Abstract
A device for spreading asphalt and other road paving materials is disclosed. The spreader comprises a main body, two separately adjustable wings and various end components to adapt the spreader to different road surfaces, tasks or operator preferences. Structural rigidity and strength results from the use of a three point hitch and a combination of three horizontal, longitudinally position pipes in the main body and three like positioned pipes attached to the wings, said pipes moving coaxially within the main body pipes.
