ABSTRACT:
A road drag for medium and heavy grading projects is provided. The road drag includes a pair of side members and front, center and rear transverse bars that define a rectangular shaped platform. A V-member is disposed adjacent each corner of the platform and steel blades are attached to a first arm of each of the V-members in a downward direction. A center V-member is further attached to the center bar. Steel blades are further attached to ends of the center V-member in a downward direction. A tail board is secured to a pair of extensions that extend from the rear bar of the platform that defines a rear section. The rear section includes means to prevent the tail board from bouncing or hopping during application in order to better distribute material during use. The road drag further includes an axle and preferably dual wheels near or adjacent the tail board. The road drag further includes a front end that extends from the front bar of the platform with attaching means that is hitched to the back of a vehicle. The front end preferably includes a leveling means to raise and lower the platform for transport and work applications.
