A ladder for use with heavy machinery such as farm equipment, the ladder having platform steps, the ladder being convertible between a deployed position for supporting a person or other load, to a storage, scaffold, or ramp position in which the steps lie in a generally planar arrangement. When deployed, the ladder steps remain parallel to each other. The ladder includes two frames, the frames pivotably connected by a plurality of platform steps, one of the frames being pivotably attached to a piece of heavy machinery. The frame nest within one another in the storage configuration. The pivotable attachment to the heavy equipment may be wheels on the ladder frame that engage horizontal tracks on the heavy equipment, allowing the ladder to be lifted up, the frames nested, and the ladder in the storage configuration slid along the tracks and stored.
