Combines 630 Hydraflex grain head

I'd check with WA Johnson Mfg. They make a replacement "smooth floor" for the JD Hydraflex. I have seen it Farm Shows, but it is not shown on their web site. http:__www.wajohnson.com_ W.A.

Just find a 630 head without the stone dam. John Deere made it both ways with and without.

Not exactly. They make a 2" dam and a 1" dam. Also, don't get an SCH. It won't work...rakes.
