Earth working scraper apparatus
First Claim
1. A front mounted earth working apparatus for a skid steer, comprising:
- a guide frame portion attached to the skid steer by a mounting mechanism, the guide frame portion having a lifting fork extending forward from said mounting mechanism, and the lifting fork being substantially horizontal with the ground;
a grading portion suspended below said guide frame portion from said lifting fork by a suspension mechanism, said grading portion being substantially parallel with said lifting fork, and said grading portion having a blade attached thereto; and
the suspension mechanism having an attaching mechanism for pulling the grading portion as the skid steer moves forward so that the grading portion will lift without assistance under the lifting fork when the blade hits an unyielding obstruction.

Abstract
A front-end mounted earth working apparatus for a vehicle, including a skid steer, forms the subject of this invention. The earth working apparatus has a guide frame portion and grading portion. The guide frame portion is attached to the skid steer by a mounting plate. The mounting plate has a lifting fork extending forward therefrom being substantially horizontal. The grading portion is suspended below the guide frame portion by the lifting fork using a suspension mechanism. The grading portion being substantially parallel to the lifting fork. The grading portion further having front and rear blades attached to side rails. The rear blades being attached below the side rails by being pivotably hinged at one end and selectively secured to a corresponding adjustment plate so that the angle of each rear blade is adjustable.
