1. In a concrete production system including a mobile chassis having front and rear ends and opposite sides, a tank mounted across said chassis between its opposite sides for storing ingredients for making concrete and having an outboard side extending along one side of said chassis, a mixing auger for receiving and mixing said ingredients into concrete, and means on said chassis for conveying said ingredients to said mixing auger, an improved mounting and storage arrangement for said mixing auger which comprises:

  • (a) means defining an elongated cavity within said outboard side of said tank which cavity opens outwardly from said one side of said mobile chassis;

    (b) means mounting said mixing auger at its lower end to a rear corner of said mobile chassis formed by said rear end and said one side of said chassis, said mounting means supporting said auger to pivotal swinging movement between raised and lowered positions about a first axis and between side and rear transverse positions about a second axis extending in generally orthogonal relationship to said first axis whereby said auger can be pivotally moved between a storage position, wherein a portion of said auger is fitted within said elongated cavity, and a range of operating positions located about said rear corner of said chassis; and

    (c) means connecting said auger at its upper end to said mobile chassis and being operable for positioning said auger at selected positions between said raised and lowered positions and said side and rear transverse positions, said auger connecting and positioning means including(i) a first actuator supported on said chassis and having an end interconnected to said upper end of said auger and movable along a first path between extended and retracted positions for pivotally moving said auger between said raised and lowered positions about said first axis, and(ii) a second actuator supported on said chassis and having an end interconnected to said upper end of said auger and movable along a second path between extended and retracted positions for pivotally moving said auger between said side and rear transverse positions about said second axis.
