The shears have 360 degrees of rotation to provide maximum work with minimal carrier movement.
The Fecon Rotating Shear (FRS) gives excavator operators the advantage of 360° rotation of the tree shear. This allows more reach and access to trees with less repositioning of the machine. The single knife (FBS1400) and dual knife (FBS1200 or FBS1500) are both equipped with heavy-duty cylinders and rods to provide strong shearing action and faster cycle times. They also feature a frame fitted with adjustable AR400 steel knives allowing more trees to be grabbed with lower ground pressures. These shears are best suited for thinning and fuel reduction. The dual knife action feature provides a more positive cut while maintaining the tree central to the shear and carrier. There are four excavator tree shear models: FBS1200EXC, FBS1400EXC, FBS1500EXC, and the FBS1600EXC, each with varying cutting capacity diameters of 30, 36, 38 and 41 cm (12", 14", 15" and 16"). All four models are provided with the "H" style mounting bracket and bolt-on hanger bracket fit to the excavator. Each model is equipped with heavy-duty cylinders and rods to provide strong shearing action and faster cycle times. They also have a strong yet lightweight frame, fitted with adjustable AR400 steel knives to provide you with efficient cutting in a durable tree shear. Source
