ABSTRACT:
The manually pushed swing involves a vertical pole that is anchored into the ground via a concrete base, wherein a swing top mounts atop said pole and enables a plurality of swings seats and push handles to be connected thereon. The push handles enable a non-occupant to propel the plurality of swing seats around the pole via a bearing. The manually pushed swing is ideally suited for outdoor use.
