Abstract: A machine suitable for use in spreading and laying a seed mursery strip, especially, a lawn nursery strip over the ground is equipped with means for spreading and laying the seed nursery strip over the ground; means for firming the thus-laid seed nursery strip; and means for clawing the top soil of the ground in front of the spreading and laying means and then evenly sprinkling the thus-clawed top soil as top dressing soil over the thus-firmed seed nursery strip. The seed nursery strip can thus be automatically and stably spread and laid even if they have somewhat weak tensile strength and at the same time, top dressing soil can be applied over the thus-laid nursery strips.
