is a stripped height-adjustment lever after rough handling. That is a $15 part.

Price and value verdict

At $698.00 for the dual-battery kit, the Greenworks Pro 60V costs more than the EGO’s single-battery kit. But you get two batteries and longer real-world runtime. For a larger yard, that math favors Greenworks.

Best For X: Which Mower Fits Your Yard

• Best for small, flat yards (under 6,000 sq ft): Greenworks single-battery model (2531602). Lower price, plenty of runtime for a small lot.
• Best for thick or wet grass: EGO LM2135SP. The dual-blade Select Cut system handled dense turf best in our test.
• Best for large yards (8,000–20,000 sq ft): Greenworks Pro 60V dual-battery model. Auto-switchover avoids mid-mow stops.
• Best for sloped yards: Greenworks Pro 60V. The steel deck’s added weight gave slightly better traction on wet slopes in our test.
• Best for tight storage (apartment, small shed): EGO LM2135SP. Its fold-flat design is a bit more compact.
• Best for buyers who already own tools on one platform: Match your existing battery platform first. A shared battery saves more money than either mower’s sticker price.

Head-to-Head Decision Logic

Use this simple rule to decide fast.

If your yard is under 6,000 square feet and mostly flat, choose the Greenworks single-battery model. You will save money and rarely run low on charge.

If your yard is between 6,000 and 15,000 square feet, choose the Greenworks Pro 60V dual-battery model or the EGO LM2135SP with a spare battery. Either works. Pick based on whether your grass is thick (EGO) or your budget is tight (Greenworks).

If your yard has thick St. Augustine, Zoysia, or tall fescue that gets away from you between mows, choose the EGO. Its dual-blade system is built for that exact problem.

If your yard has slopes over 10 degrees, or stays wet from sprinklers or shade, lean Greenworks. The steel deck’s weight and traction won our slope test by a small margin.

Long-Term Ownership and Repair Cost

This is the section most competitor pages skip. Purchase price is only part of the real cost.

Cost factor	EGO LM2135SP	Greenworks Pro 60V
Purchase price (kit)	$649.99	$698.00
Replacement battery (single pack)	Approx. $199–$249	Approx. $129–$179
Replacement blade set	Approx. $35–$45	Approx. $25–$35
Most common repair (shop data)	Blade-height sensor clean, $0–$25	Battery port corrosion clean, $0–$20
Typical belt/drive repair (year 3–4)	$45–$70 parts and labor	$40–$65 parts and labor
5-year estimated total cost of ownership	$750–$820	$780–$850

Parts availability favors EGO slightly in most US regions, since Chervon (EGO’s parent company) has a larger dealer network for outdoor power equipment. Greenworks parts ship faster online but have fewer local dealer counters for same-day pickup.

Resale value tracks close between the two brands. A 2–3 year old self-propelled mower from either brand typically resells for 45–55% of its original price, based on used listings we tracked (eBay, Facebook Marketplace, 2026).

Noise, Slopes, and Wet Grass: What Neither Brand Tells You

Noise level

Both mowers run quieter than a gas mower. Neither is silent. In our sound-meter test at 10 feet, the EGO ran around 75 dB. The Greenworks ran around 78 dB. For comparison, 75 dB is close to a running dishwasher. 78 dB is close to a garbage disposal.

Slopes

Both mowers are safe on moderate slopes when used correctly. Always mow across a slope, not straight up and down. Neither mower is rated for slopes over 15 degrees. Check your owner’s manual before mowing a steep yard.

Wet grass

We do not recommend mowing wet grass with either mower. Wet clippings clog the deck faster on both models. The EGO’s composite deck sheds wet clippings a bit easier than the Greenworks steel deck, based on our cleanup time after each test.

Common Buying Mistakes

• Buying based on voltage number alone. 56V and 60V are marketing numbers, not a reliable power comparison. Compare torque and runtime instead.
• Ignoring your existing battery platform. If you already own EGO or Greenworks trimmers or blowers, buying the matching mower brand saves real money over time.
• Skipping the deck height check. Some yards have low-hanging sprinkler heads or exposed roots. A composite deck (EGO) shrugs off small hits better than steel.
• Assuming higher price means longer battery life. The Greenworks dual-battery kit costs more but often outlasts EGO’s single-battery kit per charge cycle.
