We rented a Bobcat cold planer 24" HF on a S300. When the mill head is engaged and the operator tries to adjust the depth controls it steals flow from the head to the point where the drum in dies in the cut. We are only cutting around 2" so its not a deep cut by any means. We have already switched loaders from the dealer and still no fix, so it must be in the attachment itself. The dealer also acknowledges that it is not operating correctly but the only option for today was switching out the loader..............anyone have any ideas?
