Abstract

A grading device is attachable to skid steer equipment. The device is fashioned as a standard bucket attachment secured to a box or dozer blade. The bucket attachment is configured to secure to the universal attachment arm of skid steer equipment.

Claims

1. A grading attachment, comprising:

a grading frame having an outer support sleeve attached thereto via a plurality of support braces;

an inner support shaft secured to an end of said outer support sleeve further having a distal end directly affixed to a base plate;

an attachment blank affixed to said base plate;

a plurality of stiffening plates each connected to said grading frame;

a front blade hingedly attached to each of said stiffening plates;

a plurality of gusset plates affixing said inner support shaft to said base plate;

a plurality of wear plates affixed to lower surfaces of said grading frame;

an abrasion wear plate attached to said front blade; and

a plurality of tilling bars each held in position between adjacent ones of said stiffening plates;

wherein said inner support shaft rotates within said outer support sleeve;

wherein said attachment blank is configured to attach to a skid steer loading machine thereby enabling said skid steer loading machine to operably control said grading attachment;

wherein each of said wear plates further comprises high carbon steel;

wherein a plurality of teeth further comprises high carbon steel;

wherein said grading frame comprises a hydraulic cylinder secured to said base plate at a first end and secured to said grading frame at a second end;

wherein movement of said hydraulic cylinder in a first direction moves said grading frame in a first direction;

wherein movement of said hydraulic cylinder in a second direction moves said grading frame in a second direction;

wherein said grading frame further comprises a rectangular shape; and

wherein each of said tilling bars further comprise said high carbon steel teeth.

2. A grading machine, comprising:

a skid steer loading machine;

a grading frame having an outer support sleeve attached thereto via a plurality of support braces;

an inner support shaft secured to an end of said outer support sleeve further having a distal end affixed to a base plate;

an attachment blank affixed to said base plate;

a plurality of stiffening plates each connected to said grading frame;

a front blade hingedly attached to each of said stiffening plates;

a plurality of gusset plates affixing said inner support shaft to said base plate;

a plurality of wear plates affixed to lower surfaces of said grading frame;

an abrasion wear plate attached to said front blade;

a plurality of tilling bars each held in position between adjacent ones of said stiffening plates; and

wherein said inner support shaft rotates within said outer support sleeve;

wherein said attachment blank is configured to attach to a skid steer loading machine, thereby enabling said skid steer loading machine to operably control said grading attachment;

wherein each of said wear plates further comprises high carbon steel;

wherein each of said tilling bars further comprise a plurality of teeth; and

wherein said teeth further comprise high carbon steel; and

wherein said grading frame further comprises a rectangular shape.

3. A grading attachment, comprising:

a grading frame having an outer support sleeve attached thereto via a plurality of support braces;

an inner support shaft secured to an end of said outer support sleeve further having a distal end affixed to a base plate;

an attachment blank affixed to said base plate;

a plurality of stiffening plates each connected to said grading frame;

a front blade hingedly attached to each of said stiffening plates;

a hydraulic cylinder secured to said base plate at a first end and secured to said grading frame at a second end;

a plurality of gusset plates affixing said inner support shaft to said base plate;

a plurality of wear plates affixed to lower surfaces of said grading frame;

an abrasion wear plate attached to said front blade; and

a plurality of tilling bars each held in position between adjacent ones of said stiffening plates;

wherein said inner support shaft rotates within said outer support sleeve;

wherein said attachment blank is configured to attach to a skid steer loading machine thereby enabling said skid steer loading machine to operably control said grading attachment;

wherein movement of said hydraulic cylinder in a first direction moves said grading frame in a first direction;

wherein movement of said hydraulic cylinder in a second direction moves said grading frame in a second direction; and

wherein each of said tilling bars further comprise a plurality of high carbon steel teeth.
