Abstract
A tractor-based box blade is used to move and condition soil. The box blade has a plurality of rippers, which are forwardly- and downwardly-extending shanks terminating in relatively narrow teeth that extend into the ground. Each ripper is deployable to extend into the ground independent of the other rippers, and each ripper is stowable away from the ground independent of the other rippers. At least one scraping blade is disposed behind the rippers for smoothing soil.

A box blade comprising:
- a frame having a rear side, a right side extending forwardly from the rear side, and a left side extending forwardly from the rear side;
- a support beam extending between and rigidly affixed to the right side and the left side;
- a scraping blade coupled to a lower edge of the rear side, the scraping blade contactable with the ground;
- a plurality of rippers extendable into the ground when the rippers are in a deployed position, each ripper rotatably affixed to the support beam.
