F2 Chart for settings in using a spike cylinder in wheat

Ive looked at the operators manual to see how to center the spikes on the concave door, and it refers to the closeness of the teeth to the floor of the concave. But I havent found a chart like the one for the rasp cylinder, with settings for distance from the concave, speed of the cylinder for wheat, etc.

Anybody know those sorts of things?

I can not help you with the Gleaner F, but can share with you some information from the J.I.Case manual and experience gained in operating a
spike-toothed combine. Your cylinder speed will be similar to those used with rasp bar cylinder. The number of rows of spikes installed is the
major influence on threshing efficiency. Too many and you will be over threshing, too few and grain will be left in the heads. Having the teeth
centered and straight is very important. Your cylinder should barely clear the concaves. The only exception to this would be in very dry legume
crops when it might be necessary to increase the clearance to avoid excessive splits. That would only be after removing all but 2 rows of spikes
and slowing the cylinder speed. For wheat, you will likely need a cylinder speed of 14-1600 rpm and all the rows of spikes in. The Case could
have 6 rows of concave spikes, but I don't know how many the Gleaner could take. At one time here, many farmers switched their cylinders and
concaves back and forth depending which crop they were harvesting. The spike will thresh tougher straw than a rasp and will produce a better
grain sample, if set correctly.
