FIELD: agriculture; machine building.
SUBSTANCE: invention relates to a drive device for an assembly of a self-propelled harvester consisting of a replaceable cutting device and/or inclined feeder. Drive device comprises a system with a device for continuously changing a gear ratio and connected behind it reduction gear. Transmission system comprises as first transmission with loose interlinking a variator. Variator includes first variator pulley driven by engine and second variator pulley on power takeoff side. Pulleys are configured for continuous adjustment of working diameters. Second variator pulley can drive located on one axis with it a drive pulley of second transmission with loose interlinking. Drive pulley of second gear is kinematically connected by flexible link with one of drive pulleys. Drive pulleys are intended for driving inclined feeder and for drive of replaceable cutting device. Between corresponding drive pulley and drive of inclined feeder or replaceable cutting device there is a reduction gear.
EFFECT: reliable and high specific power with compact design.
