A hole digger having an anchor inserted into the ground so tines rotate in place discharging loose material from a hole being dug. The anchor includes an elongate stake carried by the transmission carrying the tines that is inserted to a depth greater than tine depth limiting tine travel to an arc about the stake. The digger can include one or more digger tines of increased axial surface area provided by an axial deflector extending radially along part of a tine facing toward the outer edge of the hole increasing the volume discharged from the hole during each tine rotation. Such a digger can be produced by modifying a garden tiller or cultivator to include an anchor mounted to its transmission and can further include one or more digger tines if desired. The anchor and deflectors can form a kit for retrofitting a tiller or cultivator into a hole digger.
