10 Best Lightweight Weed Wacker 2025 in the United States

The Worx String Trimmer Cordless GT3.0 is a lightweight and versatile tool, weighing about 6 pounds, which makes it easy to handle for most users. It runs on two included 20V lithium-ion batteries, providing cordless convenience and allowing you to use the same batteries with other Worx tools, which is great for anyone invested in that system. The 12-inch cutting width is adequate for trimming medium-sized lawns, offering a good balance between cutting area and maneuverability. The line diameter is 0.065 inches, which is fairly standard and suitable for regular grass and light weed trimming.

One standout feature is the tool’s ability to quickly switch between trimmer and edger modes, plus the head tilts 90°, helping you tackle edges and sloped areas with better precision. The addition of rubberized wheels supports edging work, guiding you for straighter cuts. The adjustable spacer guard helps protect plants and other yard features while trimming, which is handy for careful landscaping. The push-button Command Feed system offers instant line feeding, which simplifies operation without having to manually bump or pull the line.

While it’s light, some users might find 6 pounds a bit heavier compared to ultra-light models. Also, the 12-inch cutting swath is not ideal for very large or heavily overgrown areas, where a wider cutting path or more power might be needed. Assembly is required, which might be a small hurdle if you prefer ready-to-use tools. This Worx model suits homeowners looking for a cordless, lightweight, and easy-to-use trimmer and edger combo, especially for routine lawn care and neat edging.

The EGO POWER+ String Trimmer is a well-designed, battery-powered tool ideal for those wanting a lightweight yet powerful weed wacker. Weighing 7.5 pounds, it’s on the lighter side, which makes it easier to handle and reduces arm fatigue during long yard sessions. The 56V 4.0Ah battery provides solid cordless convenience, so you won’t be limited by a power cord. With a 16-inch cutting width, it covers a reasonable area efficiently — not the widest in its class but good for typical lawn maintenance.

The trimmer uses a 0.095-inch dual line, which is professional-grade and effective for tougher weeds and grass. Its telescopic carbon fiber shaft adjusts to your height, improving comfort and ergonomics, while the digital 2-speed selector gives some control over cutting power and battery life. The brushless motor is efficient and built to last, plus the weather-resistant construction means it can handle outdoor conditions well. Battery models like this are generally quieter than gas-powered trimmers.

One consideration is that the 7.5-pound weight may still feel a bit heavy for users seeking the absolute lightest tool, and the 16-inch cutting swath might require a bit more passes compared to wider models. However, the included battery and charger add value, and the 5-year tool warranty alongside a 3-year battery warranty shows confidence in build quality. This string trimmer is a great fit for homeowners looking for a reliable, easy-to-use, and moderately lightweight option for regular lawn and weed trimming.

The Greenworks 60V 13" Cordless String Trimmer & Leaf Blower Combo Kit is a solid choice if you're looking for a lightweight weed wacker. It weighs 22.1 pounds, which is reasonable for a combo kit that includes both a string trimmer and a leaf blower, but may still be a bit heavy for some users. The battery-powered design (60V, 4.0 Ah) ensures you won't be dealing with gas, oil, or emissions, which makes it low maintenance and environmentally friendly. The cutting width of 13 inches is adequate for most residential tasks, allowing you to cover a good amount of ground without being unwieldy.

The dual line bump feed head with a .080-inch line diameter makes reloading quick and easy, though some users might find the line diameter on the lighter side for tougher jobs. The ergonomics are a strong point, with the product designed to reduce user fatigue, making it comfortable to use for extended periods. In terms of noise, it’s quieter compared to gas-powered models, which is a plus if you’re looking for something that won't disturb your neighbors.

The included leaf blower offers powerful performance with 540 CFM air flow and 140 MPH air speed, which is great for clearing debris and wet leaves effectively. However, it's essential to note that the combo kit might be overkill if you only need a trimmer. The Greenworks combo kit is well-suited for homeowners looking for an efficient, low-maintenance solution for lawn care with the added benefit of a powerful leaf blower.
