A single width operator seat (129) rotates and translates, in the confined space of the operator cab, between two opposed vehicle operating stations (104,106). In both positions the operator is able to operate the controls. The seat (129) is mounted on an upper plate (154), supported by bearings (164) and therefore can move easily with respect to the lower plate (156). Cam followers (165, 167) that are fixed to the upper plate (154) are guided in cam tracks (180, 182) disposed in the lower plate (156), to define a curved path.
