Rice is very hard on a combine...very abrasive. Also the drivelines take a lot of wear in that type of ground. I would venture to say most 7720 Rice specials are worn out. Converting a nice standard version to a rice machine would be difficult & costly. There are extra supports, etc welded into the frame for adjusting spike tooth clearance. You would have to cut these out of a donor junker and weld them in. And then swap over all the special parts.
Having said all that, I've never harvested rice, I have no idea how a standard cylinder machine would work. I do think the 7720 T2 was one of the best conventional combines made, as far as just working with minimal fuss.
What other John Deere model do you recommend me for rice harvesting, what do you think about john deere 9500?
Do you know someone that may give me support?
I moved this all over from the other post. Sorry, The sole knowledge I have on this is that I had to go the "other way"...and how beat up that combine was. 2500 hours (supposedly) and all the grain pans & augers were worn out, the driveline coupler splines shot, etc. Ran great after I got it rebuilt though!
I've never been a fan of the 9500 series, because they are harder to get set right in corn/beans. Other than that, they are a fine and very popular combine--many many still running. Also much nicer cab! I'd avoid the 89-90 models. I will say you can but a good 9500 for about the same money as a good 7720 T2 in my area....which may or may not tell you something? No idea how they perform in Rice.
