Such actuators commonly comprise actuators for adjusting the scraper about a longitudinal horizontal axis, about a vertical axis and about a horizontal transverse axis through a hitch connecting a scraper- supporting frame to the vehicle frame. Significant disclosures of actuators for tilting the scraper about a horizontal transverse axis adjacent its immediate support or for adjusting the scraper in the direction of its own longitudinal axis should be cross-referenced to subclass 795.
