    Abstract: A land smoother and packer system for smoothing and packing irregularities in a ground surface. The inventive device includes a frame, a plurality of wheels, a right blade pivotally attached to the frame, a center blade attached to the frame, a left blade pivotally attached to the frame, and a plurality of rollers rotatably attached to the frame behind the blades. The frame has a center portion, a left wing and a right wing that fold upon the center portion for travel. A pair of hydraulic cylinders are attached to the right blade and the left blade for controlling the rotational position of the respective blades. The plurality of rollers are preferably comprised of a center roller, a right roller, a left roller, a right rear roller, and a left rear roller. In operation, the blades are lowered to the desired level for leveling the ground surface of dirt mounds. The rollers follow behind the blades thereby packing the ground surface and forcing any rocks into the ground surface.
