CONCAVE ADJUSTMENT MECHANISM

摘要

A combine harvester (10) where opposing concaves (24) on either side of a rotor (22) of a processing system substantially simultaneously travel symmetrical paths. The concaves of the processing system may be pivotally supported on a rockshaft (62) 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.
