1. A sub-soil breaking and surface-soil modifying and planting combination, comprising first support means for supporting functional elements;

  • a rotary cutting blade means for rotating along and cutting a slot in upper earth soil, to a first predetermined depth, and mounted on the first support means;

    a sub-soil blade cutting means for cutting through and extending down and below said upper earth soil in sub-soil earth a second predetermined depth, and mounted on said first first support means in trailing cutting relationship to the rotary cutting blade means and aligned therewith for following within said slot, such that a sub-soil groove is formed;

    a sub-soil earth-filler means for collapsing side walls defining said slot and said groove to effect a substantially filling-in of soil into said groove;

    a rotary tine-wheel means for preparing a seed bed and mounted on said first support means and aligned with each of the sub-soil blade cutting means and the sub-soil earth-filler means in trailing relationship thereto for following filled-in-earth prepared by said sub soil earth filler means; and

    a planter means for planting into prepared seed bed prepared by said rotary tine-wheel means;

    said sub-soil earth-filler means being mounted on said first support means;

    said planter means being mounted on the first support means such that the planter means follows in a trailing relationship to the rotary tine-wheel means;

    said sub-soil earth-filler means including a rotatable wheel-like element having blunted tines extending radially outwardly from a hub, some of the blunted tines extending laterally in one direction and others extending laterally in an opposite direction, the lateral directions being lateral relative to a plane of rotation of the rotatable wheel-like element, and a predetermined dimension between terminal ends of the tines extending in said one direction and tines extending in said opposite direction being substantially larger than the predetermined with of said groove such that the terminal ends are adapted to collapse said side walls of the groove, and when the rotating wheel-like element is rotated along the sub-soil slot.
