Abstract
Abstract An earth auger arrangement wherein a power source is mounted on wheels for moving the power source over the earth's surface with means connected to the power source for relaying power to a transmission with which an auger is connected. Handle means are connected to the transmission for manually positioning the auger in relation to the earth's surface to penetrate it at a desired angle with throttle means on the handle means to control the power source. Shaft means are pivotally connected to and extend between the power source and the handle means to reduce counter rotation or counter torque from being exerted on the operator when the auger is rotated to penetrate the earth.
