The GT50 is a lightweight blade trimmer for lawn finishing; its 23 cm cutting width and 18V battery are the key specifications to weigh.

The Gtech GT50 cordless grass trimmer is designed around quick lawn finishing: Gtech specifies an 18V lithium-ion battery, a 23 cm blade cutting width and a swivel head for switching between trimming and edging.
