Cordless String Trimmer/Edger Combo Tools Explained

Combo tools either reposition the line head for edging or accept a dedicated edger attachment. The right choice depends on border length, yard size and the battery system you own.

A cordless string trimmer/edger can cover two lawn tasks with one battery platform, but “combo” describes more than one design. Greenworks' 40V 13-inch model uses a rotating shaft and edging wheel; other systems, such as Milwaukee QUIK-LOK or compatible DEWALT attachments, use a separate edger attachment on a power head.

Common questions

Questions before you buy

What is a cordless string trimmer/edger?

It is a battery-powered line trimmer that can also cut a lawn border, either by changing the head position or by adding a compatible edger attachment. The product description should specify which design it uses.

Is a rotating-head trimmer the same as an attachment-capable trimmer?

No. A rotating-head model changes the orientation of the trimmer itself, often using a wheel for guidance. An attachment-capable system uses a separate edger accessory fitted to its power head.

Does Greenworks make a 12-inch 24V cordless trimmer/edger?

Greenworks' product range includes multiple trimmer/edger configurations, but verify the exact 12-inch 24V model in its current official catalog before selecting a battery or accessory. This guide's confirmed example is its 40V 13-inch Gen 2 tool.

Are batteries included with combo string trimmers?

Some combinations are kits and others are tool-only. The Greenworks 40V 13-inch Gen 2 page cited here is tool-only; check the precise product code for other brands.

Can I use a trimmer/edger on every lawn border?

It can maintain many grass edges, but the manual sets the permitted operating position and surface conditions. Use the guard and wheel as designed, and avoid striking concrete or obstacles with the line head.
