Mower with two sickle bars

摘要

A cutter bar has spaced apart guards projecting forwardly therefrom with shearing edges cooperating with the sickle knife elements secured to two aligned sickle bars. An extension bar is secured to the inboard end of one of the sickle bars which extends in overlying relation to the inboard end of the other sickle bar. The extension carries several inverted knife elements which cooperate with upper shear edges on special guards at the inboard ends of the sickle bars.
