Seed bed preparation apparatus for the no-till preparation of longitudinal strips of soil for the planting of seeds in longitudinal rows including plurality of laterally spaced apart gang assemblies which are individually mounted on a draft vehicle such as a tractor or the like. Each gang assembly includes a main frame, adapted to the coupled to the draft vehicle, swingably mounting a chassis which follows the contour of the land via rotatable depth wheels which mount a forward, surface soil cutting disk for cutting a slot in the surface soil. A vertical tillage blade is received in the slot cut by the cutting wheel and includes an under surface soil lifting tillage point for lifting and partially breaking up strip of soil as the apparatus forwardly moves. A pair of rotatable soil crumbling disks are mounted on the chassis, parallel to the tillage blade, on opposite side of the blade for containing and further crumbling the portion of the lifted strip of soil between the disks and the blade.
