Stihl Weed Whacker Review
What happens here
Start the Stihl FS 90 R. The creator demonstrates the starting procedure: setting to 'start,' pulling the cord until it 'kicks,' then turning the choke off and pulling again. The machine starts easily on the second pull. He then uses it to trim dense, waist-high grass and weeds along a gravel road. While the FS 90 R cuts, it noticeably bogs down and slows when encountering very thick patches, requiring extra effort to maintain cutting speed. The creator points out that the factory-installed string (Stihl CF3 Pro 1.05) is inferior and breaks easily, exacerbating the performance issues.
Goal: Showcase the Stihl FS 90 R's cutting capability and limitations in heavy growth.
