Common questions

Questions before you buy

What does 3-in-1 mean on a cordless grass trimmer?

It varies by model. Manufacturers may mean trimming, edging and a mowing mode, so check the model page and manual for the functions included.

Can a cordless trimmer edge a lawn?

Some models convert to edging by rotating the head or using an edging wheel. WORX describes WG184 as switching between trimming and wheeled edging.

Does the WORX WG184 have a mower mode?

No. WORX states that WG184 converts between string trimming and edging and does not have a mini-mower mode.

Should I buy a bare tool or a kit?

Choose a kit if you need its matching battery and charger. A bare tool may suit you if the manufacturer confirms compatibility with a battery you already own.
