I recently bought a o6 challenger 670, same as 9790 MF, what are the pros and cons compared to the R62 that I have been running. What is the best way to replace the cover over threshing part of rotor, do I have to remove rotor? Which concave are best in soybeans.

If I understand your 1st question correctly the answer is yes. We have Gleaner A75 and it is the same as 670. It looks impossible to find room to work from top. As to your 2nd question..is it a corn/soybean machine? If it is, then the concave that is in it will work fine. If it is a wheat machine then you need to ask harsh!
