Earth working machine whose rotatable working apparatus, for installation on the machine, is conveyable into its operating position using an onboard actuator

An earth working machine, comprising:

• a machine frame;
• a drive configuration rotatable relative to the machine frame about a drive axis, the drive axis defining an axial direction;
• a working apparatus releasably connectable to the drive configuration in an operating position wherein rotation of the drive configuration transfers torque to the working apparatus for rotation of the drive configuration and the working apparatus together about the drive axis for earth working, the working apparatus being configured such that when a connection between the working apparatus and the drive configuration is released the working apparatus is removable from the operating position in an axial direction relative to the drive configuration for deinstallation of the working apparatus from the drive configuration, and the working apparatus being configured such that the working apparatus is conveyable into the operating position in an axial direction relative to the drive configuration for installation of the working apparatus on the drive configuration;
• and
• an actuator mounted on the drive configuration and including an actuator member movable relative to the drive configuration into installation force transferring engagement with the working apparatus when the working apparatus is in a preparation position located axially remotely from the operating position, the actuator being configured to move the working apparatus from the preparation position closer to the operating position.
