The invention includes a frame, to which is mounted a handle, an engine, drive wheels and an auger. The engine drives the drive wheels, making the apparatus self-propelled and also rotates the auger. Control levers are located on the handle to selectively control the on-off engagement of the drive wheels and the auger to the engine and to control the speed of the drive wheels. As the apparatus propels itself along a trench, the rotating auger moves dirt from the sides of the ground around the trench to inside of the trench. A packer wheel on the handle packs the dirt in the filled trench. The height of the auger relative to the ground is adjustable so as to minimize lawn damage. The auger has a double row of flighting and guide wheels positioned adjacent to the auger to enable the apparatus to be easily steered.
