Drag bar for levelling ground

A drag bar apparatus for attachment to a tractor allowing levelling a surface of ground over which the tractor passes, the tractor having forwardly projecting forks for engaging the drag bar apparatus, the apparatus comprising:

• a frame having a generally planar body for resting on the ground;
• wherein the frame includes a mounting coupling for attachment to a front support of the tractor for movement in a forward and rearward direction by the tractor in a levelling action;
• the frame including a front transverse member and a rear transverse member forming two parallel components for engaging the ground sequentially as the frame is moved forwardly and rearwardly over the ground;
• the front transverse member comprising a plate having downward projecting ground scraping elements for breaking the surface of the ground;
• the rear transverse member having a leveling surface for compressing and levelling the surface of the ground;
• wherein the plate has front and rear edges each of which is shaped in a plane of the plate to define a wave pattern;
• and wherein the plate carries front and rear rows of said ground scraping element and wherein the wave patterns are out of phase so that the ground scraping elements are arranged with the ground scraping elements of the front row alternately offset from the ground scraping elements of the rear row.

A drag bar apparatus for attachment to a tractor allowing levelling a surface of ground over which the tractor passes for use with gravel roads having traffic wheel strips, the tractor having forwardly projecting forks for engaging the drag bar apparatus, the apparatus comprising:

• a frame having a generally planar body for resting on the ground;
• wherein the frame includes a mounting coupling for attachment to a front support of the tractor for movement by the tractor in a levelling action;
• the frame including a first transverse member having downward projecting ground scraping elements for breaking the surface of the ground;
• the frame including a second transverse member having a leveling surface for compressing and levelling the surface of the ground;
• wherein the frame is divided into a plurality of sections arranged in a row across the front and rear transverse members where at least one free section of the plurality of sections is free from the ground scraping elements and the levelling surface;
• wherein said at least one free section comprises two wing sections each on a respective side of a middle section to be used to grade a single traffic wheel strip of the gravel road with the two wing sections arranged to pull material into the middle section.

A drag bar apparatus for attachment to a tractor allowing levelling a surface of ground over which the tractor passes for use with gravel roads having two traffic parallel spaced wheel strips, the tractor having forwardly projecting forks for engaging the drag bar apparatus, the apparatus comprising:

• a frame having a generally planar body for resting on the ground;
• wherein the frame includes a mounting coupling for attachment to a front support of the tractor for movement by the tractor in a levelling action;
• the frame including a first transverse member having downward projecting ground scraping elements for breaking the surface of the ground;
• the frame including a second transverse member having a leveling surface for compressing and levelling the surface of the ground;
• wherein the frame is divided into a plurality of sections arranged in a row across the front and rear transverse members where at least one free section of the plurality of sections is free from the ground scraping elements and the levelling surface;
• wherein said at least one free section is located between two wing sections with the two wing sections used to grade the two traffic wheel strips of the gravel road with the middle section arranged to pull material into at least one of the two wing sections.
