The edger is essential for all those hard-to-reach places in the garden. It clears grass around trees, along paths, around lawns and flowerbeds, and on embankments. An edger usually has two handles. The first is a control handle and the second is a holding handle. The Stihl FS 38 is based on this model and we will give our opinion after testing it. However, you can hold a trimmer with one hand, and it has a cutting head and a protective guard that keeps grass, rocks and gravel from flying around. The FS 38 from STIHL is lightweight and easy to use. It’s one of the most popular garden products in Stihl’s line of edging tools.

You can also learn more about how to operate and use an edger if you haven’t purchased one yet.

Notre avis


This gardening tool is equipped with a powerful 27.2 cc engine and a decent fuel tank capacity. Its characteristics allow you to use this trimmer to weed for a while before having to refill it. Of course everything depends on its use, if the work is intensive or not, the surface of your ground and green space…


Notre avis


The Stihl FS 38 thermal trimmer is the easiest way to do maintenance work and the easiest way to quickly cut grass in inaccessible or tight spaces. With its precision, you won’t over-cut or damage your plants. Plus, it’s the cheapest and most environmentally friendly way to do yard work. If your budget allows, we have tested the Sthil FS 240 professional gasoline powered trimmer.

This thermal trimmer model has an extra-long cutting range of 380 mm – even in difficult soil conditions. It has an excellent cutting quality after several tests in our field.

On the attachment side, the FS 38 is equipped with an AutoCut C 6-2 mowing head, but these attachments are interchangeable. This head has a 14 mm spacing and a 16 mm side exit. This means there are more cuts per meter as well as less overlap of cuts, which helps reduce fuel consumption.

Ergonomics and safety

Notre avis


This versatile garden tool has a weight of 4.2 kilograms, which is relatively much lighter but still robust enough. This weight can be compared to a thermal brushcutter like the Stihl FS 70 CE, which still weighs 8.4 kg. Indeed, having to use a very heavy gardening tool for many hours if you have large gardens can be tiring at the end of the day.

Safety has also been greatly improved with the addition of a double starting trigger, so you can’t accidentally start it and avoid any gardening accidents. But it is important to wear closed shoes, protective glasses or visor and well-fitting clothes.

As an added benefit, a protective case protects the trimmer from splashes and dirt while giving users a clear view of the cutting tool.
