The present invention provides a swing-away stair assembly including a pivot bracket assembly for supporting a stair body for pivotal movement on a work machine, such as a landfill compactor. The pivot bracket assembly includes a stair support sub-assembly having an attachment portion for attaching to the stair body and a pivot portion spaced from the attachment portion. The pivot bracket assembly further includes a pivot mount sub-assembly for attaching the swing-away assembly to the lateral side of the machine, the pivot mount sub-assembly including a mounting portion for attaching to the lateral side of the machine and a pivot portion spaced from the mounting portion. A hinge member cooperates with the stair support sub-assembly and the pivot mount sub-assembly whereby the stair support sub-assembly is supported for pivotal movement relative to the pivot mount sub-assembly for supporting the stair for pivotal movement relative to the lateral side of the machine. The hinge member provides a pivot axis for the stair body which is located laterally outwardly from the lateral side of the work machine whereby the stair body is supported for movement around a rear wheel of the work machine, and is capable of 180° of pivotal movement between an operational position extending over the rear wheel and an access position displaced from the rear wheel.
