Abstract
Embodiments provide safety features for a post hole digger, such as for attachment to a tractor or other utility device. The post hole digger has a boom and a yoke for pivotally connecting to the tractor or similar device, a driveline for transmitting rotational energy, and an auger for forming holes in a ground or floor surface. Rotating features of the post hole digger are isolated by various guard members, thereby enhancing the safety of the device.
