Abstract
A combine having a header on the forward end of it which operates to cut and deliver crop material to an elevator in a feeder house over which a cab is provided at an elevated location. The elevator delivers the material to the threshing mechanism of the combine. The engine of the combine is connected by a belt drive to a vari-drive supported by the feeder house and a yoke on the vari-drive moves one flange of the adjustable sheave of the vari-drive relative to the other. An auxiliary motor actuates the yoke by driving a rotatable screw and a Bowden cable is connected between a pivoted speed-indicating needle on a dial mounted in view of the cab and the follower of the yoke which is actuated by the screw which is operated to move the yoke to change the adjustable sheave and vary the speed of operation of the combine.
