Notre avis

First of all, the FS 55 is compact with a weight of 4.9 kilograms, which allows you to easily access all those difficult areas and corners, even on steep and rugged terrain. Secondly, it is also equipped with a single handle system for easier handling with a good grip and maneuverable guidance when working at height or on the ground, such as for paths or the edges of your lawn.


Notre avis


It is also equipped with a grass trimmer head: 8-tooth grass knife (these accessories are interchangeable) for denser vegetation and intensive and efficient work without any damping (for example: mowing a dense grass meadow). Moreover, the diameter with the cutting heads is 380 mm with a wire and 280 mm with knives. However, despite its characteristics, it is not sufficient to cut dense shrubs compared to certain models of other brands. In addition, an ergonomic handle makes the tool comfortable to handle without too much effort.


Notre avis


Stihl has put all its know-how into this gas-powered model with a stratified two-stroke engine of the latest generation, with a displacement of 27.2 cm³ and a noise level of 94 decibels, which is not quiet. Let us mention that this powerful engine guarantees optimal performance and a lot of power, while saving up to 20% of fuel for a similar thermal motorization. A simple thumb press is enough to start the Stihl FS 55, in short, ignition is no longer a problem. On the other hand, we regret the absence of an anti-vibration system which slightly detracts from its ergonomics.


Notre avis


Then, in terms of autonomy, it is equipped with a 0.33-liter fuel tank, which seems correct for garden tools in this range.

To conclude, as with any gas-powered garden tool, it is important to clean and regularly maintain your garden equipment after each use to maximize its lifespan, especially in case of intensive use. Without mentioning safety, it is necessary to wear the appropriate protective equipment: safety glasses or visor, helmet.
