Who This Suits
The Ryobi 40V Expand-It RY40270 is our “Best Value” pick for a reason. It’s designed for the homeowner who wants a solid, affordable cordless option without getting into gas maintenance. On the spec sheet, it offers a brushless motor and the Expand-It system at a price that undercuts most competitors. Owner feedback consistently highlights its ability to handle standard lawn trimming and light brush without breaking the bank. This trimmer suits those with a quarter-acre to half-acre lawn who are okay with swapping batteries for longer sessions. It’s also a smart choice for anyone already invested in Ryobi 40V tools, as battery compatibility saves significant money.
Cutting Power and Line Feed
Brushless Motor Performance
The brushless motor is the standout feature. Owners report it maintains steady head speed even in thick grass, avoiding the bog-down common with brushed trimmers. The 14-inch cutting width is narrower than many gas units, but this is an advantage for tight spots around fence posts and garden beds. It can handle patches of tall weeds like pigweed without stalling, though it’s not a brush cutter. For standard lawn trimming and light brush, it delivers sufficient grunt.
The Bump-Feed Head
The bump-feed head works reliably most of the time, but owners occasionally report jams. These typically occur when edging along hard surfaces (e.g., concrete walkways) and bumping too hard, requiring disassembly to clear tangled line. Using thicker .080 line (the factory line is .065) can also cause feed issues; sticking with the recommended .065 line ensures smooth operation. The bump action itself is responsive, requiring only a light tap on the ground to advance line.
Expand-It System in Real Use
As an Expand-It model, the power head accepts a range of attachments (trimmer, blower, edger, hedge trimmer) via a metal locking collar that clicks into place with no wobble. Owners who already own Ryobi attachments can save money by buying just the power head. The plastic housing on the head feels thin, especially around motor vents, but the attachment interface is built to last.
Battery and Runtime
The included 40V 2.0 Ah battery provides about 25 minutes of continuous trimming in tall, thick grass. This is sufficient for a smaller yard (half an acre of lawn), but owners with larger properties will need a second battery. Charge time is around 90 minutes. Using a 4.0 Ah battery (available separately) pushes runtime to about 45 minutes. The battery life is the biggest trade-off for the low price; gas trimmers typically run for an hour on a tank. The tool’s battery indicator (three lights) helps avoid mid-job dead batteries.
Cold Weather Note
In temperatures around 50°F, the battery holds up fine. However, in 30°F weather, runtime drops noticeably. Owners who trim in winter should plan for shorter sessions.
Handling, Balance and Comfort
The unit weighs under 10 pounds with the battery, allowing one-handed use for reaching under bushes. The adjustable handle uses a simple twist lock and suits a range of heights. The straight shaft provides good control for edging. After 30 minutes of trimming, owners report mild arm fatigue but no soreness—a clear advantage over heavier gas trimmers. The plastic housing keeps weight down; impacts with rocks leave scuff marks but no cracks in normal use.
Arm Fatigue Considerations
With a 4.0 Ah battery, a full hour of trimming can cause right forearm fatigue from holding the trigger. The trigger is a straight bar, not ergonomically shaped, and lacks a lock-on switch. Vibration is minimal, even at full throttle, which is a win over some cheap electric models.
Who Should Buy It
This trimmer is ideal for homeowners with a quarter-acre to half-acre lawn who want a lightweight, affordable cordless option without gas maintenance. It’s also perfect for those already using Ryobi 40V tools, thanks to battery compatibility. It suits light to medium trimming: edges, fence lines, flower beds, and around trees. The lightweight design makes it a good choice for older users or those with joint issues.
Who Should Skip It
Professionals or owners with more than two acres of rough terrain should look elsewhere. The plastic housing won’t survive daily commercial use, and the battery life will frustrate. Those who dislike bump-feed jams may prefer a trimmer with an automatic feed system.
Verdict
The Ryobi 40V Expand-It RY40270 delivers a capable, affordable tool for the weekend warrior. The battery life is the weak link, and the plastic housing raises questions about long-term durability. However, for the price, you get a brushless motor that cuts well, a lightweight design that reduces arm strain, and the Expand-It system that turns one power head into a blower, edger, or hedge trimmer. It starts every time with no pull cord, no gas smell, and low noise. Line feed jams are rare once users get accustomed to the bump head. If Ryobi offered a version with a larger battery and a metal head, it would justify a higher price. As a Best Value pick, this trimmer delivers exactly what it promises. Owners consistently recommend buying an extra battery for spring growth.
