Segmented crop processor roll for forage harvester

A forage harvester comprising in combination

• a main frame supported on ground engaging wheels,
• a header mounted on and extending forwardly from said main frame,
• a cutting assembly comprising a cylindrical cutterhead including a plurality of knives having cutting edges rotating in a cylindrical path, and a shearbar operatively associated with said knives for chopping crop material,
• feed means for receiving crop material from said header and conveying it to said cutting assembly,
• a discharge assembly located on said main frame, said discharge assembly including an inlet for receiving crop material and an outlet for discharging chopped crop material via a spout to a collecting receptacle,
• a crop processor assembly comprising a pair of crushing rolls for crushing chopped crop material received from said cutting assembly and expelling it along a path to said inlet,
• at least one of said pair of crushing rolls comprise a continuous shaft, and
• a plurality of cylindrically shaped segments mounted on said shaft, at least two of said plurality of cylindrically shaped segments are interchangeable,
• said segments each having a fluted outer surface, the fluted outer surface of each of said plurality of said cylindrically shaped segments being contiguous with the fluted outer surface of the adjacent segment,
• each of said cylindrically shaped segments comprise an integral mounting hub having a centrally located bore for operatively receiving said shaft, said hub coaxial with said fluted surface and said shaft, and wherein said fluted surface of each of said cylindrically shaped segments extends in an axial direction along said shaft a distance greater than the distance said integral mounting hub extends along said shaft.
