Abstract: An earth anchor (1) comprises a hub body (3) having a base plate (7). A shank (19) extends downwardly from a bottom surface (21) of the plate. The shank has a beveled lower edge (23) forming a tip (25) for penetrating the ground. A hub (9) extends upwardly from an upper surface (11) of the plate and non-drivingly engages the drive tool. A quadrilaterally formed circumferential side wall (17) extends upwardly from the outer margine of the plate. The side wall is spaced radially outwardly of the hub and forms a sleeve in which a portion of the drive tool is received. The base plate, hub, shank, and side wall are all integrally formed, preferably through forging or casting, forming a hub body of uniform strength, less subject to stress forces, and relatively tight dimensional tolerances. A blade (5) is attachable externally to the hub body.
