ABSTRACT:
A slope analyzer is provided for attachment to an earth-working vehicle to provide the operator with a direct readout when a selected slope has been attained during the grading operation. An indicator arm is pivotally mounted on a base and movable to a selected slope ratio indicia. Slopes wherein the uphill side of the vehicle is either on the left or the right may be accurately monitored. A curved spring strip forms a preferred retaining means for the arm and a spirit level provides the desired simple readout for the device.
