Abstract: A visor structure is provided for the cab of a harvester which has horizontal parts which extend forwardly and laterally outwardly from the top of the cab to approximately the tread of vehicle and approximately to the lateral extremities of the grain bin mounted immediately behind the cab. The visor structure supports forwardly directed operating lights and rear view mirrors. The cab is provided with an access door at one lateral side and a walkway extends laterally outwardly therefrom. The visor structure does not extend over the walkway, thus freely permitting operator ingress and egress. The visor structure also includes a part extending forwardly from the cab. The top of the visor structure, the top of the cab and the top of the grain bin lie substantially in a common horizontal plane.
