Disc tiller road grader system and method

Groundbreaking equipment for breaking ground, comprising:

• a gang of discs, said gang of discs comprising a plurality of rotatable discs for breaking said ground;
• a road grader comprising a road grader blade, said road grader blade comprising a front surface and a rear surface behind said front surface;
• and
• a hitch mechanism positioned between said rear surface of said road grader blade and said gang of discs and being operable for removably mounting said gang of discs behind said front surface of said grader blade, whereby discharge from said gang of discs is behind said road grader blade when said road grader moves forward or preventing jamming of said discharge between said gang of discs and said rear surface of said road grader;
• a hook connection for said hitch mechanism comprising a first body, said first body defining a receptacle, said receptacle comprising an opening and a support surface, said first body further defining a first socket, said first socket being spaced apart from said receptacle in said first body;
• a second body for said hitch mechanism, said second body defining a second socket;
• a first pin secured to said second body, said first pin being receivable through said opening and engageable with said support surface of said receptacle, whereby when engaged with said support surface said first pin being pivotal with respect to said receptacle to thereby permit pivotal movement of said gang of discs with respect to said grader blade, whereby said second socket is pivotally moveable with respect to said hook connection after said first pin engages said support surface, and whereby said pivotal movement of said gang of discs with respect to said grader blade permits alignment said first socket and said second socket;
• stop surfaces positioned to engage and thereby limit said pivotal movement of said gang of discs with respect to said grader blade when said first socket and said second socket are aligned;
• and
• a second pin insertable through said first socket and said second socket when said first socket and said second socket are aligned to thereby prevent said pivotal movement of said gang of discs with respect to said grader blade and affixes said gang of discs to said grader blade, said first socket and said second socket being positioned below said receptacle when said first socket and said second socket are aligned;
• a disc support bar rotatable mounted to said gang of discs utilizing one or more support elements, at least one of said first body or said second body being mounted to said disc support bar, said at least one of said first body or said second body comprising a height smaller than a height of said gang of discs whereby when said first body and said second body are disconnected from each other and said disc support bar engages the ground then said one or more support elements are angled with respect to the ground.
