Abstract
A combine harvester comprises a separating apparatus arranged to receive a threshed crop stream and convey rearwardly. The separating apparatus comprises a grate for allowing grain and chaff to fall onto an underlying separator pan, the separator pan being driven in an oscillating manner to convey a grain/chaff stream forwardly for delivery to a cleaning unit. The separator pan comprises a first portion and a second portion disposed forwardly of the first portion. A rear edge of the second portion is releasably attached to a front edge of the first portion, the second portion being pivotable around a forward mounting around a transverse axis between an operating position in which the second portion is attached to the first portion forming a continuous pan surface, and a lowered position in which the second portion is detached from the first portion giving maintenance access to the underside of the separating apparatus.
