yes at the University of Nebraska Panhandle Research Station (Bean Day) in August. Pickett had one mounted on a JD(9600IJIJ) Didn't see it work, just saw it mounted.
we have a local machine shop that has done the conversion on a few 9600 and i seen one done a 760 also.a local guy says to me for $10 000 he can permanently install one on our R5.the unloading should be faster and less agressive on edible beans. P.S the funds are in canadian dollars
