RYOBI vs BLACK+DECKER Trimmer Specs

Cutting Width

Edge: RYOBI 40V 15-Inch Attachment Capable String Trimmer

The RYOBI 40V 15-Inch String Trimmer offers a 15-inch cutting swath, while the BLACK+DECKER 40V 13-Inch String Trimmer and Edger provides a 13-inch cutting width. A wider swath means you cover more ground with each pass. This makes the RYOBI model slightly more efficient for larger lawns where speed matters. The BLACK+DECKER unit is narrower, which may offer better maneuverability in tight spaces. Both are adequate for standard residential yards, but the extra two inches on the RYOBI give it a practical edge for clearing larger areas quickly.

Weight and Build

Edge: BLACK+DECKER 40V 13-Inch String Trimmer and Edger

Weight significantly impacts user fatigue during extended trimming sessions. The RYOBI trimmer weighs 11 pounds, whereas the BLACK+DECKER model is lighter at 7.8 pounds. The lighter BLACK+DECKER design reduces strain on your arms and shoulders, making it easier to hold for longer periods. The RYOBI unit is heavier, likely due to its robust attachment-capable shaft. If you plan to trim for long durations or have limited strength, the lighter BLACK+DECKER option is more comfortable. For those who prefer a sturdier feel, the RYOBI might suit your preference.

Versatility Features

Edge: Tie

The BLACK+DECKER 40V 13-Inch String Trimmer and Edger is a 2-in-1 tool that converts from a trimmer to an edger in seconds. This adds value if you need to edge walkways or flower beds without switching tools. The RYOBI 40V 15-Inch String Trimmer is attachment-capable, allowing you to connect other EXPAND-IT tools like a hedge trimmer or blower. This expands your system beyond just trimming. The BLACK+DECKER offers immediate versatility for edging tasks, while the RYOBI offers broader system compatibility for various yard jobs.

Power Transmission

Edge: BLACK+DECKER 40V 13-Inch String Trimmer and Edger

The BLACK+DECKER model features a PowerDrive Transmission, which delivers more power from the motor to the cutting string. This helps it tackle thick weeds more effectively than standard transmissions. The RYOBI claims more power than a 21cc gas trimmer, indicating strong torque for tough vegetation. Both tools are designed for heavy-duty performance. The BLACK+DECKER explicitly highlights its transmission technology for efficiency, while the RYOBI focuses on its overall gas-replacement capability. You get robust power from both, but the BLACK+DECKER specifies its mechanical advantage for cutting dense growth.

Line Feed System

Edge: BLACK+DECKER 40V 13-Inch String Trimmer and Edger

The BLACK+DECKER 40V 13-Inch String Trimmer and Edger includes an Automatic Feed Spool (AFS) system. This supplies trimmer line as needed without requiring you to bump the head on the ground. The RYOBI 40V 15-Inch String Trimmer data does not specify an automatic feed system, implying it likely uses a standard bump-feed mechanism. Automatic feed enhances convenience and keeps you cutting continuously. This is a clear advantage for the BLACK+DECKER if you want to minimize interruptions during trimming. The RYOBI may require more manual adjustment of the line during use.

Its attachment-capable shaft allows you to connect other EXPAND-IT tools, saving space and money.

Our pick: BLACK+DECKER 40V 13-Inch String Trimmer and Edger

This BLACK+DEcker trimmer weighs just 7.8 pounds, making it significantly lighter and easier to handle for extended periods. It converts to an edger in seconds.

You need runtime control and fast charging

Our pick: BLACK+DECKER 40V 13-Inch String Trimmer and Edger

The PowerCommand Dial lets you switch between maximum power for thick weeds or maximum runtime for larger areas. This flexibility helps you manage battery life effectively. The included fast charger restores full power in two hours or less. The state of charge indicator keeps you informed during use, ensuring you are never caught off guard by a low battery.
