Best Cordless String Trimmers for Canadian Yards (2026)

The DEWALT DCST925M1 is a balanced kit for regular home trimming; choose the RYOBI 40V HP kit for a wider cut and heavier growth, or STIHL for a compact yard.

Quick answer

For most home yards, the DEWALT DCST925M1 kit is a practical starting point: it includes a battery and charger and cuts a 13-inch swath. The RYOBI RY40HPST02K suits thicker growth and a 17-inch adjustable swath; STIHL FSA 57 Set is a lighter-duty AK-system alternative, while Greenworks 40V offers an attachment-capable kit.

Common questions

Questions before you buy

What is the difference between a cordless string trimmer and a cordless grass trimmer?

In Canadian product listings, these names often describe the same line-cutting lawn tool. Check the cutting head, line diameter and intended work rather than relying on the label.

Is a 20V cordless trimmer enough for a yard?

A 20V kit such as the DEWALT DCST925M1 provides a 13-inch swath and suits routine edge and grass maintenance. Dense weeds or a larger area may call for a wider head and a higher-capacity battery platform.

Can a cordless string trimmer use attachments?

Some can. DEWALT DCST972B and Greenworks 40V models list attachment capability; confirm compatibility with the exact attachment and power head before buying.

What line size should I use in a cordless grass trimmer?

Use the diameter specified for your exact head. The cited DEWALT DCST925M1 uses 0.080-inch line, while RYOBI RY40HPST02K lists 0.095-inch line; do not assume sizes interchange.
