ABSTRACT:
An apparatus for and method of installing a pile in unstable soil before a building foundation is installed on that unstable soil. The apparatus includes a tractor; an arm pivotally attached to tractors; a mechanism for moving the arm between raised and lowered positions; a driving platform attached to the arm; and auxiliary weight attached to the front member of the arm. The method includes the steps of placing the first end of a starter pile on the unstable soil; positioning the driving platform of the tractor on the second end of the starter pile; and activating the mechanism for moving the arm between raised and lowered positions to move the arm to the lowered position and cause the driving platform to drive the starter pile into the unstable soil.
