ABSTRACT:
A support and elevating structure for an auger tube which is carried by a chassis and comprises lifting elements between the chassis and the auger tube for elevation and lowering of the discharge end of the auger tube between lower and elevated positions, there being position adjustment elements between the chassis and auger tube so arranged that upon lowering, the auger tube moves downward and rearwardly so that the center of gravity remains vertically above the chassis and does not move forwardly thereof, thereby always ensuring that the auger tube is in a stable relationship with respect to the chassis and is unlikely to topple either when elevated and in use or when retracted over the chassis.
