ABSTRACT:
A self-propelled vehicle includes front and rear wheel assemblies mounted on a frame for supporting it rollably above the ground, the front wheel assembly being swingably mounted to the front portion of the frame. A motor or engine is mounted on the front wheel assembly for driving it, and a steering column is rotatably mounted on the frame in a backwardly inclined position. A bracket enables the angular position of the steering column to be adjusted, and a linkage connects the steering column and front wheel assembly for moving the front wheel assembly angularly in response to rotational movements of the steering column for steering purposes. The axis of rotation of the front wheel assembly is disposed in a backwardly inclined position to add greater stability to the vehicle. The steering column includes a pair of telescoping members and a device for fixing them adjustably in a given axial position relative to one another for enabling the length of the steering column to be adjusted to a desired length.
