Cordless Trimmer Stihl FSA 90 R

The FSA 90 R from Stihl is a powerful battery brushcutter for mowing tough grass. With a cutting circle of 38 cm (mower head autocut 25-2) you can quickly handle large surfaces. The handle has a round handle, an operation with ECOSPEED function and comes standard with a single carrying strap. Usually you don't need hearing protection with the FSA 90R. The FSA90R cuts through grass, weeds and nettles like butter. When I started mowing small bamboo, I did use hearing protection (see video below).

Extra grass cutting blade 230mm

This was because there were a lot of dried leaves between the bamboo. I will soon be purchasing an extra 230mm blade, especially for grass, for mowing small bamboo and brambles. It just went well with the nylon thread, but it did cost me some extra thread on the autocut 25-2.

The FSA 90 R does not have a double handle, but a bow handle. It makes work in small narrow spaces much easier. For example, think of surfaces between a hedge and the fence of the neighbours. My previous petrol brushcutter had a double wide handle and it was very difficult to maneuver in such places. The variant (FSA 90 R) with a bow handle is supplied with a single carrying strap, the double handle brushcutter is supplied with a double carrying strap. The weight of the battery trimmer is 2.8 kg. Including the AP300 battery, the FSA 90 R weighs 3.9 kg.

Battery AP300 from Stihl

The AP300 battery is recommended by Stihl. I measured the mowing time with the AP300 and came to exactly 35min mowing at full power. The charging time roughly corresponds to the mowing time if you use a fast charger. I have an AL300 (fast charger) and the battery was fully charged in 45 min. With 2 batteries you can mow non-stop for almost a whole day. The AL500 charges even faster and with the AP300S you have a little longer energy. Then the APXNUMXS might be a better combination to be able to work non-stop. The brushcutter is always sold WITHOUT battery and WITHOUT charger.
