Abstract

A combination tillage apparatus for towing behind a tractor comprises an extended frame having a trunk member oriented along the direction of travel of the apparatus and at least one pair of parallel and spaced apart branch members oriented perpendicularly to the trunk member. Each one of a pluralilty of implements is mounted in a mounting mechanism and a stabilizing mechanism which provide independent angular, translational, and vertical adjustment of each of the implements relative to the frame. A first modified embodiment of the combination tillage apparatus allows angular adjustment of the implement relative to the stabilizing mechanism independently from the angular adjustment of the stabilizing mechanism relative to the frame. A second modified embodiment of the combination tillage apparatus comprises a compact frame for towing behind a garden tractor, a yoke in combination with a wheel and a strut for providing either fixed angular orientation of the implement relative to the frame or fixed angular orientation of the implement relative to the direction of travel of the apparatus, and a motor and a shaft for driving a hydraulically powered implement. A third modified embodiment of the combination tillage apparatus provides mounting mechanisms of each of the other embodiments mounted on a plurality of the compact frames connected in tandem.

(a) said attachment means includes said post dimensioned to be slidably insertable through said aperture; and

(b) said implement having a bearing plate perpendicularly rigidly secured to said post for operably abutting said platform.

3. A combination soil tilling apparatus according to claim 1 wherein:

(a) said attachment means includes an implement sleeve having a bearing plate perpendicularly rigidly secured to an end thereof and a sleeve throughbore;

said implement sleeve dimensioned to be slidably insertable through said aperture such that said bearing plate operably abuts said platform; and

(b) said post dimensioned to be slidably insertable in and through said implement sleeve;

4. The combination soil tilling apparatus according to claim 3 wherein said securement means includes:

(a) a keyway rigidly secured to an outer surface of said post sleeve;

(b) a notch in said implement sleeve for cooperative alignment with said keyway;

said notch spaced such that said bearing plate and said stabilizing plate are secured in substantially abutting relationship with said platform as said notch is cooperatively aligned with said keyway;

(c) a key for slidable insertion through said keyway and said cooperatively aligned notch such that said implement sleeve is substantially rigidly secured to said stabilizing mechanism when said key is positioned in said keyway and such that adjustment of the angular orientation of said stabilizing mechanism relative to said mounting mechanism simultaneously adjusts the angular orientation of said implement sleeve relative to said mounting mechanism; and

(d) a keeper for removably securing said key in said keyway.

5. The combination soil tilling apparatus according to claim 2 wherein said securement means includes:

(a) said post sleeve having at least one diametrical transverse post sleeve throughbore;

(b) said post having a plurality of diametrical transverse post throughbores for selective alignment with said post sleeve throughbore;
