In-depth review
The Ryobi 40V String Trimmer is a cordless outdoor power tool designed to make yard maintenance faster and more convenient without the hassle of gas, oil mixing, or pull-start cords. Built around Ryobi's 40-volt lithium-ion battery platform, this trimmer delivers strong cutting power for slicing through overgrown grass, weeds, and light brush along fences, garden beds, sidewalks, and other hard-to-reach areas. The brushless motor commonly found in Ryobi's 40V trimmer lineup runs cooler and more efficiently than brushed alternatives, extending both the tool's lifespan and the runtime you get from each battery charge, making it a reliable choice for homeowners who want dependable performance without constant maintenance.
Ergonomically, the trimmer is built with the everyday user in mind, featuring an adjustable telescoping shaft and a pivoting head that allows for comfortable operation at different heights and angles, whether you're trimming along the ground or reaching under shrubs. The included auto-feed or bump-feed string head keeps the line ready to go without frequent manual adjustments, so you can keep working through larger yards without stopping constantly to fix the feed. Many models in this Ryobi 40V trimmer series also offer a straight or split-shaft design, giving users the flexibility to attach compatible Ryobi Expand-It accessories, turning a single trimmer into a multi-tool solution for edging, pruning, and more.
Because it runs on battery power, this trimmer starts instantly with the pull of a trigger, eliminating the frustration of gas-powered pull cords and the fumes that come with them. It's noticeably quieter during operation, making it more pleasant to use around neighbors and family, while still providing the torque needed to tackle everyday lawn care tasks. Lightweight yet durable, the Ryobi 40V String Trimmer is built for the average homeowner who wants a low-maintenance, eco-friendly, and easy-to-store tool that fits seamlessly into a broader Ryobi 40V outdoor power equipment ecosystem, allowing battery and charger interchangeability across other Ryobi tools in the same voltage line.

What owners say
Switched from gas to this RYOBI trimmer and haven't looked back. It's quieter, lighter, and starts instantly every time.
Works well for most of my yard but I do need a second battery for larger areas. Still very happy with the performance.
No more mixing gas and oil. The auto-feed line system is convenient, though it occasionally jams if I let the grass get too tall.
Lightweight and easy to maneuver around flower beds. The adjustable shaft makes it comfortable for my height.
