I was the one there. No, this was not a yield monitor reading, I was watching the trucks load and leave the field. I made some posts about it back when it happened, too. The fall of 2001, near Pratt, KS. What I timed within the hour, was 4 full trucks that left. You have to consider yet, there was still a full hopper on the machine, one in the cart not filled, the other cart already full and now unloading into the semi, so I figure at least 2 combine loads there or 600 bushels. I only rode the combine 2 hours, then had to let others have their turn to ride. I did time the loads with my own watch, so I know I must be very close with these figures. Again, it was a 12-row head, traveling at a steady 5.5 MPH. The owner told me his yield stood around 235-240 bpa. Back when I first mentioned this at the time it happened, nobody here ever challenged it. The owner did have his own semis plus at least 3 more hired. It sure helped to have his own granery only a few miles away, but the truckers all said they had no time to rest between loads,either. As to the biggest lexion with a 16-row head, my gues in the same field, would probably add at least another 1,500 or more bu_hr to that figure. Does that make senseIJ I know the biggest lex [Model 590] is larger than the 9750, at least in terms of capacity. If you want to talk to me more about it, please e-mail me [sun_dog63[at]yahoo.com] and I would be happy to ink you directly to the owner_operator of this 9750. He may have a lot more folow-up info, as I haven't been there, now, for over 4 years.
