The EGO STA1500 is a 15-inch string trimmer attachment designed for use with the EGO Power+ Multi-Head System. Rather than being a standalone tool, it connects to compatible EGO power heads (such as the PH1400 or PH1420), to turn that power unit into a cordless grass and edge trimmer.

The EGO STA1500 features a straight shaft made from solid steel, providing exceptional strength and durability for regular trimming tasks. The straight-shaft design improves reach and control, making it easier to trim around fences, garden beds, and other hard-to-reach areas. Its sturdy construction ensures the shaft remains rigid and reliable during use, giving users confidence while working.
In addition to its robust steel shaft, the STA1500 is built with high-quality materials that balance strength and lightweight handling. This reduces fatigue during longer sessions while maintaining excellent durability. The combination of solid construction and ergonomic design makes the trimmer attachment both reliable and comfortable for homeowners and garden enthusiasts alike.
The EGO STA1500 offers a 15-inch cutting swath, providing broad coverage for faster trimming and fewer passes. This wider cutting path is ideal for efficiently tackling medium-sized yards, clearing thick grass, or shaping lawn edges with precision. It delivers clean, uniform results, allowing users to complete trimming tasks more quickly without sacrificing accuracy or control.
Equipped with a 0.095-inch (≈2.4 mm) dual nylon cutting line, it ensures durability and smooth performance even on tougher vegetation. The dual-line design resists breakage, reduces the need for frequent replacements, and provides consistent cutting power, making it perfect for both residential and light commercial applications. This setup creates a highly efficient and reliable tool for maintaining a neat and professional-looking lawn.
The Rapid Reload Trimmer Head Technology on the EGO STA1500 is designed to make line replacement fast, simple, and frustration-free. Instead of disassembling the trimmer head or carefully winding line by hand, users can reload new line in seconds by inserting it into the head and twisting. This intuitive system minimizes downtime and keeps trimming tasks moving smoothly, especially during longer yard work sessions where frequent line replacement is common.
Moreover, the Rapid Reload head works together with a bump-feed mechanism, allowing the cutting line to advance easily while trimming. A quick tap on the ground releases more line, ensuring consistent cutting performance without stopping the tool. This combination of speed, convenience, and reliability makes the Rapid Reload Trimmer Head a standout feature for users who value efficiency and ease of use.
The STA1500 is fully compatible with EGO’s Multi-Head System, meaning it connects seamlessly to power heads like the PH1400 and PH1420. This modular approach allows users to switch between different attachments—such as hedge trimmers, brush cutters, and pole saws—without needing multiple standalone tools. By using a single power head, homeowners can handle a variety of garden tasks efficiently and cost-effectively.
Powered by EGO’s 56V ARC Lithium™ batteries, the STA1500 benefits from the same high-performance battery platform used across EGO tools. This ensures consistent power output and runtime while allowing users to share batteries between different tools in the system. The result is a flexible, convenient, and professional-grade trimming solution for lawns and gardens of all sizes.
Weighing just 3.51 lbs (1.59 kg) without the power head or battery, this attachment is lightweight and easy to handle. Its balanced design reduces fatigue during extended trimming sessions, allowing users to maneuver around obstacles such as trees, flower beds, and fences with minimal effort. This makes it ideal for both homeowners and professionals who need precision and comfort while working.
The ergonomic design, combined with smooth operation, ensures better control and a more enjoyable trimming experience. Even users with limited experience can quickly adapt to the tool, achieving clean edges and uniform results. Its user-friendly construction makes yard maintenance less tiring, helping users complete tasks efficiently while maintaining comfort throughout.
This attachment is built with durable, weather-resistant materials that protect it from moisture, dust, and light impacts. The high-quality housing and reinforced components ensure that it can withstand regular outdoor use, even in damp or unpredictable conditions. This durability helps maintain consistent performance and prolongs the lifespan of the tool.
All critical parts are designed to resist corrosion and wear, allowing the attachment to remain reliable throughout multiple seasons. Its robust construction means homeowners can leave it in their shed or transport it between jobs without worrying about damage, making it a dependable choice for year-round garden maintenance.
The EGO STA1600 String Trimmer Attachment offers excellent value for money by turning a single power head into a versatile trimming tool without the need to buy a separate cordless trimmer. Instead of investing in multiple standalone machines, users can expand their garden toolkit with additional attachments as needed, making each battery and power head purchase more cost‑effective over time.
When compared to similar petrol‑powered or dedicated cordless trimmers, it delivers comparable performance with far lower maintenance, noise, and operating costs. For homeowners who already own or plan to build out the ecosystem, the overall savings and long‑term utility make it a smart investment for regular yard care.

One of the first noticeable features of the STA1600 is its carbon-fiber shaft. EGO has clearly invested in premium materials here. Unlike aluminum or steel, carbon fiber provides incredible strength without adding unnecessary weight. The tool feels solid in hand, yet surprisingly easy to maneuver. Even during longer trimming sessions, the reduced strain on the arms becomes immediately apparent.
Beyond comfort, the carbon-fiber shaft offers long-term reliability. It resists bending, cracking, or warping—even under heavy use or when accidentally nudged against a fence or tree. With a lifetime warranty on the shaft when registered, this material ensures long-term peace of mind and durability. The difference between a well-designed tool and a cheap alternative is clear, and this attachment firmly belongs to the former category.
The EGO STA1600 offers a 16-inch cutting swath, delivering broad coverage for quicker trimming. This wider path reduces the number of passes required, saving both time and effort, especially in medium to large yards. Whether tackling thick weeds or maintaining clean lawn edges, the 16-inch width provides uniform, precise results. It strikes a balance between speed and control, making it suitable for residential and commercial use alike.
The attachment uses professional-grade 0.095-inch dual spiral-twist trimmer line, boosting cutting efficiency while minimizing line breakage. The spiral-twist design ensures smooth power transfer from the motor, maintaining consistent performance even when cutting dense grass or stubborn weeds. Users benefit from fewer interruptions and more reliable operation compared to standard trimmer lines, positioning this attachment as a top performer in its category.
The STA1600 supports EGO’s innovative POWERLOAD™ technology, which automatically winds new trimmer line into the head with the push of a button—when paired with compatible power heads like the PH1420. This eliminates the frustration many users face when manually loading trimmer line, making it a game-changing feature for both beginners and experienced landscapers. For anyone who trims frequently, the time and effort saved by POWERLOAD is a huge advantage.
When connected to older power heads like the PH1400, the STA1600 still offers Rapid Reload, a manual but simplified line-loading process. With Rapid Reload, you insert the line through the head, rotate the spool, and the line winds neatly into place without needing to disassemble anything. While not as effortless as POWERLOAD, it’s still far easier than traditional bump-head loading methods. Together, these systems ensure that no matter which power head you use, reloading line is quick and frustration-free.
EGO has always emphasized user comfort, and the STA1600 is no exception. Thanks to its lightweight carbon-fiber design and balanced construction, the attachment remains easy to maneuver even during long trimming sessions. Reduced vibration also improves user comfort, particularly for homeowners or professionals who spend extended periods maintaining landscapes. The intuitive attachment mechanism ensures a secure fit with EGO Multi-Head power units, creating a stable and comfortable trimming experience.
Even beginners find the attachment simple to operate, thanks to its straightforward assembly and compatibility with the ergonomic control systems built into EGO’s power heads. The adjustable handle and customizable power settings on EGO’s motors allow you to tailor your trimming experience to your height, strength, and specific yard conditions. Whether you trim weekly or only occasionally, the tool is designed to feel natural in hand and improve overall efficiency.
The STA1600 is fully compatible with the EGO POWER+ Multi-Head System, making it work with power heads such as the PH1400 and the latest PH1420. This modular approach allows users to own multiple attachments—including edgers, hedge trimmers, pole saws, and more—without buying separate motors each time. For users looking to build a complete outdoor tool system, this trimmer attachment is often one of the first and most essential additions.
This compatibility also allows it to leverage EGO’s powerful 56-volt ARC Lithium batteries, which are known for delivering long runtime, efficient cooling, and strong power output. With different battery sizes available (from 2.5Ah to 10.0Ah), users can choose the runtime that suits their yard size and workload. When paired with a high-capacity battery, this attachment can easily handle large trimming tasks without needing to stop for a recharge.
This attachment is built to withstand demanding outdoor conditions. Its IPX4-rated weather-resistant construction protects the attachment against water splashes and debris, allowing users to work reliably in wet or damp conditions. Components such as the bump head, guard, and drive system are reinforced to resist impacts from grass, stones, and other common yard obstacles, ensuring long-term durability.
The combination of carbon-fiber construction and rugged weather protection makes this attachment a dependable tool for extended professional use. Even with frequent exposure to outdoor elements, it maintains strong performance and structural integrity, reducing the need for maintenance or replacement. Users can rely on it to consistently deliver clean, precise cuts regardless of weather or terrain.
EGO provides a 5-year limited warranty on the STA1600 attachment, demonstrating strong confidence in its durability and performance. On top of that, the carbon-fiber shaft is backed by a lifetime warranty once registered, making it one of the most secure investments in the outdoor tool market. Few manufacturers offer this combination of robust coverage and high-grade materials.
This long-term warranty support makes the attachment a cost-effective choice for professionals and homeowners who want a tool that will last for many years. With minimal maintenance required and cordless convenience reducing fuel and repair expenses, this EGO trimmer attachment offers outstanding lifetime value. For anyone aiming to upgrade their trimming setup, it provides both exceptional performance and dependable protection.
