Pick the symptom - the matching free tool is one click away.
Compare exact mower models and kits—not just the battery voltage printed on them. For a useful shortlist, match the mower to your lawn and cutting needs, then compare its drive type, deck, claimed runtime, included battery and charger, handling, platform compatibility, and model-specific warranty. A 40V, 56V, or 60V label alone does not establish which mower cuts better or runs longer.
Start with the mower and the job
Before choosing a battery platform, identify the mower class that fits your lawn. Compare similar walk-behind models and check each model’s deck width, push or self-propelled drive, cutting-height range, and available mulching, bagging, or side-discharge options. Lawn area matters, but so do slope, grass conditions, obstacles, and how much effort you want the mower to provide.

Greenworks’ 40V walk-behind mower collection is a range rather than a single configuration. At the time the collection was reviewed in 2026, it listed 14 mowers, with deck-size filters from 14 to 25 inches and both push and self-propelled options. The collection also links to Greenworks’ 24V, 40V, 60V, and 80V lines, so check the exact Greenworks model rather than assuming every mower from the brand uses 40V. Greenworks 40V lawn mowers
One concrete Ryobi example
Ryobi lists the RY401180 as a 40V HP Brushless 20-inch self-propelled mower. Its product page specifies mulching, bagging, and side discharge, a 1.5-to-4-inch cutting-height range, and a 40V 6Ah battery with a quick charger. Ryobi describes the model as ideal for up to half an acre. These are specifications and claims for this model, not proof that it is equivalent to a particular EGO or Greenworks mower.

Compare runtime claims with the battery included
Runtime is specific to a mower, battery, and working conditions. Ryobi says the RY401180 can run for up to 40 minutes with its included 40V 6Ah battery. “Up to” is a manufacturer estimate, not a guaranteed mowing time; actual runtime can change with grass, cutting conditions, and operation. When comparing another model, find the manufacturer’s runtime statement for the exact battery supplied and consider whether the stated conditions resemble your yard.
Also check whether the listing is for a complete kit or a tool-only product. A mower without a battery or charger may not be a comparable purchase to one that includes both. Confirm the live listing’s contents before deciding whether you would need to buy a battery, charger, or spare separately.
Balance battery capacity against weight and handling
A larger-capacity battery can be relevant when you need more time between charges, but capacity alone does not tell you how comfortable a mower will feel. EGO’s battery-selection guidance asks users to consider the power and duration they need as well as battery weight and its effect on tool balance and feel. Apply the same practical check to any mower: compare the battery included, the batteries you may need to carry or swap, and how the mower is handled—not just the voltage or amp-hour number.

Check platform compatibility before counting batteries you own
Battery systems are brand- and platform-specific. Ryobi says its 40V batteries work with Ryobi 40V products, while EGO describes its platform as 56V ARC Lithium and says its batteries fit POWER+ tools. Do not assume a Ryobi, EGO, or Greenworks battery can power another brand’s tool. Verify compatibility for the exact battery and mower in the manufacturer’s product information or manual before treating an existing battery as part of the purchase plan. Ryobi 40V battery compatibility information
Existing batteries and chargers can make one ecosystem a more practical fit if they are documented as compatible with the exact mower. Ryobi describes its 40V system as having over 85 products, but that is a manufacturer’s system-size claim, not a reason to assume every product or battery combination is suitable. Check each tool’s compatibility details. Ryobi 40V battery details
Compare warranty terms for the exact model and market
Headline warranty lengths are useful only when the covered product and conditions match. Ryobi’s RY401180 page states a five-year tool warranty and a three-year battery warranty for that mower. EGO’s U.S./Canada warranty table varies by product and consumer or professional use; it includes five years for qualifying walk-behind mower tools and three years for standard ARC Lithium batteries and chargers, with exceptions and registration conditions for certain battery models. Greenworks says warranty terms vary by product and program and directs buyers to its current warranty terms. EGO U.S./Canada warranty policy Greenworks mower collection and warranty information

What the available specifications cannot settle
The manufacturer pages cited here do not establish a controlled head-to-head test of comparable Ryobi, EGO, and Greenworks mowers under the same lawn conditions. They therefore do not establish comparative cut quality, measured runtime, noise, long-term durability, repair rates, or total ownership cost. Treat manufacturer specifications and runtime estimates as information about the named product, not as independent rankings across brands.
