Abstract
The arcuate processing assembly of a combine harvester may be pivotally adjusted generally radially toward or away from a rotary processing device to adjust the operating clearance between the periphery of the rotary device and the assembly. Simultaneously with such adjustment of the assembly as a whole, in a compound pivoting action one arcuate member of the assembly is also pivoted relative to the other arcuate member to properly reshape the threshing region for the adjusted running clearance.
