10 Best Weed Wackers 2025 in the United States

The Greenworks 40V 13-Inch Cordless String Trimmer / Edger is a versatile tool that runs on a powerful 40V Lithium-Ion battery, which can also be used with over 75 other Greenworks tools. This ensures you don’t have to buy multiple batteries for different tools, which is convenient and cost-saving. The 13-inch cutting width is decent for handling medium-sized yards efficiently. Weighing 10.78 pounds, it's relatively lightweight, which helps reduce fatigue during extended use.

Additionally, the telescoping shaft allows you to adjust the tool's length to suit your height and posture, providing added comfort and ease of use. The 2-in-1 function lets you switch between trimming and edging with the push of a button, enhancing its functionality. The 90° pivoting head is handy for trimming and edging at different angles, making it more versatile. One of the standout features is the auto-feed line system, which automatically feeds the line as needed, eliminating the hassle of manual adjustments.

It also boasts a maintenance-free design—no need for gas, oil, or dealing with emissions, making it environmentally friendly and less messy. On the downside, some users might find the 13-inch cutting width a bit limiting for very large areas, and the single line feed might not be as robust for thicker weed patches. With a noise level on the quieter side, it's suitable for residential areas where noise might be a concern. This trimmer is particularly suitable for medium-sized lawns and users who appreciate ease of maintenance and lightweight design.

The BLACK+DECKER 20V MAX Cordless String Trimmer is a versatile 2-in-1 tool, functioning as both a trimmer and an edger. This makes it particularly useful for maintaining borders, sidewalks, and flower beds. One of its major strengths is its cordless design, powered by a 20V Lithium battery which provides a decent runtime. It's lightweight at 5.7 pounds, making it easy to handle, and features an adjustable height handle for added comfort during use.

The automatic spool feed system is a notable advantage, eliminating the need to stop and manually feed the line, which can be a hassle with some models. Additionally, the Powerdrive transmission provides efficient power to the cutting string, allowing you to complete tasks quickly and with less noise compared to more powerful gas-powered models, making it suitable for residential areas. However, the 12-inch cutting width might be a bit on the smaller side for larger yards, requiring more passes to cover the same area. The noise level is not specified, but being a battery-powered unit, it is generally quieter.

The included battery might also limit continuous usage duration, especially on larger properties, although it is part of the BLACK+DECKER 20V Max Power connect System, allowing battery swapping between compatible tools. This trimmer is best suited for small to medium-sized yards and those looking for a convenient, lightweight, and quiet tool for regular yard maintenance.
