What heads will fit a 7700?

Just acquired a 7700 Deere Combine, now have a C2 Gleaner with on clutch to get rid of if you are interested =) Put 2 new batteries in it and drove it home this evening (about 35 miles)

7700 has no head. Will be cutting wheat/barley with it. What heads should I be looking at?

What should I know about a 7700 Turbo, only other combine I've been around is that C2?
 
Put that AC head on the 7700.There have been lots of cases/examples here on YT about that very thing.8x20 AC on 95;JD grain on Case ;IH on JD;JD on IH....
 
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.
 
For a 7700, I'd get a 218 rigid head for wheat/barley. They can be had for less than $1000 around here. There's also the 100 series heads, but they don't have a wobble box. They usually sell for scrap, or get mounted for combine demo derbys The rigid head feeds better than a bolted-up flex head in small grains. If you're in really heavy wheat (80-100 bushel), you may need to get a smaller head or take less of a cut.
 
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?
 
Would it need much for adapter parts??? The head is probably the best thing on the old gleaner??
I've got two leads on heads, a guy that knows a guy who has one and a guy who knows where there used to be one that got parked he's going to check if it's still there. Not sure what model either of these heads might be, but if the one I got woudl work??? Free is about the only thing in my budget right now.
The 7700 was given to me, the guy said he'd tried for 3 years to sell it with no takers???
 
I really have no idea how hard or easy that particular conversion would be.Just look at it closely,and do some measureing.It may not work,but maybe it would.Just some "out of the box" thinking.
 
200 series and 900 series heads should fit. A 222 would be a nice fit. As mentioned earlier yellow reals are the early ones but if the bats were replaced you wouldn't be able to tell from that. If I'm remembering correctly there were two different augers put in those heads early or late. The big auger feeds better, I don't really know how to explain the difference without pics, which I don't have.
 
I'd go with a 900 series head. Just overall improvement compared to the 200 series. But whatever head you get, just make sure it's in decent shape. Heads that need "some" work usually make the pocketbook lighter.
