Combines 7720 ground speed

[greenstrat]

I have same heads on a 6620 and I run about 4.5 max in 55 bus. beans, any faster and the cut suffers. In same yeilding corn as yours I can run about 4 and any faster and I feel I have head loss issues. Unlike everyone else who runs way faster than me. GS

I wish I could run 3 mph in corn yielding 180 bu. How do you have your chaffer and lower sieve setIJIJ Do you run your fan speed as fast as it can be set. We get alot of whole corn over tailings at any speed over 2.5 mph.
