ABSTRACT:
A portable earth boring machine for the boring of vertically inclined shafts and the insertion of pipeline casing sections characterized by a main frame portion that supports the auger drive and casing pusher apparatus, and a detachably mounted engine frame portion that permits the transmission of power between the engine and the auger drive and casing pusher apparatus not only when the engine frame portion is positioned on the main frame portion at the boring location but also when said engine frame portion is detached and positioned at a location remote from the main frame means. The machine is further characterized by a novel control means for the casing pusher apparatus that provides for both relatively slow and relatively fast extension and retraction of the casing pusher so as to provide more efficient operation of the earth boring machine.
