An apparatus for forming a hole in ground ( 10 ) includes a mounting plate ( 60 ) mounted to a loader ( 80 ). A probe ( 11 ) is coupled with the mounting plate ( 60 ). Two arms ( 32 ) extend radially outward from a vertical axis and from a periphery of the probe ( 11 ). The apparatus further includes two cylinders ( 40 ) each having an upper end ( 42 ) coupled to the mounting plate ( 60 ) and a lower end ( 44 ) coupled to one of the arms ( 32 ). The probe ( 11 ) is driven into the ground along the vertical axis by movement of the mounting plate ( 60 ) by the loader ( 80 ), and an upper portion of the probe ( 11 ) is simultaneously wobbled about two axes that are perpendicular to each other and to the vertical axis by moving at least one of the cylinders ( 40 ). The probe ( 11 ) is then moved out of the ground to leave a hole in the ground.
