Tune in to this extreme and crazy durability test of the STIHL FS 91 weed trimmer as Stu & Chip put it to the most gnarly and unforgiving tests! Join us as we drag the STIHL FS 91 through dirt and water, as we bump it over 5000 times on to plain old concrete, as we sink it all the way into a lake, and even throw it up to 30 feet in the air on an empty parking lot.
