EGO Power+ LM2142SP Self-Propelled Lawn Mower vs RYOBI 40V HP Brushless 21-Inch Self-Propelled Mower: Full Comparison
I've tested both EGO and RYOBI cordless mowers extensively, and they represent genuinely different philosophies in battery-powered lawn care.
The EGO Power+ LM2142SP sits at the premium end of the market for good reason. That 56V Arc Lithium battery system with Peak Power technology isn't marketing fluff—it actually delivers power equivalent to a 160cc gas engine. I've pushed this through overgrown grass that would choke most battery mowers, and it just keeps cutting. The 45-minute runtime from the included 5.0Ah battery handles most suburban lots up to 1/3 acre without issue. The steel deck construction feels tank-solid compared to polymer alternatives, and that variable-speed self-propulsion system (0.9 to 3.1 mph) adjusts smoothly without the jerky engagement you get from cheaper implementations.
RYOBI takes a different approach. Their 40V HP Brushless mower costs $100-200 less while still handling typical residential lawns without breaking a sweat. The brushless motor technology means better efficiency and longer lifespan for both the motor and battery. But here's where RYOBI really pulls ahead for many people: their 40V platform covers over 175 tools. String trimmers, blowers, chainsaws, workshop tools—the batteries work across everything. If you're building a complete cordless collection, that compatibility saves serious money over time.
For raw mowing performance on larger properties, EGO's higher voltage and steel construction justify paying more. The extra power means faster recovery when the mower bogs down in thick patches, and the longer runtime means fewer interruptions to swap batteries. But if your yard stays under 8,000 square feet and you maintain it regularly, RYOBI's 40V system handles the job while saving money upfront and giving you access to a much broader tool ecosystem. The 14-pound weight difference also matters if you're hauling the mower up stairs or loading it frequently.
Both systems last through 500-800 charge cycles before you notice capacity dropping off. Both include 3-year battery warranties and 5-year tool warranties. Charging times are nearly identical—60 to 90 minutes with rapid chargers for a full charge.
Your choice really depends on what you're optimizing for. EGO wins on pure cutting performance, runtime, and build quality. RYOBI wins on price, weight, and ecosystem breadth. Both beat gas mowers for maintenance headaches and emissions, which is the whole point of going battery-powered in the first place.

Frequently Asked Questions
Yes, and you'll notice the difference in challenging conditions. EGO's 56V system with Peak Power technology matches a 160cc gas engine, while RYOBI's 40V platform works great for normal suburban lawns but struggles more with thick, wet, or overgrown grass. If you push your mower hard, EGO's extra voltage makes a real difference.
Absolutely—all RYOBI 40V batteries work across their entire 175+ tool lineup. This is a huge advantage. EGO's battery ecosystem is excellent and covers about 50 tools, which is still pretty good, but RYOBI's cross-compatibility across so many products means you can share batteries between your mower, trimmer, blower, and even workshop tools.
EGO gives you about 45 minutes with a 5.0Ah battery, covering roughly 1/3 acre. RYOBI delivers 35-40 minutes with a 6.0Ah battery for about 1/4 acre. EGO's higher voltage system is more efficient at maintaining power under load, so you get more effective cutting time on larger properties.
Depends on your lawn and priorities. If you're mowing over 10,000 square feet, dealing with thick grass, or just want maximum runtime and that steel deck durability, EGO's $599-$699 price tag makes sense. But for well-maintained lawns under 8,000 square feet, RYOBI at $399-$499 delivers better value and you'll pocket the savings.
RYOBI wins here at 68 lbs versus EGO's 82 lbs. That 14-pound difference is noticeable when you're pushing, turning, or loading the mower. If you have slopes, stairs, or tight storage space, RYOBI's lighter weight matters. The difference comes from EGO's steel deck versus RYOBI's polymer construction.
It depends on your priorities. EGO dominates on raw power, runtime, and durability with its 56V system and premium steel construction—making it objectively better for larger properties and tougher mowing conditions. However, RYOBI is the better overall value and choice for most homeowners with typical yards who want lighter weight and access to a massive tool ecosystem.
Buy EGO if you have a larger property (over half an acre), demand premium performance, and plan to use it for years without replacement. Buy RYOBI if you have a smaller yard, want the best value, prefer lighter equipment, or are building a complete cordless tool collection where compatibility matters.
EGO uses a more powerful 56V battery system with longer runtime and heavier steel construction for durability, while RYOBI's 40V system is lighter, more affordable, and compatible with 175+ other tools. EGO excels at performance and longevity; RYOBI wins on value, portability, and ecosystem flexibility for typical homeowners.
