JD 9500/9510 Conversion To Rice

Hello All,
First post here. Been scouring the internet for a couple of weeks now to try to get an answer to this question. I need to find out what I need to do to convert the JD 9500/9510 corn/bean to make it eat rice. I have been tasked with this. We will be purchasing these machines in the US and shipping them over here to Asia. From what I gather we need to change the cylinder to a spike tooth cylinder and the concave to a spike tooth concave. Past that I haven't been able to find what else needs to be done to make these machines eat rice and do a fair job of it. Also, would the machine setup be as it is in the manual, or would that change with these mods in place. These machines will only be eating with 15 to 18 foot heads, probably 15 foot.

Anyway, I sent emails to John Deere trying to find the answer to these questions and surprise surprise no replies!! I did find that they use or have used in the past JD9500's to eat rice in Australasia but the machine had a "Rice Package" in it?? For the life of me I can't find what this "Rice Package" consists of for the JD9500.

Thanks and any info would be greatly appreciated. If someone wants to converse by email I will gladly pass it along. I really would like to find a definitive answer. Something like "Change this this this this and this and then make it eat rice, if it doesn't eat well adjust this and this and let it eat again. I forgot to mention I grew up in a small farming town in Nebraska, but have never farmed nor played with a combine. I've been known to turn a wrench or two though

Thanks bunches more

Hmm, there are lots of second hand John Deere rice machines and other brands sitting in dealer yards here in Southern NSW eg Finley or Grifith. They presumably are all set up to work straight away and Australia is a lot closer to Asia.
Rice package mentioned would include stainless steel internal components plus a few other things I am not aware of

A few changes I know about:
1) Spike tooth rotor and concave
2) drive for above
3) beater speed pulleys & belt
4) correct chaffer (not deep tooth)

The only reason I know of the above, is I converted a 7720 "the other way".

Your best bet is probably to go to the JDParts website, put in 9500 as the model, and do some studying. It will require some time on your part, but you can often find "options" listed for "rice", "wheat", etc. The only other source would be the actual combine manual (how to set for rice) and if you can find a dealer used to selling/servicing rice combines (deep south).

Thanks Jeff & Rice Cocky
Well that's a start. My first choice was the CTS or CTSII machines. All I have read about them says they eat rice well. Parts will soon become a problem with those because they don't make them anymore. There is only 3 of them for sale on Machinery Pete's site as well. So, I don't know if that's a good sign or bad sign. The STS models are a bit out of our price range unless they have upwards of 6 thousand hours. I want to stay away from machines that have only had rice for their dinner I have seen many people say that a 2000 hour rice machine is pretty much ready for the scrap yard.

Thanks Jeff, I'll check into those things you listed. "Spike tooth Rotor"?? Did you mean "Spike tooth Cylinder"?? I have checked the prices on Spike tooth Cylinder and concave and it's doable. I'll have a look at the prices of the other stuff you listed. I have read the spike tooth cylinder and concave are a must or pretty close to a "must" for these things to eat their rice meals a bit better.

The JD 9500/10's are listed in "The Rice Harvesters Reference" as being a "rice machine" That's an Australasia publication I am pretty sure.

I figure if we can just change a few things to get them to eat rice reasonably well, that would be good for a start. Then after that change stuff as it wears out. Maybe not thinking correct on that?

Also, I just got an email from Deere. What a surprise, but all it said was, "check with your local dealer" and "good luck" very kind of them to send such a helpful email(sarc.)

Thanks Jeff & Rice Cocky for the replies. I'll keep researching this.
