ABSTRACT:
A soil mixing apparatus that requires less drilling force comprises a shaft, a plurality of cutting blades, an excavation blade, an auger bit, a shear blade having an extendible finger. The cutting blades, excavation blade and auger bit are attached to rotate with the shaft. The shear blade is attached at a fixed longitudinal position along the shaft. The shear blade provides a variable length by attaching different length fingers that are adjustable to the soil conditions in which the mixing apparatus is used. The shear blade is also mounted to the shaft at an angle such that the shear blade rotates in the same direction as the excavation blade and the cutting blades, but at a much slower rotation rate.
