Ive asked these questions on other forums but without any response so if anyone can add to this issue please do,,,
All 9600s that ive ran over the years including my 50 walker machine, in dry heavy yielding wheat, on many occasions have plugged above the precleaner under the walkers,before the shaker pan, behind the concave, SOLID. I have yet to figure out what causes this, i have a few ideas, and have a few ideas on how to fix the problem but need some other input.
First question Does this sound familiar?
Our yields here reach 4+ tons to the acre which contributes to the extra chaff load.
I have removed the walker curtains to keep any unwanted material from hitting the shaker pan and returning to this problem area.
I run slow cylinder speeds to the point in which I do not over thresh the straw. It exits seperator full length and sometimes with the squiggly (so my Dad calls it) intact.
Even though the JD operator book says to run precleaner closed we run ours open just a touch to take seed earlier in theseheavy yields, but never open enough to effect the tank sample. What a difference it made on the day I did decide to run the precleaner open.
My thoughts on how to maybe fix the problem not using more than one method at a time are:
More air to convey the material out of problem area quicker?
Close precleaner to try not to deflect chaff upwards?
Less air to stop chaff from blowing too far up towards pan and walkers?
Louvering pan bottom to allow for excess material off walkers to sift over chaffer area rather than all the way to front precleaner?
Extending front pan edge?
Shortening pan Edge?
Removing Fan jackshaft shield in front of pan?
Different preclener element?
Too much header?
This mystery plugging area has worried me for several years but now Im ready to start modifying my machine to make it stop. I know other 9600 guys who have seen this when running 30ft and larger heads. Im looking for serious responses only and preferably from those who have seen this happen first hand and who knows exactly the conditions on the machine and crop at the time of incident.
Thanks to All.
