ABSTRACT A land plane for leveling or grading the surface of a land area including a frame having front and rear wheel assemblies, a center section and two end sections. A plu- rality of grader blades are supported below the center section which in turn may be raised away from and lowered towards the ground surface by pivoting the end sections of the frame with respect to the center section. Adjustable braces correct warps and distortion in the frame and permit accurate setting of the alignment and angular disposition of the blades with respect to the ground surface. Steering of the plane is controlled through a fluid system which coordi- nates the steering actions of the front and rear wheel assemblies and, alternatively, permits the rear wheel assem- bly to be steered independent of the front wheel assembly.
