The STIHL FS 240 R professional trimmer combines a heavy-duty design with the versatility needed to handle a variety of challenging clearing situations. Providing 20% more fuel efficiency compared to the previous model, the low exhaust emission engine, combined with the large (25.4 oz.) fuel tank, means youll spend more time cutting and less time refueling. The FS 240 R is an ideal addition to any professional crew charged with cutting around ponds, along canals, in roadside ditches, and through heavy thickets.
