Ryobi String Trimmer Review: Power, Quiet Operation, and Runtime

Ryobi String Trimmer Review

Ryobi has carved out a notable space in the cordless outdoor power tools segment, particularly with their string trimmers. Combining battery-powered convenience with powerful cutting performance, Ryobi’s lineup offers options that appeal to homeowners seeking efficient lawn care solutions without the noise and hassle of gas models.

Performance and Power

The Ryobi 40V HP Brushless Carbon Fiber String Trimmer stands out for its impressive power output relative to its class. Utilizing a 40V battery platform with a high-performance brushless motor, this model delivers cutting strength comparable to a 25cc to 30cc gas engine, making it ideal for reclaiming thick grass and various weeds.

• Cutting Capacity: The trimmer supports cutting swaths of 15 or 17 inches, selectable by rotating the cutter head, and operates with line diameters from 0.080 to 0.105-inch, allowing users to tailor its cutting power to different lawn conditions.
• Speed Modes: It features a variable speed trigger with two speeds—low for lighter trimming and high for heavy-duty cutting, including tough grasses like St. Augustine.
• Runtime: Paired with a 6.0Ah battery, it offers over an hour (approximately 1:05:34) of continuous runtime on a 0.095-inch line, which is remarkable given the power it delivers. Using thicker 0.105-inch line reduces runtime somewhat but still remains competitive.

Users transitioning from gas string trimmers will find the power delivery strong and reliable, with a well-balanced combination of torque and speed that handles a range of yard tasks effectively.

Noise and Vibration

One of the key advantages of the Ryobi 40V HP trimmer is its quiet operation. Part of Ryobi’s Whisper Series, it runs approximately 60% quieter than a comparable gas-powered trimmer. Noise was measured at 84 dB(a) on low speed and 87 dB(a) on high speed, significantly less disruptive for both the operator and the neighborhood.

Additionally, the carbon fiber shaft contributes to a reduction in vibration. Early Ryobi battery trimmers suffered from high vibration, but improvements in shaft material and design have substantially smoothed operation. This makes the trimmer comfortable to use over longer periods and minimizes operator fatigue.

Design and Ergonomics

The Ryobi 40V HP Brushless trimmer features a lightweight yet sturdy carbon fiber shaft that weighs just 8.8 pounds as a bare tool and about 12.9 pounds with the 6.0Ah battery installed. The overall length measures just over 72 inches, giving the operator good reach and control.

• Handle Adjustments: Tool-free adjustments allow easy positioning to suit user preferences, enhancing ergonomics and balance.
• Split Shaft: The trimmer incorporates a split shaft mainly for shipping convenience, although breaking it down frequently for storage is not recommended.
• Compatibility: It works with all Ryobi 40V batteries, integrating into a large ecosystem of more than 75 Ryobi tools, making battery interchangeability simple for users with multiple devices.

Line and Cutting Head Features

Changing line on the Ryobi 40V HP trimmer is user-friendly with Ryobi’s Reel Easy design. The bump-feed dual-line head allows quick reloading without manual winding. Users simply align arrows, feed line to halfway, and turn the top section counterclockwise to load the line, making the process efficient and less frustrating.

To enhance versatility, the kit includes a secondary head option that accepts fixed lines or plastic blades. The plastic blade attachment provides higher mass for cutting thicker weeds that string alone struggles with, expanding the trimmer’s effectiveness in challenging weed control.

Additional Features

• Variable Speed Trigger: Permits precision control over cutting power and battery life.
• Not Attachment-Capable: Unlike some Ryobi models, this trimmer is a dedicated stand-alone tool and does not support interchangeable attachment heads.
• Rapid Charger: Included in the full kit, the charger restores the battery to full capacity within 60 minutes, minimizing downtime.

Ryobi 40V EXPAND-IT String Trimmer Overview

Separately, Ryobi also offers the 40V EXPAND-IT system, a highly versatile attachment-based string trimmer. This model features a 4.0 Ah battery, adjustable cutting swath from 13 to 15 inches, and supports bump-feed line advancement with 0.080-inch diameter line.

• Expandability: Users can detach the power head and swap in other Ryobi tool attachments, creating a multi-function system that saves space and money.
• Ergonomics: The EXPAND-IT model includes an ergonomic grip with rubber overmolding and a padded U-shaped handle that adjusts in height to accommodate different users, improving comfort during extended use.
• Reel-Easy Speed Winder: Replacing traditional re-spooling headaches, Ryobi’s speed winder lets users load 16 feet of line quickly and efficiently in under a minute.

Power and Usability Comparison

Customer Experience and Practical Insights

The Ryobi string trimmer models are generally praised for their quiet operation, light weight, and strong cutting performance. Unlike traditional gas models, these cordless trimmers provide a much quieter experience, making them practical for early morning or late-night use without disturbing neighbors.

In trials, users have found the battery life sufficient for moderate to large yards, with runtime around 40 minutes to over an hour depending on usage and line thickness. The soft start and variable speed controls contribute to ease of use by offering gradual acceleration rather than sudden bursts of power.
