ABSTRACT:
A scraper apparatus is disclosed for mounting under a body of a truck. The apparatus includes a table having a forward and a trailing end. The forward end is pivotally secured to the body of the truck. The arrangement is such that the table is permitted to pitch relative to the body of the truck. A bearing is secured to the table and is disposed between the forward and the trailing ends. A mold board scraper is disposed below and supported by the table with the mold board scraper being rotatably secured to the table by the bearing. A hydraulic cylinder secured to the mold board scraper rotates the scraper relative to the table and an actuator pivots the table for controlling the pitch of the table and the mold board secured to the table so that scraping of snow, ice and gravel regardless of the level thereof relative to the truck is permitted.
