FIELD: engines and pumps.
SUBSTANCE: invention relates to off-road vehicles, but can be used both during construction and in agriculture. The screw mover contains a screw in form of a hollow cylinder with screw combs on the outer surface, bearing supports at the screw end faces, and a drive engine of screw rotation. On the screw vibration exciters of the mechanical oscillations are installed with total vector of an exciting force located in a vertical plane passing through longitudinal axis of the screw, and inclined relatively to this axis in direction of movement of the screw mover.
EFFECT: invention reduces resistance to movement of the screw mover.
