A dampening device for use with conventional finish dirt scrapers characterized by a shaft with the lower end of the shaft attached to a skid shoe and the upper end of the shaft having a piston mounted thereon which operates in a cylinder, wherein the cylinder has a divider containing an orifice which separates the chamber into a lower chamber and an upper chamber and a by-pass oil line with the upper end opening into the upper cylinder chamber and the lower end opening into the lower cylinder chamber below the piston so that the cylinder operates in a closed oil system in which the oil helps minimize bounce as the piston moves up and down, and a compression-expansion spring surrounding the shaft with the upper end abutting the bottom of the cylinder and the lower end rotatably attached to the skid shoe, the piston and spring working in unison to dampen the normal bounce of the bucket on finish dirt scrapers.
