Abstract
A combine harvester where opposing concaves on either side of a rotor of a processing system substantially simultaneously travel symmetrical paths. The concaves of the processing system may be pivotally supported on a rockshaft where the axis of the rockshaft moves in a generally vertical manner so that the concaves then move generally radially toward or away from the rotor.
