Isn't that the truth. That is probably asking the impossible! Our farm engineering team spends a week correcting layout of electrical, hydraulic, and fuel line issues. (Thanks Lee and Garrett.) Several have been the same through several models. I remember the old days when they had a "plant pal" assigned to each new combine sale who would call and check with the owner and see how things were going and if there were any issues. It stopped probably because it broke union protocol of a union member talking directly to a farmer of what the problems are. We haven't even had a combine school for a few years. Our territory rep has been around a few years. I think he replaced Kevin Bien though when he was the rep in our area a long time ago. Yes the good old days.IMO in my conditions I feel they have got the workings pretty bloody good . It's probably things like making the engine bay tidier, making air cleaners , dipsticks and oil tanks better positioned. Stop yield monitor leaking grain. Having cruise control work of engine load instead of speed. Etc. Etc.
