Abstract

A land smoother and packer system for smoothing and packing irregularities in a ground surface. The inventive device includes a frame, a plurality of wheels, a right blade pivotally attached to the frame, a center blade attached to the frame, a left blade pivotally attached to the frame, and a plurality of rollers rotatably attached to the frame behind the blades. The frame has a center portion, a left wing and a right wing that fold upon the center portion for travel. A pair of hydraulic cylinders are attached to the right blade and the left blade for controlling the rotational position of the respective blades. The plurality of rollers are preferably comprised of a center roller, a right roller, a left roller, a right rear roller, and a left rear roller. In operation, the blades are lowered to the desired level for leveling the ground surface of dirt mounds. The rollers follow behind the blades thereby packing the ground surface and forcing any rocks into the ground surface.

Claims

1. A land smoother and packer system, comprising:

a frame;

at least one roller rotatably attached to a rear portion of said frame, wherein said at least one roller includes a solid outer surface;

a plurality of wheels adjustably connected to said frame for adjustably supporting said frame upon a ground surface;

wherein said frame comprises;

a center portion;

a first wing pivotally attached to said center portion; and

a second wing pivotally attached to said center portion opposite of said first wing;

a center blade attached to said center portion of said frame, wherein said center blade extends about a substantial portion of said center portion;

a first blade attached to said first wing, wherein said first blade extends about a substantial portion of said first wing; and

a second blade attached to said second wing, wherein said second blade extends about a substantial portion of said second wing.

2. The land smoother and packer system of claim 1, wherein said first blade and said second blade are pivotally attached to said first wing and said second wing respectively.

3. The land smoother and packer system of claim 2, including:

a first adjustment means mechanically connected between said first wing and said first blade for adjusting and maintaining a rotational position of said first blade; and

a second adjustment means mechanically connected between said second wing and said second blade for adjusting and maintaining a rotational position of said second blade.

4. The land smoother and packer system of claim 1, wherein said at least one roller comprises:

a center roller rotatably attached within said center portion;

a first roller rotatably attached within said first wing; and

a second roller rotatably attached within said second wing.

5. The land smoother and packer system of claim 4, including a third roller rotatably attached to said frame behind and between said center roller and said first roller, and a fourth roller rotatably attached to said frame behind and between said center roller and said second roller.

6. The land smoother and packer system of claim 1, wherein said center blade is V-shaped.

7. The land smoother and packer system of claim 1, wherein said center blade, said first blade and said second blade each have a curved cross sectional area.
