4 mph in both wheat and beans isn't out of line for the yields you mentioned. Corn at just about any speed you want.

Combines Speed with a 2188 in 40 bpa beansIJ

In my experience with soybeans, speed is usually determined by the ground conditions and the amount of stalk rather than yeild. For example, we are cutting 60 bu row soybeans at 5.5 mph with a 2388 with 25' MacDon right now. In drilled soybeans of similar yeild, we may be more in the 4.5 - 5 mph range. If their are a lot of green stalks or the beans are lodged, it may be more like 3.5. The McDon has added at least one half mph to our speed, maybe more. No slugging to worry about. But we cut a lot of acres at 4.5 mph last year with a 25' 1020. No reason you couldn't do 4 or better with a 30' 1020.

The MacDon is a draper head. MacDon makes the Case 1052 for them. It will cut close to the ground but not quite as close as a flex head. It does not flex or have header control. But it is mounted on springs that allow the whole header to float on the ground, both side to side and up and down. The main advantage of the header is that it feeds perfectly, we were cutting down beans today at 5 mph. There is no slug feeding or auger choking up. I've also noticed that you don't have to use nearly as much reel, since as soon as the beans fall off the cutterbar, they are taken away by the belts. We don't shatter nearly as many beans with the reel. The MacDon runs the cutterbar much faster than the 1020, something like 1200 rpm. I think the 1020 is 600 standard. We changed pulleys on our 1020 to speed up the cutterbar so we could cut faster. You can get different pulleys from your dealer.
