Powerful and light

Gtech’s new Grass Trimmer uses a high performance 18V motor, giving you the power to cut and edge the lawn – without a cord to hold you back. But the main thing you will notice is the weight. At only 1.75kg, the ST20 electric trimmer is incredibly easy to manoeuvre, putting less strain on your arms and back.

Practical and easy

Designed for comfort and ease of use, the Gtech Cordless Grass Trimmer features an adjustable handle for perfect balance. Equipped with a one-handed power trigger and safety switch to prevent accidental starting, it is simple to operate.


With a twist of the cutting head, the Gtech Grass Trimmer easily converts to a precision lawn edger, allowing you to give your lawn a neat finish.

30 minute run-time
Long run-time

The grass trimmer mechanism is powered by a Lithium-ion battery, giving you up to 30 minutes run-time with a charge time of just 4 hours.
