Best String Trimmers in 2027

The Greenworks ST60L413 leads our ranking. It runs on a 60 V battery rated at 240 Wh, and both figures are the highest among the 20 products on this page. Battery energy sets how much work you get from one charge. The listing says it has a brushless motor for thicker grass and demanding yard tasks.

The cutting swath is 16 in, the widest of all 20 products. A wider swath means fewer passes across a medium or large yard. The line is 0.095 in thick, the same as the EGO and thicker than the 0.065 in line on three other models. The Load N' Go head is meant to speed up reloading, and an adjustable shoulder strap spreads the load.

Weight is the tradeoff. At 18.7 lb it is the heaviest of the 17 products that list weight. Plan on wearing the strap. It also comes with a 4-year warranty and a battery and charger. Attachment-capable design lets you add compatible Greenworks tools to the same shaft.

The EGO ST1502SA ranks second on our list. It pairs a 15 in cutting swath with a weight of 7.4 lb, so it is far lighter than the top-ranked Greenworks while cutting nearly as wide. The listing credits its brushless motor with low vibration, increased reliability, and long lifespan.

Power comes from a 56 V system with a 140 Wh battery. The listing claims up to 45 minutes of runtime on the included 2.5Ah battery. It charges in 50 minutes with the included charger. Variable speed lets you match the speed to the job. Only four of the 20 products list a runtime.

The line is 0.095 in, tied for the thickest listed. Line diameter affects how well the string cuts thicker growth. The head is a Rapid Reload type with bump feed. The 5-year warranty is the longest among the models that list one. This is the pick for a buyer who wants a capable all-around trimmer without carrying extra weight.

The HortiHub HG0556-AOR ranks third. It is a 21 V cordless trimmer with a 12 in cutting swath, which matches the narrowest swath on this page. That means more passes on a big lawn. It weighs 5.27 lb, so it is easy to swing around fences, trees, and garden beds.

Cutting speed is listed at 9000 RPM with an auto-feed head. The listing says the line advances 0.4 to 0.5 in at startup, so you do not bump the head. You do need to pull the line out to 6 in before first use. It also converts to an edger for lawn edges.

It runs on two 2.0Ah batteries, and the listing gives about 15-20 minutes of runtime per charge. That is short, so the second battery matters. The maker doesn't publish battery energy in Wh or a warranty length. Impact-resistant goggles are in the box. Plan around two short sessions rather than one long one. Best for small yards and light work.

At 3.28 lb the ALSO GO is the lightest of the 17 products that list weight. Light weight cuts arm fatigue on long sessions and helps on slopes and tight corners. It ranks fourth on our list. Its 24 V system carries a 96 Wh battery, and the listing says the kit includes two 4.0Ah batteries and a quick charger.

No-load speed is 11000 RPM, well above the 6200 RPM low on this page. The listing describes a 5-in-1 tool that converts to a string trimmer, edger, and bush cutter, with an adjustable shaft from 33 to 47 in and an angled head. Assorted blades are included for heavier brush.

Fit is the catch. The maker doesn't publish a cutting swath, line diameter, line feed type, or warranty length. Because it leans toward blades, it suits a buyer who wants one light tool for weeds and brush more than a classic line trimmer for fine lawn edges.

The BLACK+DECKER LST136 ranks fifth. It runs on 40 V and cuts a 13 in swath, wider than the 12 in models at the low end of the list. A wider swath means fewer passes. At 7.8 lb it is heavier than the EGO at 7.4 lb and the HortiHub at 5.27 lb.

A PowerCommand dial lets you choose maximum power for thick weeds or maximum runtime for longer jobs. That is useful because the maker doesn't publish a runtime figure. The auto feed spool releases line as needed, so you do not bump the head. Top speed with no load is 8500 RPM.

It converts from trimmer to edger, and the listing says that takes seconds. The battery has a state of charge indicator, and the included fast charger restores a full charge in 2 hours or less. Battery energy, line diameter, and warranty length are not listed, so ask the maker for those before buying.
