Abstract
The dump body of a dump truck includes an opening in the bottom of the dump body through which material in the receptacle can be deposited onto an endless conveyor below the dump body. A spreader is removably mounted on the conveyor whereby material moved by the conveyor onto the spreader is discharged rearwardly of the dump truck. The conveyor and spreader unit can be extended and retracted relative to the dump body and can be completely removed from the dump body and the opening in the bottom of the dump body covered when using the dump truck in a dumping mode of operation.
