PROFESSIONAL BRUSHCUTTER WITH ECOSPEED
The STIHL FSA 90 R battery brushcutter offers high performance and high efficiency for yard and landscape maintenance professionals. The loop handle gives you the greatest possible scope to manoeuvre when mowing between trees and shrubs and in other tight spaces. Thanks to the STIHL ECOSPEED partial load function, you can set the speed directly on the control handle. If you do not need to work at full speed, you can reduce it. This lowers noise emissions, the risk of stones or other hard objects being flung around, and also energy consumption. You can work without ear protection even at full speed, thanks to the quiet EC motor. That means you can work efficiently even in noise-sensitive areas such as near schools, or in hospitals or city parks.
This battery brushcutter is equipped with a STIHL AutoCut 25-2 mowing head as standard. The spacer bracket helps protect trees and other plants from unwanted damage as you work. A double shoulder harness is supplied as standard. This facilitates ergonomic working even on large-scale jobs. The practical carrying ring helps you store the STIHL FSA 90 R.
STIHL recommends using a round, quiet mowing line for battery brushcutters with a line mowing head. This not only reduces noise pollution as you work, but has also proven to be more efficient in tests. Compared to a round mowing line, battery life with this type is up to 10% longer with the same cutting performance. That’s why STIHL battery brushcutters with line mowing heads come with a round and quiet mowing line as standard.

All battery power tools within the STIHL AP-System have been designed for professional use and daily application, including in adverse weather conditions. With that in mind they are certified as splashproof; the effectiveness of this is also verified through demanding internal checks. The splashwater test meets the IPX4 standard, among others. |
