Good to know - This Gtech grass trimmer has a 23 cm cutting width, so you can trim big patches all at once - It's cordless meaning you can cut grass and weeds with no cable in your way - The 18 V battery gives you up to 30 minutes of runtime to get the job done in one go - With a swivel head, you can easily change between trimming and edging - Just press the safety switch so it won't accidentally start when you're not ready
