Combines long Straight Rotor Bar Design

[Harvester]

No, not in the case of the Massey. The shorter, segmented and staggered rasp bar design that you see Case and JD use provide greater agitation of the crop mat compared to a continuous long bar design on those machines, enhancing separation. In the case of the Massey, the long continuous bar would seem to provide better threshing performance than a staggered configuration, which the JD and Case Specialty rotor can struggle with, and the Massey uses the rotor knives to provide the advantages of crop agitation_separation, so the MF actually would seem to have the best of both worlds.

not correct! Saint John Welding has been installing the same bars on case, nh and massey rotors since 1997. gleaner stole thsi design.

Gleaner is still using the long continuous bar design, just like the Massey. Obviously St. Johns Welding has made a good name for aftermarket rotors installed in the combines you mentioned above; I was merely talking about O.E.M. applications.
