A road-cutting apparatus for creating grooves or impressions in a road surface. The apparatus comprises a tool carrier with a rotatable cutter positioned adjacent thereto. A positioning control arm is hydraulically actuated to place the cutter in an operating position just above the road surface, and an operating control arm is hydraulically actuated to move the cutter into and out of cutting engagement with the road surface. The cutting is automatically carried out in response to a signal generated as a result of the distance traveled along the road surface by the apparatus. The road-cutting apparatus also comprises a transport wheel which can be placed into engagement with the road surface such that the cutter is spaced therefrom for transport of the apparatus to a desired location for cutting the grooves or impressions and raised above the road surface for the cutting operation.
