Abstract

A dirt grading implement consisting of a mounting plate having a front side, a back side, a left side, a right side, and having a lower end, the back side of the mounting plate being adapted for removable attachment to the boom arm or lift arms of mobile earth moving equipment; a bar fixedly attached to the lower end of the mounting plate, the bar having a leftwardly extending section and a rightwardly extending section, the sections extending respectively leftwardly and rightwardly from the left and right sides of the mounting plate, the bar having a forwardly oriented face and a downwardly oriented dirt engaging face.

Claims

1. A dirt grading implement having a lowermost surface, the dirt grading implement comprising:

(a) a mounting plate having a front side, a back side, a left side, a right side, and having a lower end, the back side of the mounting plate being adapted for removable attachment to the lift arms of a skid steer loader, to the lift arm of a front loader tractor, to the boom arm of an excavator or tractor backhoe, or to a rear three point tractor hitch; and

,

(b) a bar fixedly attached to the lower end of the mounting plate, the bar comprising a central section, a leftwardly extending section and a rightwardly extending section, the leftwardly and rightwardly extending sections respectively extending leftwardly and rightwardly from the left and right sides of the mounting plate, the bar having a forwardly oriented dirt engaging face and a downwardly oriented dirt engaging face, the downwardly oriented dirt engaging face comprising the lowermost surface, the bar further having a rearwardly oriented dirt engaging face, the downwardly oriented dirt engaging face spanning between the forwardly oriented dirt engaging face and the rearwardly oriented dirt engaging face, the bar further having a plurality of arcuately curved implement deflecting faces, each implement deflecting face being positioned at a juncture between dirt engaging faces.

2. The dirt grading implement of claim 1 further comprising left and right dirt catching panels fixedly attached to the bar, the left and right dirt catching panels being positioned for resisting a passage of dirt over the leftwardly and rightwardly extending sections of the bar.

3. The dirt grading implement of claim 1 further comprising removable attaching means, the removable attaching means interconnecting the leftwardly extending, central, and rightwardly extending sections of the bar.

4. The dirt grading implement of claim 3 wherein the removable attaching means comprise slip joints.

5. The dirt grading implement of claim 1 wherein the front side of the mounting plate comprises a dirt catching panel.

6. The dirt grading implement of claim 5 wherein the bar comprises a tube having a substantially square cross-sectional shape, the tube defining a hollow interior space.

7. The dirt grading implement of claim 6 further comprising metal ballast mounted within the hollow interior space of the tube.

8. A dirt grading implement having a lowermost surface, the dirt grading implement comprising:

(a) a mounting plate having a front side, a back side, a left side, a right side, and having a lower end, the back side of the mounting plate being adapted for removable attachment to the lift arms of a skid steer loader, to the lift arm of a front loader tractor, to the boom arm of an excavator or tractor backhoe, or to a rear three point tractor hitch; and

,

(b) a bar fixedly attached to the lower end of the mounting plate, the bar comprising a central section, a leftwardly extending section and a rightwardly extending section, the leftwardly and rightwardly extending sections respectively extending leftwardly and rightwardly from the left and right sides of the mounting plate, the bar having a forwardly oriented dirt engaging face and a downwardly oriented dirt engaging face, the downwardly oriented dirt engaging face comprising the lowermost surface, the bar further having a rearwardly oriented dirt engaging face, the downwardly oriented dirt engaging face spanning between the forwardly oriented dirt engaging face and the rearwardly oriented dirt engaging face, the bar further having an upwardly oriented dirt engaging face spanning between the forwardly and rearwardly oriented dirt engaging faces, the bar further having a plurality of arcuately curved implement deflecting faces, each implement deflecting face being positioned at a juncture between dirt engaging faces.

9. The dirt grading implement of claim 8 further comprising left and right dirt catching panels fixedly attached to and extending upwardly from the upwardly oriented dirt engaging face of the bar, the left and right dirt catching panels being positioned for resisting passage of dirt over the leftwardly extending and rightwardly extending sections of the bar.
