A suspension for a vehicle is provided. The suspension includes, for example, a frame, at least one drive assembly, at least one front caster pivot arm, and a link that is extendible in length. The link that is extendible in length is coupled to the drive assembly and the at least one caster pivot arm such that motion of the drive assembly is transferred to the at least one caster pivot arm by the link. Torque applied by the drive assembly extends the link to a maximum length and then urges the front caster upward with respect to a support surface. |
