A collector leaf construction for a harvester consisting of a primary leaf portion, a pivot for mounting the inboard end of the primary leaf portion on the frame of a harvester, a secondary leaf portion, a pivot for mounting the secondary leaf portion on the outboard end of the primary leaf portion, a first spring between the primary leaf portion and the frame, a second spring between the primary leaf portion and the secondary leaf portion to permit the secondary leaf portion to deflect relative to the primary leaf portion when it encounters an obstruction, the first spring being stronger than the second spring, with the secondary leaf portion extending forwardly of the leading edge of the primary leaf portion so that when the primary leaf portion is deflected, the secondary leaf portion will occupy a part of the position previously occupied by the primary leaf portion to thereby cover any opening left by the primary leaf portion when it is deflected during harvesting, and any deflection of the secondary leaf portion will not be transmitted to the primary leaf portion because the second spring is weaker than the first spring.
