Choose the Ryobi 40V trimmer for attachment options; choose the EGO 56V trimmer for a lighter tool and a brushless motor. The right pick depends on whether you value a multi-tool platform, lower listed weight or a battery setup that matches tools you already own.

The Ryobi kit has an adjustable 13 to 15 in cutting width and comes with a 4.0 Ah battery and charger. The EGO ST1502SA has a fixed 15 in swath, a 2.5 Ah battery and charger, and works with EGO 56V ARC Lithium batteries.

The Ryobi Carbon Fiber Expand-It model is a separate option for shoppers who already have RYOBI 40V batteries. It has a brushless motor and attachment capability, but comes without a battery or charger.

Ryobi 40V trimmer vs EGO 56V trimmer: what changes?

The main differences are attachment support, listed weight and battery platform. The Ryobi kit is built around Expand-It attachments; the EGO ST1502SA focuses on a 15 in cutting swath and its 56V battery platform.

The Ryobi kit weighs 13.9 lb and includes a 4.0 Ah battery and 90-minute charger. The EGO weighs 7.4 lb, and its included 2.5 Ah battery charges in 50 minutes with the included charger.

Those weights describe the tools as specified, but the available product details don't tell you whether each figure includes a battery. Use them as a rough comparison and check the exact configuration before buying.

Which is easier to handle for a full yard?

The EGO has the lower listed weight, while the Ryobi gives you a narrower cutting-width setting. Either difference may matter more than voltage if you trim for a long stretch or work around tight beds and fences.

At 7.4 lb, the EGO's listed weight is lower than the Ryobi kit's 13.9 lb. Balance and grip also affect comfort, so the number alone can't tell you how either tool will feel in your hands.

The Ryobi kit can be set from 13 to 15 in. A narrower path may help you avoid nearby plants or trim close to posts, while a wider path covers more ground per pass.

The EGO keeps its 15 in cutting swath. If you want to compare options by tool weight, see our guide to how much a string trimmer weighs.

Does the Ryobi carbon fiber model change the weight comparison?

The Ryobi Carbon Fiber Expand-It model is listed at 7 lb, but it doesn't include a battery or charger. Compare its weight with a complete tool setup, not as if it were ready to use out of the box.

It works with RYOBI 40V lithium-ion tools and batteries and accepts Expand-It attachments. Its brushless motor and two-speed trigger add features for shoppers who already own compatible Ryobi batteries.

If you're comparing cordless options by voltage, our 40V vs 20V trimmer guide explains why battery voltage is only one part of the choice.

How do the batteries and charging compare?

The Ryobi kit includes a higher-capacity 4.0 Ah battery, while the EGO kit includes a 2.5 Ah battery and a stated charge time of 50 minutes. Battery capacity and charge time help describe the setup, but they don't guarantee a direct runtime comparison between the two tools.

The Ryobi kit includes a 90-minute charger. The EGO package includes its 56V 2.5 Ah battery and charger, which is described as charging that battery in 50 minutes.

EGO gives an estimated runtime of up to 45 minutes on a charge. Don't assume the Ryobi will run longer just because its included battery has a higher amp-hour number; motor draw, line and cutting conditions affect actual work time.

If you already own batteries, platform compatibility can shape the value more than the included pack. The Ryobi Carbon Fiber model works with RYOBI 40V batteries, while the EGO ST1502SA works with EGO 56V ARC Lithium batteries.

Which head and line setup suits your work?

The Ryobi kit offers a bump-feed head and adjustable cutting width; the EGO has a Rapid Reload head and a stated 0.095 in line. Choose based on how you prefer to feed line and whether a specific line size matters for your yard.

The Ryobi kit's Reel-Easy bump-feed head is designed for reloading, and its included line is 0.080 in twisted line. The EGO Rapid Reload head is designed to make loading new cutting line quick and easy.

EGO's 0.095 in line is thicker than the Ryobi kit's 0.080 in line. That difference alone doesn't prove the EGO is better for every task, since suitable line depends on the trimmer and the grass or weeds you cut.

Check your manual before changing line size. Our guide to choosing the right string trimmer line size explains how line choice affects trimming.

Which one works with your other yard tools?

Choose the Ryobi kit if you want one power head that accepts compatible attachments; choose the EGO if you want to stay within its 56V battery platform. Compatibility can save space and reduce the number of separate tools you need to store.

The Ryobi kit accepts RYOBI Expand-It attachments and other universal gas attachments. The Carbon Fiber model is also attachment capable, though Ryobi advises checking compatibility before purchase.

The EGO ST1502SA works with EGO 56V ARC Lithium batteries. The listed details don't say that this trimmer accepts attachments, so don't assume that capability from the battery platform alone.

Our comparison of EGO and Greenworks string trimmers looks at another battery-platform choice. If attachments are central to your decision, our guide to string trimmers with attachments covers the feature in more detail.

Which trimmer should you choose?

Pick the Ryobi kit for Expand-It attachment support and an included 4.0 Ah battery; pick the EGO for a lower listed weight, a brushless motor and a 15 in swath. If you already own compatible batteries, start with the platform you have.

The Ryobi Carbon Fiber model fits a different buyer: someone who owns RYOBI 40V batteries and wants a brushless, attachment-capable power head. Remember to account for its missing battery and charger when comparing the total setup.

Which Ryobi or EGO trimmer matches your yard?

Choose by the work you expect to do, the tools you already own and the weight you can comfortably manage. The EGO suits shoppers who want a lighter listed tool with a 15 in swath, while the Ryobi kit suits buyers who want attachment options.

Choose the Ryobi Carbon Fiber model if you already have a compatible 40V battery and want to add a brushless attachment-capable power head. For an EGO 56V setup with a battery and charger included, the ST1502SA is the more complete starting point.

If either choice leaves you uncertain about cutting width or line, review the string trimmer buying guide before you decide.

Frequently asked questions

Is a Ryobi 40V trimmer more powerful than an EGO 56V trimmer?

Voltage alone doesn't settle which trimmer will cut better in your yard. The EGO model uses a 56V battery and a brushless motor, while the Ryobi kit uses a 40V battery and offers an adjustable 13 to 15 in cutting width.

Match the tool to your grass, line and work time.

Which trimmer is lighter, Ryobi or EGO?

The EGO ST1502SA has a listed weight of 7.4 lb, while the Ryobi attachment capable kit weighs 13.9 lb. The Ryobi 40V Carbon Fiber model is listed at 7 lb, but that power head comes without a battery or charger, so compare complete setups as well as tool weights.

Can you use attachments with both trimmers?

The Ryobi kit accepts RYOBI Expand-It attachments and other universal gas attachments, and the Ryobi Carbon Fiber model works with Expand-It attachments. The EGO ST1502SA product details don't state attachment capability, so check exact compatibility before choosing it for a multi-tool setup.

Do both trimmers include a battery and charger?

The Ryobi attachment capable kit includes a 4.0 Ah battery and 90-minute charger, and the EGO ST1502SA includes a 2.5 Ah battery and charger. The Ryobi Carbon Fiber Expand-It model includes neither, so it makes more sense if you already have a compatible battery and charger.

Which trimmer has a wider cutting path?

Both the EGO ST1502SA and the Ryobi attachment capable kit can cut a 15 in path. The Ryobi kit can also be adjusted down to 13 in, which gives you a narrower path option when you want to favor longer runtime over covering more ground per pass.
