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. A linear actuator along with side plane adjusters position the brushes to contact the road surface even though the surface is uneven.
