Abstract
A grading bar leveling ground includes a panel formed as a blade having a forward-facing-surface and a backward-facing-surface, a plurality of gussets, at least one horizontal member coupled to the panel, and a support-and-coupling-member. The grading bar is attachable to an implement including machine such as a front loader tractor, a skid steer loader, an excavator backhoe, a tractor backhoe, or a rear three point tractor hitch and is configured for smoothing and leveling ground as manipulated by the implement.
Claims
exact text as granted — not AI-modifiedWhat is claimed is new and desired to be protected by Letters Patent is set forth in the appended claims:
1 . A grading bar comprising:
a panel formed as a blade having a forward-facing-surface and a backward-facing-surface; a plurality of gussets, said plurality of gussets being independently coupled to said backward-facing-surface of said panel; at least one horizontal member coupled to said panel, said at least one horizontal member extending from a first end of said panel to a second end of said panel to provide rigidity to said panel; a support-and-coupling-member, said support-and-coupling-member coupled to said backward facing surface of said panel; wherein said forward-facing-surface is non-arcuate in profile and is planar across its entire surface and does not comprise edge-extension caps; and wherein said grading bar is attachable to an implement and is configured for leveling ground as manipulated by said implement.
2 . The grading bar of claim 1 , further comprising an anchor, said anchor being removably attached to said at least one horizontal member and said support-and-coupling-member.
3 . The grading bar of claim 2 , wherein said anchor is adapted for removable attachment to said implement comprising a machine selected from the group consisting of a front loader tractor, a skid steer loader, an excavator backhoe, a tractor backhoe, and a rear three point tractor hitch.
4 . The grading bar of claim 2 , wherein said anchor includes a plurality of attachment points to provide semi-universal attachment means.
5 . The grading bar of claim 4 , wherein said plurality of attachment points includes at least 4 attachment points.
6 . The grading bar of claim 2 , wherein said anchor comprises at least one plate-like structure.
7 . The grading bar of claim 6 , wherein said anchor further comprises a plurality of ears extending from said plate-like structure.
8 . The grading bar of claim 7 , wherein said plurality of ears includes two protruding elements.
9 . The grading bar of claim 8 , wherein each of said two protruding elements extend from a top of said plate-like structure to a bottom of said plate-like structure.
10 . The grading bar of claim 8 , wherein each of said two protruding elements includes an opening.
11 . The grading bar of claim 10 , wherein said opening has an open circular cross-sectional shape suitable for ready attachment to said implement.
12 . The grading bar of claim 2 , wherein said at least one support member is positioned equidistant from said first end of said panel to said second end of said panel.
13 . The grading bar of claim 2 , wherein said support member is an elongate member positioned between two of said plurality of gussets.
14 . The grading bar of claim 1 , wherein said plurality of gussets includes 4 wedges.
15 . The grading bar of claim 1 , wherein said plurality of gussets extend substantially from a top of said panel to an upper surface of said horizontal member to promote vertical stability and rigidity.
16 . The grading bar of claim 1 , wherein said support-and-coupling-member comprises cammed-surfaces for ease of attachment to said implement.
17 . A grading bar for leveling ground, comprising:
a panel formed as a blade having a forward-facing-surface and a backward-facing-surface; a plurality of gussets, said plurality of gussets being independently coupled to said backward-facing-surface of said panel; at least one horizontal member coupled to said panel, said at least one horizontal member extending from a first end of said panel to a second end of said panel to provide rigidity to said panel; a support-and-coupling-member, said support-and-coupling-member coupled to said backward facing surface of said panel; an anchor, said anchor being removably attached to said at least one horizontal member and said support-and-coupling-member; wherein said anchor includes a plurality of attachment points to provide semi-universal attachment means; wherein said plurality of attachment points includes at least 4 attachment points; wherein said anchor comprises two parallel-mounted plate-like structures forming a boxed-section; wherein said anchor further comprises a plurality of ears each extending from said plate-like structure; wherein said plurality of ears includes two protruding elements; wherein each of said two protruding elements extend from a top of said plate-like structure to a bottom of said plate-like structure; wherein each of said two protruding elements includes an opening; wherein said opening has an open circular cross-sectional shape suitable for ready attachment to an implement; wherein said at least one support member is positioned equidistant from said first end of said panel to said second end of said panel; wherein said support member is an elongate member positioned between two of said plurality of gussets; wherein said plurality of gussets includes 4 wedges; wherein said plurality of gussets extend substantially from a top of said panel to an upper surface of said horizontal member to promote vertical stability and rigidity; wherein said support-and-coupling-member comprises cammed-surfaces for ease of attachment to said implement; wherein said forward-facing-surface is non-arcuate in profile and is planar across its entire surface and does not comprise edge-extension caps; and wherein said grading bar is attachable to said implement and is configured for leveling ground surfaces as manipulated by said implement.Join the waitlist — get patent alerts
