Grading Attachment for Skid-Steer Vehicle
First Claim
1. Grading attachment removably affixable relative to a motorized vehicle for distributing and leveling soil, aggregate or other granular materials, the grading attachment comprising:
- a pair of longitudinally spaced apart first and second blade assemblies which extend transversely relative to a longitudinal axis when the grading attachment is in a horizontal grading position, each of the blade assemblies having an outer roughing blade and a longitudinally inboard inner finish blade interconnected by a web member, wherein a lowermost edge of each of the outer roughing blades is spaced significantly below the web member and above a lowermost edge of each of the inner finish blades when the inner finish blades are placed upon a horizontal work surface; and
a mounting fixture affixed to the pair of longitudinally spaced apart first and second blade assemblies for removable attachment to the motorized vehicle.

Abstract
A grading attachment is provided having a longitudinally spaced apart first and second blade attachment assemblies each extending transversely relative to a longitudinal axis and each having an outer roughing blade and a longitudinally inboard finish blade. The finish blades are spaced from one another to define a collection region therebetween. The lower most edge of the outer roughing blades are spaced above the lower most edge of the inner finishing blades when the unit is placed in a horizontal orientation. A mounting fixture is provided enabling the grading attachment to be removably attached to a motorized vehicle.
