摘要：
A helical-bladed cutting reel includes a central shaft having a central axisof rotation, and a plurality of helical blades.Each of the blades extends along a respective helical path on an outer surfaceof the central shaft. A direction of each respective helicalpath has both an axial component and a circumferential component relative tothe central axis of the central shaft as it extends acrossthe outer surface of the central shaft. Each of the helical blades is weldeddirectly to the central shaft. In preferred embodiments all ofthe blades are continuously autogenously welded directly to the central shaft.
