摘要：
Steered caster wheel systems that include a disengagement system to enable a caster wheel steering mode and non-caster wheel steering mode are disclosed. In some embodiments, the caster wheels are mounted to a subframe that may be independently suspended from the chassis of a vehicle such as a self-propelled vehicle.
