Common questions

Questions before you buy

What counts as a heavy-duty cordless strimmer?

Look for a higher-voltage system, a wide cutting circle and an attachment suited to the material. A line trimmer remains intended for grass and weeds; use a brushcutter configuration only where the manufacturer permits it.

Is a cordless strimmer powerful enough for long grass?

A capable model can cut long grass in manageable passes, but dense or woody growth may need a brushcutter. Check the permitted attachment, line specification and battery runtime in the manual.

How wide should a heavy-duty grass trimmer cut?

Wider cutting circles cover open ground faster, while smaller heads are easier to guide around obstacles. The models here specify cutting widths from 26 cm to 380 mm.

Do heavy-duty cordless strimmers include batteries?

Package contents vary. DEWALT DCMST561P1-GB is sold with a 5 Ah battery and charger; check the exact STIHL or Einhell listing because tool-only variants exist.
