Setting a 9500

[Trucker pete]

With the poor crop of corn to be harvested, Anybody have some pointers in setting a John Deere 9500 for cylinder speed, concave opening, fan speed , sevie and chaffer openings in wet, light corn this this fall?

Not 9500 specific, but a general rule of thumb...slower cylinder for dryer corn, smaller concave opening for smaller ears,lower fan speed for lighter kernels. I would leave the sieve and Schaffer set normal and then adjust as you go, dependent on the trash in the bin and in the return elevator.

Oh, and get a manual!

I have went by the manual played with it myself. Even made exact wooden gauges the set the chaffer and sieve and my experience has been if it has green paint it is going to throw some out the back

You will set it like any other year. The first thing is to get a solid cob without splitting it. So tighten down until the cob is split and then slowly open the concave up until the cob is hole. Then slow the cylinder speed down until your leaving some corn on the cob. Slowly speed it back up until you have a clean cob. (Hint on the JD 9000 series combines. They will eat corn. so you will need to go faster in this lower yielding corn to get a good job thrashing the kernels off the cob. If your having trouble splitting cobs open the cylinder up and increase ground speed. This will often clean up the splitting issue. Keeping the cylinder full will make it clean the grain better without damaging it. As for the chaffer, sieve, and pre-cleaner. Set the pre-cleaner first. Open is about 2-3 turns to start. Then slowly open it until you have some chaff and such in the bin. close it back until your only getting clean grain in the bin. Then open the chaffer until there is little corn reaching the back. On the sieve just set it to where there is little grain going up the return elevator. On fan speed I usually start it at about 80% of full speed. You need to keep everything floating on the chaffer. Then do a power shut down of the separator. This stops the grain where it is at. Look at where your have corn and you do not have it. Any grain in the walker area usually means to high of cylinder speed or leaving grain on the cob that gets carried over. chaffer and sieve are self explanatory.

P.S. This harvest will be one that you need good cylinder bars and a good concave. If either are worn or out of level you will struggle getting the corn off the cob with out grinding the cob or corn.

Not by an operator that knows how to set a combine. However, if you set a 9000 series walker combine by the book you will not do as good of a job as the combine is capable of.

I start with the book settings and run from there. I find I usually am fiddling with fan speed the most as the crop changes. I think new combines with all of the different settings are harder to dial in than our old ones from the 60?s. She will pull a decent sample with some adjusting but I?ve never been as proud of he 9500 sample as I was our old Massey super 92.
