1. A combination soil tilling apparatus for connecting to and towing behind a tractor and for tilling underlying soil, comprising:

  • (a) at least one mounting mechanism having a pair of parallel and spaced apart frame sleeves rigidly secured together by an interconnecting platform;

    at least one of said pair of frame sleeves having a substantially vertically oriented pinhole;

    said platform having a generally centrally spaced aperture and an angular adjustment platform throughbore;

    (b) a frame having a trunk member positioned along the direction of travel of said apparatus;

    said frame further having a pair of branch members rigidly secured substantially perpendicularly to said trunk member;

    each one of said pair of branch members aligned parallel to one another and spaced apart such that said pair of branch members are slidably receivable in and through said pair of frame sleeves;

    said branch members having a plurality of frame throughbores spaced for selective alignment with said pinhole;

    (c) a frame pin for transitional adjustment of said mounting mechanism relative to said frame;

    said frame pin adapted to be slidably insertable through said pinhole and a selected one of said plurality of frame throughbores;

    (d) at least one implement for tilling the soil;

    said implement having attachment means including a post for operably attaching said implement to said mounting mechanism;

    (e) a stabilizing mechanism for stabilizing said post relative to said mounting mechanism;

    said stabilizing mechanism including a stabilizing plate and a post sleeve dimensioned to slidably telescope over the distal end of said post;

    said stabilizing plate rigidly perpendicularly secured to an end of said post sleeve such that said stabilizing plate operably abuts said platform;

    said stabilizing plate having a plurality of angular adjustment throughbores spaced for selective alignment with said platform throughbore;

    (f) an angular adjustment pin for angular adjustment of said stabilizing mechanism relative to said platform;

    said angular adjustment pin adapted to be slidably insertable through a selected one of said plurality of angular adjustment throughbores and said platform throughbore;

    (g) securement means for operably securing the relative spacing of said mounting mechanism, said implement, and said stabilizing mechanism; and

    (h) support means for generally maintaining the spacing of said implement relative to the underlying soil.
