The innovative Dual Dozer, manufactured by HitchDoc, was designed to provide the contractor with superior accuracy and machine adaptability. A patented mount allows the blade to operate independent of the skid steer and holds a grade by receiving a laser signal simultaneously into each laser receiver sensor. The laser controlled grading box is constantly and automatically adjusting on both right and left edges by two hydraulic cylinders, which maintain a precise grade level with a sub-grade accuracy within one eighth of an inch. The Dual Dozer attaches to a tractor 3 point hitch and to most major brand skid steer models. The Dual Dozer is equipped with two blades, which allows forward and reverse grading.
