Drive and steering mechanism for a vehicle embodying a frame supported by a pair of transversely spaced wheels separately connected to a pair of transverse shafts rotatable about a common axis with adjacent ends being rotatable relative to each other. A sleeve mounted non-rotatably on adjacent ends of the shafts is movable axially of the shafts to a first position in contact with both ends of the shafts so that both shafts rotate as a unit and to a second position in engagement with only one of the adjacent ends. Drive means connected to one of the shafts rotates the same while the sleeve is in the second position and rotates both shafts while the sleeve is in the first position.
