Abstract
A construction apparatus with a trimmer connected by a three-point suspension wherein each of the three points is independently adjustable for adjusting the angle of the trimmer relative to the main frame in accordance with the desired slope or grade of the ground surface and to raise and lower the trimmer. The trimmer is also provided with an improved carriage for permitting the trimmer to be moved laterally outwardly of the construction apparatus to grade the ground surface alongside the construction apparatus. The construction apparatus preferably molds a paving material onto the ground immediately behind the trimmer so that concurrent grading and molding is accomplished in one pass of the construction apparatus.
