Providing 20% more fuel efficiency, the low-exhaust-emission engine, combined with the large (25.4 oz.) fuel tank, means you’ll 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.
