The disclosure relates to a steering column which is capable of moving four ways. The steering column has a base support affixed to a horizontal cab floor. The base support has a steering motor. The steering column has an input shaft with a upper telescoping shaft. Attached to the upper telescoping shaft is the steering wheel. Also attached to the upper telescoping shaft is the upper input shaft. The first universal joint connects the upper input shaft to the inner input shaft. Torque is transferred by a key on the exterior circumference of the inner input shaft to a key slot on the interior circumference of the outer input shaft. The outer input shaft is connected to the lower input shaft by the second universal joint. The lower input shaft is connected to the steering motor. Attached to the base support is the lower pivot assembly. The lower pivot assembly rotates about the base support by actuating a lower gas cylinder. The lower pivot assembly can translate by operating the lower locking knob. The upper pivot assembly is attached to the lower pivot assembly. The upper pivot assembly can pivot by actuating an upper gas cylinder.
