A method for the maintenance or extension of the range of functions of a self-propelled machine, in particular a tandem roller, single-drum roller, rubber-wheeled roller, refuse compactor, road finisher, road milling machine, recycler or stabilizer, comprising the steps: generating a code which can be identified at a short distance by a control device of the machine either automatically by the control device after a maintenance interval has expired, or after a request by an operator for an extension of the range of functions, wherein the code contains information about at least one machine state that changes in the course of operation of the machine, identifying the code by a mobile terminal, transmitting the information contained in the code to a central server, transmitting a release code from the server to the mobile terminal, transmitting the release code to the control device of the machine, enabling the maintenance interval or the extension of the range of functions.

A scraper assembly for a construction machine includes a housing pivotally coupled to a frame of the construction machine for moving the scraper assembly between a stowed position and a deployed position. The scraper assembly also includes a scraper partially received within the housing. In the deployed position of the scraper assembly, the scraper engages with a machine component to remove material stuck to the machine component. The scraper assembly further includes a biasing device received within housing. The biasing device biases the scraper towards the machine component. Further, the biasing device travels in a substantially linear path for biasing the scraper towards the machine component.

A tandem roller for compacting an underlying ground, comprising a machine frame supported by a front compaction drum with respect to a direction of travel and a rear compaction drum with respect to the direction of travel, the rear compaction drum being spaced apart from the front compaction drum in a longitudinal machine direction, and an operator platform with a driver's seat oriented in the direction of travel, the driver's seat being displaceable by means of an adjusting device from an operating position at a center of the operator platform with respect to the horizontal extension of the operator platform transverse to a forward direction in the direction of at least one side of the tandem roller transversely to the longitudinal machine direction to at least one defined first operating position and in the same direction to the side to at least one defined second operating position, the defined second operating position being spaced farther apart from the center of the operator platform than the defined first operating position.

An autonomous machine control system is disclosed. The autonomous machine control system may include a controller configured to: cause an initiation of an autonomous mode of a machine, the autonomous mode providing automatic control of a propulsion operation, a steering operation, and a work operation of the machine; determine that automatic control of the work operation is to be disabled in the autonomous mode of the machine; and cause automatic control of the work operation to be disabled in the autonomous mode of the machine, while automatic control of the propulsion operation and the steering operation is enabled in the autonomous mode of the machine.

An apparatus for contouring particulate material may include a frame and at least one drum rotatably mounted on the frame such that the drum rotates substantially freely with respect to the frame about a central longitudinal axis. The drum may have opposite inboard and outboard ends and an outer surface therebetween. At least one blade may extend about the drum and protrude outwardly from the outer surface of the drum, and the blade may have an outer edge with a radius measured from the central longitudinal axis in a plane oriented in perpendicular to the central longitudinal axis of the drum to the outer edge. The outer edge of the blade may have a helical shape and the radius of the outer edge may be less at the outboard end of the drum than the radius of the outer edge at the inboard end of the drum.
