A road drag implement for smoothing gravel roads, comprising:
- (a) a frame having a front end and a rear end,
- (b) a first right side grading blade that is rotatably mounted to the frame for rotation about a upright axis at a pivot location that is located on the right side of the frame, a first blade actuator connecting between the frame and the right side grading blade that is controllable for rotating the blade between a first retracted transport position wherein the right side grading blade is retracted so that the right side grading blade generally does not extend beyond the right side of the frame and a second extended working position wherein the right end of the right side grading blade extends beyond the right side of the frame and forward of and to the right of the pivot location for the first right side grading blade and wherein the left end of the right side grading blade extends behind and to the left of the pivot location for the right side grading blade,
- (c) a second left side grading blade that is rotatably mounted to the frame for rotation about a upright axis at a pivot location that is located on the left side of the frame and spaced behind the pivot location of the first right side grading blade, a second actuator connecting between the frame and the second left side grading blade that is controllable for rotating the second left side grading blade between a first retracted transport position wherein the left side grading blade is retracted so that the left side grading blade generally does not extend beyond the left side of the frame and a second extended working position wherein the left end of the left side grading blade extends beyond the left side of the frame and forward of and to the left of the pivot location for the second left side grading blade and wherein the right end of the second left side grading blade extends behind and to the right of the pivot location for the second left side grading blade and to a location that is behind the left end of the first right side grading blade,
- (d) a wheel assembly including ground engaging wheels, the wheel assembly being pivotably mounted to the rear end of the frame such that the frame may be lowered to a ground engaging position such that the grading blades come in contact with the road surface and such that the frame may be raised into a transport position in which the blades are spaced above the road surface, and,
- (e) a hitch assembly that is mounted to the forward end of the frame and that is adapted to connect with a tractor hitch, the hitch assembly being arranged for changing the elevation of the frame such that the frame may be lowered to a ground engaging position in which the grading blades come in contact with the road surface and such that the frame may be raised into a transport position in which the blades are spaced above the road surface.
