Which one should you choose?
Choose RYOBI 40V 15-Inch Attachment Capable String Trimmer if
- You prefer a standalone 40V tool that does not require a separate power head.
- You want a lighter overall unit for basic trimming tasks.
- You are building a new RYOBI 40V system from scratch.
Choose EGO Power+ 16-Inch Carbon Fiber Trimmer Attachment if

- You want a lighter carbon fiber shaft with advanced line reload features.

EGO vs RYOBI Trimmer Specs
Cutting Width
The EGO Power+ STA1600 offers a 16-inch cutting swath, providing a slightly wider path per pass than the RYOBI 40V 15-Inch String Trimmer. This extra inch can reduce the number of passes needed for larger areas. The RYOBI model maintains a standard 15-inch width, which is common for many residential trimmers. While the difference is minimal, the EGO’s broader deck may offer a marginal efficiency gain during routine trimming tasks.
Build Material
Weight and durability are key factors in handheld tools. The EGO Power+ attachment uses a carbon fiber shaft, weighing just 3.4 pounds. This makes it significantly lighter and more durable than the RYOBI model. The RYOBI 40V string trimmer weighs 11 pounds. The substantial weight difference means the EGO tool will cause less fatigue during extended use. The carbon fiber construction also offers better resistance to impact and wear over time compared to standard materials.
System Integration
These tools represent different integration strategies. The RYOBI 40V unit is an attachment-capable bare tool, designed to connect to the EXPAND-IT system. This allows you to use it with various RYOBI power heads. The EGO STA1600 is specifically an attachment for the EGO Multi-Head system, compatible with PH1400 and PH1420 power heads. Both approaches offer versatility, but they are locked into their respective brand ecosystems. You must choose based on the power head system you already own or plan to buy.
Line Feed System
The EGO model features POWERLOAD technology, which allows you to feed the line by pushing a button, provided you use the PH1420 power head. It also supports Rapid Reload with the PH1400. The RYOBI 40V string trimmer does not list a specific advanced line feed system in its specifications. Standard bump feed is typical for this category. The EGO’s button-fed option offers faster reloading times, reducing downtime during heavy use compared to standard manual feeding methods.
Voltage and Power
Power sources differ between the two systems. The RYOBI tool operates on a 40V platform, while the EGO system uses a 56-Volt lithium-ion battery. The RYOBI claims more power than a 21cc gas trimmer. The EGO tool is an attachment that requires a compatible power head, which typically runs on 56V. Higher voltage often translates to more torque and sustained power. The EGO’s 56V system generally provides higher output than the 40V RYOBI platform, though specific motor amperage is not listed for either.
Choose the right trimmer for you
Users wanting a standalone gas replacement
The RYOBI 40V model functions as a complete bare tool. It delivers power comparable to a 21cc gas trimmer. Its 15-inch cutting swath handles standard edges. The 11-pound weight is manageable for general use. You save space with its EXPAND-IT attachment capability. This unit is ready to trim immediately after adding a battery.
Those prioritizing lightweight durability and width
The EGO STA1600 features a carbon fiber shaft for reduced weight. It weighs only 3.4 pounds, making it easier to hold for long periods. The 16-inch cutting swath covers more ground per pass. The unit includes a 5-year tool warranty. Its IPX4 rating provides weather resistance. This attachment suits users who already own a compatible power head.
Users seeking advanced line feed technology
This EGO attachment utilizes POWERLOAD technology for quick line refills. You push a button to feed the line and return to work. This feature works with the PH1420 power head. The Rapid Reload option offers an alternative method for the PH1400. The dual line spiral-twist design ensures consistent cutting. This system minimizes downtime during heavy trimming sessions.
