Typically for grain heads/platforms you would be looking at the 200 series. Examples include the 213, 215, 216, 218, 220. The early ones had yellow reels and the later ones had black reels. As time went on they discontinued some widths. So, some widths were only yellow reels. I think you were cutting small grains so a rigid head might be satisfactory. Most in the Midwest were probably flex heads for cutting soybeans. It is nice if the flex part of the head is stainless steel. It doesn't rust so the crop always slides across it easily into the cross auger. Having the Dial-a-matic head allows you change the cutting height (three settings) from the cab console. There would be an electrical connection hooking the head to the combine. Having poly on the skid plates under the head helps alot when the soil might be sticky like when cutting soybeans. I prefer the plastic replacement reel fingers over the steel tines. If the head flexes, raising the sickle into the tine, it can easily break a sickle section. Also, watch that you don't get a hillside head. It would work, but you would either need to put the level land drive shafts in the head or put some short shafts between the combine drive shafts and the hillside shafts. The plastic replacement tines/fingers are available from aftermarket suppliers. I don't think you were interested in corn heads, but the corresponding corn heads would be the 444 for 4 -38" rows, 443 for 4 - 30" rows, 643 for 6 - 30" rows, 843 for 8 - 30" rows. The next series of grain heads/platforms will work on your 7700 as well. There maybe some modification needed for electical and hydraulic connections. They are still very expensive compared to the older heads.

I changed to a stainless steel seals and plastic flex tines this year and it"s a new head! Are the poly skid plates really that good too? Just don"t get the advantage?
