Ryobi 40V HP Brushless 16" Carbon Fiber Shaft String Trimmer

Switching from a gas-powered string trimmer to the Ryobi 40V HP Brushless 16" Carbon Fiber Shaft String Trimmer has been a transformative experience. As an avid gardener with a one-acre property, I needed a tool that could handle extensive trimming without the hassle of gas and oil. This trimmer exceeded my expectations in several areas, although it did come with a few quirks.

Assembly and Build Quality

Assembling the trimmer was straightforward. The package includes a bump feed head, a bladed head, and some extra string. Attaching the guard to the trimmer head and connecting the assist handle to the powerhead shaft took only a few minutes. The carbon fiber shaft is not only lightweight but also adds a touch of durability to the overall construction. However, the assembly instructions could use some improvement. They were a bit confusing and lacked clear diagrams, making the process more time-consuming than it should have been.

Power and Performance

One of the standout features of this trimmer is its power. The brushless motor provides a performance comparable to a 27cc gas trimmer, making quick work of even the toughest weeds and grass. The variable speed trigger with a 2-speed switch allows for better control, especially when trimming around delicate areas like tree trunks. The adjustable cutting swath from 14" to 16" adds to its versatility, making it suitable for both large and small tasks.

I was particularly impressed with the runtime. With a 40V 4Ah battery, I was able to get over 45 minutes of continuous use on a single charge. This is more than enough to cover my entire property, and the battery charges relatively quickly, reducing downtime. However, the trimmer is a bit heavier than I expected, especially when using a 6Ah battery, which can be a drawback for extended use.

Usability and Comfort

Using the trimmer is a breeze, thanks to its ergonomic design. The lightweight carbon fiber shaft and adjustable handle make it comfortable to use, even for extended periods. The quick line reloading system is another convenient feature, allowing for easy string replacement without any tools. However, I did notice a slight delay in the throttle response, which can be a bit frustrating when you need to change speeds quickly. This seems to be a common issue with brushless motors and is something to consider if you frequently adjust the string speed based on the grass density.

Expandability and Versatility

One of the biggest advantages of this trimmer is its compatibility with the RYOBI EXPAND-IT attachments and other universal attachments. I tested it with the brush cutter and gutter blower attachments, and both connected seamlessly. This expandability makes the trimmer a versatile tool that can handle a variety of tasks, from trimming to edging and even blowing leaves.

Noise and Vibration

While the trimmer is quieter than any gas-powered model I've used, it does produce more noise than I expected for an electric unit. The motor and trimmer head generate a noticeable amount of vibration, which can be uncomfortable over time. However, this is a minor trade-off for the power and performance it delivers.

Durability and Maintenance

Durability is always a concern with outdoor tools, and this trimmer holds up well in most aspects. The carbon fiber shaft and overall build quality are impressive. However, I did encounter some issues with the string feeder. The line tends to break off inside the spool, requiring frequent re-stringing. This can be annoying and time-consuming, but it's a minor inconvenience compared to the benefits.

Maintenance is minimal compared to gas trimmers. There's no need for mixing gas and oil, and the electric motor eliminates the hassle of pull-starts and exhaust fumes. This makes the trimmer more environmentally friendly and easier to use, especially for those who are not mechanically inclined.

Customer Service and Warranty

Ryobi's customer service is commendable. I had an issue with my initial unit, which was resolved quickly through Home Depot and Ryobi's customer support. The trimmer comes with a 5-year limited warranty, which adds peace of mind and underscores the brand's confidence in their product.

Final Thoughts

The Ryobi 40V HP Brushless 16" Carbon Fiber Shaft String Trimmer is a powerful, versatile, and convenient tool that offers a significant upgrade from gas-powered models. Its compatibility with various attachments, impressive runtime, and minimal maintenance make it an excellent choice for homeowners with medium to large properties. While the throttle response and assembly instructions could be improved, these are minor drawbacks in an otherwise outstanding tool.

I highly recommend this trimmer for anyone looking to switch from gas to electric. Its power, ease of use, and expandability make it a worthwhile investment that will simplify your yard maintenance tasks and reduce your environmental footprint.
