Rear mounted grader for vehicles

Abstract

A rear mounted grader for vehicles comprises a plate member adapted to be vertically secured to the vehicle frame behind the wheels. A pair of rearwardly extending arms are pivotally mounted on the plate member and are provided with a sliding member securely mounted between the arms. A grader blade is transversally disposed relative to the arms and is secured thereunder at the rear end thereof. A hydraulic piston is pivotally secured at one end to the plate member above the pair of arms and to the sliding member at the opposite end for raising and lowering the blade from a position above the ground to an abutting position with the ground, whereby upon actuation of the piston, the blade is adapted to selectively abut against the ground for grading the ground or be lifted therefrom. The grader is preferably provided with spring blades mounted behind the sliding member between the latter and the pair of arms. The sliding member is adapted to abut against the spring blades to allow the blade to resiliently abut the ground when the piston lowers the blade against the ground.
