Best 20 Inch Cordless Hedge Trimmers (2026)

Greenworks pairs a brushless motor with 20 inch dual action blades running at 4000 strokes per minute, and states a 1.1 inch cutting capacity. Higher stroke rate means each tooth passes a branch more often, so cuts are cleaner and the trimmer is less likely to snag and stall. A debris collector sweeps clippings off the top of the hedge as you go, which saves a cleanup pass.

That 1.1 inch figure is well above the 3/4 inch of the Craftsman and SEESII, and almost double the 3/5 inch of the VIVOSUN and Endutools. Up to 65 minutes from a 2.0 Ah pack reflects the efficiency of the brushless motor. The 24V platform is smaller than V20 or 20V MAX, so check which other tools you want on it.

Keep the blades clean and oiled, because sap buildup increases friction and runtime drops. A brushless motor needs no brush service, so the blade is the main wear part.

The CMCHT810 is a straightforward brushed motor trimmer with 20 inch dual action blades and a 3/4 inch cutting capacity. The full wraparound front handle lets you hold it comfortably whether you are cutting the side of a hedge vertically or the top horizontally. It is sold as a kit with a 1.5 Ah V20 battery and as a bare tool, which is the identical trimmer without a pack.

Compared with the Greenworks at 1.1 inch capacity and 4000 SPM, it is less capable on thick wood, but it shares batteries with the large Craftsman V20 line. If you already own V20 packs, buy the bare tool. The 1.5 Ah kit battery is small, so a larger pack makes a noticeable difference.

Craftsman parts and service are easy to find in big box stores. Oil the blade after use and hang it on its hook to keep the teeth off the floor.

SEESII bundles two 4.0 Ah batteries with a 20 inch dual action trimmer, which is far more stored energy than any other kit here. The rear handle rotates 180 degrees, so the trigger stays comfortable while the blade is vertical for side cuts. A protective tip guards against striking walls and fences.

Capacity is 3/4 inch, matching the Craftsman, and you get roughly five times the battery of the Craftsman's 1.5 Ah kit. It is the best choice for long hedge rows where you do not want to stop. The tradeoff is an off brand battery system with no other major tools.

Rotating handles have a latch; keep it clean so it locks firmly. Oil the blades and store batteries indoors over winter.

The DGQHME uses SK5 steel blades, a high carbon tool steel that holds an edge well after hardening and tempering. It comes with two 3.0 Ah batteries rated for up to 60 minutes of trimming, and an LED gauge shows remaining charge. Cutting capacity is 3/4 inch.

It sits between the SEESII and the VIVOSUN: less battery than the SEESII's two 4.0 Ah packs, but more than the single 2.0 Ah VIVOSUN and with a larger 3/4 inch capacity. SK5 steel is harder but can rust if left wet, so wipe it dry.

Apply light oil after each use and before storage. A sharp, oiled blade reduces motor load and stretches runtime.

Endutools fits a rear handle that rotates 135 degrees each way, the most adjustment in this group, so you can keep a natural grip on hedge sides, tops and odd angles. Blades are hardened 65Mn spring steel at 2700 strokes per minute with a 3/5 inch capacity.

At 2700 SPM it is slower than the Greenworks at 4000, so thicker stems are more likely to bind, and 3/5 inch is the smallest capacity class here alongside the VIVOSUN. It is best for regular light maintenance trims on established hedges.

The batteries are a 21V label on what is effectively an 18V class pack. Keep the rotation joint free of clippings so it locks securely.

The VIVOSUN is a simple 20V trimmer with laser cut dual action blades, a 3/5 inch capacity and a stated 1400 RPM no load motor speed. It includes a single 2.0 Ah battery and charger.

It is the lightest duty tool here. Against the Greenworks at 1.1 inch capacity, it handles only young, soft growth. For a few boxwoods or a short privet row trimmed regularly, that is enough, and it is easy to handle.

Trim often so stems never get thick, which keeps a light trimmer effective. Oil the blade and store the battery indoors.
