Patent abstract
A device movable across a road to level emulsion thereon. A wheeled frame includes brushes extending downward to engage the emulsion. A manual worm gear connected between the frame and a towbar assembly positions the towbar mount to connect to a vehicle hitch and vertically moves the frame while maintaining the brush contacting plane. Spring biased guide wheels position the brushes to contact the road surface even though the surface is uneven.
