Abstract
A mower conditioner header has a reel which includes a plurality of rotatably mounted toothbars each carrying teeth. The toothbars are controlled during rotation of the reel so that they rock to maintain the teeth at the desired attitude relative to the crop as it is swept across a cutterbar of the harvester to be cut and then on the nip of conditioner rolls. This control of the toothbars is done by toothbar guide arms fixed to an end of each toothbar, the arms each carrying a roller which is received in an upright D-shaped cam track carried by an adjacent one of opposite side structures of the frame of the header. To permit at least one toothbar to be rotated so as to swing its associated teeth away from the vicinity of the cutterbar for permitting access for performing service on the cutterbar, the toothbar guide arm associated with this toothbar is made of inner and outer arm sections which are mounted for relative pivotal movement but which are held together for movement in unison by a selectively releasable latch pin.
