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 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. The trimmer is also built to last, featuring a durable cable drive shaft, a high-durability, forged connecting rod and a 4-bearing gearbox. And it’s all backed by a rock-solid two-year limited warranty.
