An unloading apparatus for a spreader or the like includes a caliper arm mechanism one end of which is secured to the box and the other end of which is secured to a slidable bulkboard. A hydraulic ram spreads the arms of the caliper mechanism to slide the bulkboard rearwardly. A tailgate is mounted for movement in an upward and rearward arcuate path to serve as a shield while material is being thrown from the spreader.
