摘要： A soil preparation machine is pulled by a tractor across a field in which rows of plants and tracks followed by the tractor are at permanent locations from season to season. Soil from between the remains of two rows of the previous season's plants is lifted by a blade and delivered to the forward end of a belt conveyor which is slanted rearwardly and upwardly. Devices on the machine upturn the remains of the previous season's plants and the soil beneath them. Soil falls from the rear end of the conveyor onto the upturned remains. The blade and conveyor are narrower than the distance between the rows of plants, and the upturning devices are aligned with the rows of plants inboard of the tractor tracks.
