ABSTRACT:
A post hole digger having a bracket plate, a center shaft and two side shafts, each shaft with a first end and a second end. The first end of the center shaft is mounted to the bracket plate. A pair of digging blades are pivotally attached to the second end of the center shaft, with a blade pivotally attached to the second end of each side shaft. A handle is pivotally attached to the bracket plate and to the first end of each side shaft. As the handles are rotated with respect to one another, the side shafts move axially with respect to the center shaft to open and close the digging blades. The shafts are held approximately parallel and in spaced relation to one another during operation of the digger so that the hole has an approximately constant diameter. A detent mechanism is provided for indicating when the digging blades are oriented approximately parallel to one another for insertion into the ground. Extension rods increase the operating length of the shafts to allow digging deeper holes.
