Gtech-GT 3.0-Grass-Trimmer-Review

The fact is that you need a lawnmower for a large size garden, but whether your yard is small or large, you need a grass trimmer to keep your lawn in perfect condition at all times. You may have the best lawnmower, but it still won’t cut around fences, tree trunks, walls, and other vertical objects. 

This is where the Gtech GT 3.0 grass trimmer proves handy, as it allows you to cut the grass around hard to reach areas without being bogged down by pesky wires. And if you’re thinking that battery-powered tools are weak when it comes to performance, the Gtech GT 3.0 grass trimmer is bound to change your mind from the first time you use it. 

Who is the Gtech GT 3.0 Grass Trimmer for?  

The Gtech GT 3.0 grass trimmer sometimes dubbed a string trimmer uses a replaceable plastic blade rather than a string to cut grass. If you have areas in your garden that mowers can’t reach such as around the edges of the lawn or under a hedge, then the Gtech GT 3.0 grass trimmer is perhaps the tool you need. 

The Gtech GT 3.0 grass trimmer is a solid improvement over its much successful predecessor – the HT20. It shares several common traits in terms of design and functionality with the older model, but has also been greatly improved and upgraded in many key areas including longer run time, and a more durable blade. 

Just like the previous model, the Gtech GT 3.0 grass trimmer features a lightweight design, and is comfortable to hold, making it a joy to use even across extended periods. One of the noteworthy features of the Gtech GT 3.0 grass trimmer is its 180 degree turning head, which allows you to easily switch from flat cutting to edge trimming.
