An agricultural conveyor assembly of the type including a main conveyor, a feed auger assembly, and a main auger boot pivotally supporting the outlet end of the feed auger assembly on the inlet end of the main conveyor for swinging movement further includes a feed auger lift assembly. The feed auger lift assembly includes: i) a support assembly pivotally supported on the main auger boot for pivotal movement with the feed auger assembly about an upright axis and which further pivotally supports the feed auger assembly thereon for relative pivoting about a horizontal lift axis; and ii) an extendable lift member coupled between the feed auger assembly and the support assembly such that the extendable lift member controls pivotal movement of the feed auger assembly about the lift axis while being movable together with the feed auger assembly about the swing axis.
