摘要

An upper support mechanism for an unloader auger tube of a combine having a ball mechanism fixed atop the unloader auger tube and a bushing having a generally spherical opening for swivellably receiving the ball member. The bushing is slidable up and down within a cylindrical opening formed in a sleeve member fixed with the combine frame. The bushing is made of a material that generally does not require lubrication as it rubs against the ball member or the sleeve member.
