10 Best Lightweight Weed Eater 2025 in the United States

The Worx String Trimmer Cordless GT3.0 20V is a versatile option for those looking for both a trimmer and an edger in one tool. Weighing in at 6 pounds, it is lightweight and easy to handle, making it suitable for prolonged use without causing strain. The cordless design, powered by two 20V lithium-ion batteries, ensures flexibility and convenience, allowing you to move freely without being tethered to an outlet. The included batteries are also compatible with other Worx tools, adding to its versatility.

With a cutting width of 12 inches, it strikes a balance between efficiency and precision, suitable for small to medium-sized yards. The line diameter is 0.065 inches, which is standard for light to moderate trimming tasks. The instant line feed system is a handy feature, enabling quick adjustments without interrupting your workflow. Ergonomically, the trimmer is designed with rubberized wheels for better control and a head that tilts 90 degrees, making it easier to trim on sloped terrains and reach difficult areas. The adjustable spacer guard protects plants and lawn ornaments, which is a thoughtful addition for garden enthusiasts.

The need to assemble the trimmer might be a minor inconvenience for some users. Additionally, while it offers good performance, it may not be powerful enough for heavy-duty or commercial-grade tasks. It's best suited for residential users with typical garden maintenance needs.

The BLACK+DECKER 20V MAX Cordless String Trimmer (LST300) stands out in the lightweight-weed-eater category due to its ease of handling and versatility. Weighing only 5.7 pounds, it's lightweight and easy to maneuver, making it ideal for users who may struggle with heavier equipment. The adjustable height handle further enhances its ergonomics, allowing for comfortable use over extended periods.

This trimmer is powered by a 20V lithium battery, which provides a decent runtime thanks to runtime extension technology and the included 2 Ah battery pack. The automatic spool feed technology is a notable feature, eliminating the need for manual line feeding and ensuring smoother operation. Additionally, the 12-inch cutting width is sufficient for most residential trimming tasks, and the pivoting handle adds versatility by enabling easy conversion between trimming and edging modes.

However, while the powerdrive transmission offers better power delivery, it may still struggle with very thick or tough overgrowth compared to more powerful, corded models. Noise levels are relatively low, which is a plus for those who prefer quieter tools. Users should also note that assembly is required, which might be a slight inconvenience for some. In summary, this trimmer is well-suited for homeowners looking for a lightweight, battery-powered solution for regular lawn maintenance, though it might not be the best choice for heavy-duty trimming tasks.

The Greenworks 60V 16” Brushless Cordless String Trimmer is a solid choice for those looking for a lightweight and efficient weed eater. Weighing 11.58 pounds, it's relatively light, especially compared to gas-powered models, making it easier to handle and reducing user fatigue. The battery-powered design (with a 2.5Ah battery included) ensures a quieter operation and up to 65 minutes of runtime on a full charge, ideal for medium-sized yards.

The 16-inch cutting width allows for efficient trimming and edging, while the dual line bump feed head with a 0.095-inch line diameter makes it easy to reload and tackle tough grass and weeds. The brushless motor adds to its durability, providing more power and longer run-times. However, some users might find the noise level slightly higher than expected for an electric model. Its ergonomic design and lightweight nature provide comfort and control, although the 11.58 pounds might still be a bit heavy for some users during extended use.
