I am running a jd9600 with 643 corn head and 925 platform with yields form 60-100bu wheat, 30-70bu beans and 150-250bu corn. Most of the ground is flat or gently rolling. As far as the straw its about 50/50.
We are not very big into this yet so we do local farmers and drive the combine from farm to farm. I would like to expand but not sure how big we want to get?
If you want to have straw to bale you want a walker machine. It will produce good baling straw almost all the time. The sts machines need perfect conditions to make good baling straw in low humidity climates.
For a used machine, that walker will cut for less cost per acre in repairs and fuel than the sts.
My 9650W would cut beans faster than my neighbors 9660 sts which was in the same field helping me. I don't know about corn, I never ran it. On milo, I know a 9660 sts is an underpowered POS, and is only about 3/4 the size of a 9650W.
I would go with the sts hand down. I upgraded from a 9600 to a 9760 and what a difference that made and I only cut corn with it. I dont know why I waited so long to upgrade its been great. We were cutting 250 - 300bu between 18 to 25 % moisture and only buring 1.5 gallons per acre and 12 gallons per hour. We almost doubled our capacity. Its been nice to not have to look at the same feild day after day like with the 9600. Go with the STS.
we went from a 9600 to a 9650sts and love that thing.... we increased grounnd speed in every crop, only problem with the rotories is that every morning you should losen and tighten your rotor, i donno that maby is just our combine tho
I have a question. We are trying a used 9650 sts because our 9500 lay down a week a go. I am getting quite attached to it. It needs some work. it has 1950 sep hrs on it. My question is will my 25' head be big enough to keep it full enough to thrash well in beans and wheat? red rotors have to be full to thrash well. Not sure if JD is the same. We have a 8 row corn head so it suits it well. Any other things I should check on it before I sign any papers? thanks
