Abstract
A tow point for an asphalt paver, which allows the operator to: (1) select either a fixed or sliding tow point connection; and (2) select from among several possible locations of each, thereby adjusting the distance between the screed and transverse auger of the paver. Combination of these features in a single machine makes it possible to lay down an asphalt mat of uniformly desired thickness, while optimizing use of the aggregate batch particles.
