I run a late model 1440 which should be comparable to an early 1640. My grain table is a 1020 15' and corn head is a 6 row 963. No problem in 70-80 bu wheat running 3 MPH. As long as soybeans are dry, I also run 3 MPH in 40 bu beans. Although I just started corn, which I'm guessing to be over 150_A, I am down to around 2 MPH. Hope this helps!
