That's odd, I've run mine 5 years and the only time I ever had a problem was in extremly short wheat. The biggest problem with any late model combine used on a shelborne is you need a forty ft head to let the machine know it's actually doing something.
WE are using them in Il for early wheat harvest(20-25%). Then get double crop beans planted without having to deal with the stawbeing piled up etc.There are some different ways to set them up like for rice etc. Wear is kinda high though.I think they do an excellent job.
They will, however, pick up wheat and barley that is completely flat on the ground, at 3-6 mph. Also canola that has been scattered by wind can be harvested very nicely.
