As a professional, your time is valuable. The STIHL FS 70 R grass trimmer understands that. It features a powerful and fuel-efficient engine, which means longer run times and fewer refuels. The FS 70 R is also powerful (more powerful than the FS 56 RC-E) and makes quick work of your daily landscaping tasks. Need more line? Just tap the cutting head on the ground and watch as its AutoCut head automatically feeds out new line. This trimmer is also built to last, featuring a sturdy cable drive shaft, a high-durability, forged connecting rod, and a four-bearing gearbox. As a bonus, it is all backed by a rock-solid, two-year limited warranty.
