<p>A mobile grain auger having an elongated cylindrical casing having an intake end and a discharge end, a helicoidal auger flight extending through the casing, a motor to rotate the flight to convey grain from the intake end to the discharge end of the casing, two legs defining a calliper frame and having their divergent ends supporting the casing at spaced positions along its length. A pair of coaxial ground wheels support a horizontal pivotal axis about which the frame is liftable in the place of the casing's longitudinal axis. First adjustment means are operable to change the calliper angle, a reaction member is positioned to engage the ground between the common axis of the wheels and the intake end of the casing. A tilt adjustment means is connected between the frame and the reaction member and is operable to vary the slope of the casing in a controlled manner.</p> |
