A self-propelled vehicle capable of making turns with tight turning radii, which comprises a frame with a pair of traction wheels, at least one orientable wheel, and one or more driver's posts. The vehicle has a single motor that is kinematically connected to a driving shaft and means for functional connection between the driving shaft and each one of the two traction wheels. Each one of the two traction wheels can therefore be actuated independently of the other thanks to the presence of steering means suitable to act on the connection means. |
