Does anyone run a 12 row head on a 9670? It is basically the same machine as the 9770 minus the horsepower. Dealer said it would handle one fine in corn but they will also tell you anything to make a sale.
We have several out with this combination and have no issues , just make sure the 9670 is a 12 row ready machine and not a 8row machine. Also I assume that the 612c is non-chopping????I don't think that would be a wise choice.With that in mind it will work very well for you.
deerefever it is a chopping corn head, do u think chiping it will be enough for horsepower to run it. if not is there any way to take out the fuel pump and get a little more power beyond a chip. I'm not worried about voiding a warrenty, so full steam ahead.
430u, I don't believe even with a chip the 9670 wouldn't be a good choice for a 612c chopping, how ever a regular 612c will be fine on a 9670sts.As far as 9670sts with h-duty reverser, there is really no reason a 12 row would cause any drive line issues, when proper belt adjustment is done.
I agree acleighton, back in 96 a couple of us switched over a 1243 cornhead to 16/22, rebuilt all the cases, new g.v.l plastic.We adjusted the variable belt using the alt. method, with no issues, what combine was it on do you ask????1990 9600 that was 12row ready. I had doubts at first ,but after 5 seasons running 4.5-5.5m.p.h in irrigated corn I believed !!.
