PETE, a suggestion to help the green stem _ green material rumble problem. The rumble is probably caused by a rolling or balling of green material as it moves through between the thresher bars and the concave and maybe the separator cage as well. In our long past N7 we installed strips of 3 mm [ 1_8" ] flat under the flat helicals. The strips were wide enough so that around a 1_2" of flat extended out from under the helicals on the live side of the helicals. This provided a smooth corner against the live side of the helicals so that material could slide along the helical without getting snagged in the cage holes and stalling which we believed led to balling and rolling of tough material and therefore rumbling. It certainly made a big difference to the operation of the N7 in tough green material which was the achilles heel of our machine and was traumatizing to try and operate due to the banging and crashing when green material went through.
