1. A device for conditioning of earth fields comprising:
- a. A frame having a forward end including hitch means and a rearward end;
b. ground breaking means attached to the forward end of said frame for breaking the surface of the field;
c. ground engaging means including elevating means associated with the forward end of said frame for selectively raising and lower said frame for selectively adjusting the depth of cut of said ground breaking means;
d. leveling and sifting means suspended from said frame behind said ground breaking means for leveling and sifting the broken surface of the field, said leveling and sifting means being a generally planar, rigid, self-sustaining, perforate drag, said drag being suspended in a generally horizontal position in use; and
e. rolling means extending across the rearward end of said frame for compacting the field, said rolling means having a substantially horizontal axis of rotation, said frame pivoting around the axis of rotation of said rolling means.

- 11. A method of leveling, smoothing, and compacting a level dirt playing field comprising a step of attaching to the rear of a powered vehicle a device having ground breaking means for breaking the surface of the field, generally horizontal, rigid, perforate leveling and sifting means for leveling the broken surface of the field, and rolling means for compacting the field, and a step of pulling said device over said field to simultaneously break the surface of the field with the ground breaking means to form furrows and clods, level the broken surface of the field and sift clods with the leveling and sifting means, and compact the field with the rolling means.

13. A device for the conditioning of earth fields comprising:
-
a. a frame having a forward end including hitch means and a rearward end; b. ground engaging means including elevating means associated with the forward end of said frame for raising and lowering said frame; c. toothed scarifier means for forming furrows and clods in the field, said scarifier means being attached to said frame behind the hitch means, and means for selectively raising and holding said scarifier in an upward position relative to its operative position with respect to the frame, the depth of cut of said toothed scarifier being adjustable with the elevating means; d. rotatable pulverizer means for leveling furrows and breaking clods formed by said scarifier means, the height of said pulverizer means being adjustable with the elevating means, including raising the height of said pulverizer means to an inoperative position. e. drag means attached to said frame behind said ground breaking means for leveling the broken surface of the field; and f. rolling means extending across the rearward end of said frame for compacting the field, said rolling means having a substantially horizontal axis of rotation, said frame pivoting around said rolling means.
