Jim a R40 will most certainly handle a 6 row head. We have run 5 to 6 mph in good corn with our 438 head. You can starve a bird to death behind these machines. As far as beans, we have a 320 head on ours and it handles it OK (cleaning and grain loss were great). I'm working with Hyper and others now to increase the speed of harvest from 2.5 to about 5mph. Do not be scared of the machine it will surprise in corn.Read the information from Dan about tuff beans. If you are buying the machine from a dealer see if you can get them to do the mods they suggest below before you buy it.
