The running gear provides the  means for   moving   the generator set manually or with a tow vehicle.

A torsion axle and the associated wheels, tires, and tubes  are  the  components  that  allow easy  movement  of  the  generator set. The lunette eye is the connecting point for a towing vehicle. A swivel caster provides support for the front of the generator set and can be rotated from the down position when the set is being towed.
