CA 2405133

A surface profiler comprises at least one mass resiliently supported in relation to the frame of the profiler to exert a downward force opposing upward movement of the frame when the wheels pass over an obstacle. Two such masses may be constrained for substantially vertical movement by tie rods extending from pivoting suspension bars secured on distal portions of the frame. A pivoting bracket optionally connects to a handle or to a motor drive unit for propelling the apparatus. The bracket is pivoted about the center point of a line joining the centers of the wheel axles to avoid any torque on the apparatus as a result of operator manipulation.
