A multi-screener apparatus in which the height of the apparatus may be adjusted for the convenience of a user. This multi-screener apparatus prevents the unwanted movement of the apparatus frame without the addition of counterweights or excessive frame mass to prevent the unwanted movement. Also, this multi-screener design may function with a variety of power sources, including electrical and fossil fuel based power sources. The unit is easily placed in a desired location by optional vehicle attachment means for towing as well as gripping handles and wheels for manually positioning the apparatus in a desired location. Further, the lightweight design of the apparatus also plays an important role regarding the mobility of the apparatus.
