10 Best Lightweight Weed Wacker 2025 in the United States

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.

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 Greenworks 60V 16" Brushless Cordless String Trimmer is a solid choice if you're looking for a lightweight and powerful tool for trimming large areas. Weighing about 11.6 pounds with the battery, it’s light enough to handle easily, even for extended use, thanks in part to its 360° rotating handle designed to reduce wrist strain. Powered by a 60V brushless motor, it delivers a strong 6000 RPM speed, matching the power you'd expect from a mid-range gas trimmer, making it capable of cutting through thick weeds and even some stubborn vines.

With a 16-inch cutting width, it efficiently covers wide areas like long fence lines or overgrown yards, saving you time. The battery lasts up to 65 minutes and can cover around 1.5 acres per charge, which is suitable for medium to large properties, and it recharges relatively quickly in 45 minutes. Another plus is its low noise level, around 68dB, which allows early morning or late evening use without disturbing neighbors. The spin-to-load head design is user-friendly, letting you replace the trimmer line quickly without fiddling with manual winding.

While 11.6 pounds is light compared to some gas models, it is not the absolute lightest among cordless trimmers, so those looking for ultra-light tools might find it a bit heavy for detailed trimming tasks. Also, the included 2.5Ah battery offers good runtime but not the largest capacity available, so runtime may not be exceptional for very large areas. This makes it a well-rounded tool that suits homeowners seeking a balance of power, quiet operation, and ease of use in a cordless trimmer.
