A grain auger has a frame, a conveyor mounted on the frame for movement between a lowered transport position and a raised use position, and an axle with a pair of wheels to rollably support the auger. The axle has angular disposed hollow members with telescoping arms extending therefrom so that the length and height of the axle is adjustable. A cradle is provided on top of the axle, with a support block at the top of the lift assembly for nesting in the cradle when the conveyor is in the lowered transport position, to minimize the cantilever of the conveyor during transport.
