The coupling mechanism includes a mounting bracket supported on the trailer tongue for pivotal movement along a transverse axis; and a coupling member having a rear and section supported on the bracket for pivotal movement about a longitudinal axis; and a front end section connected to the tractor vehicle for pivotal movement about a vertical axis. A spring loaded linearly adjustable unit pivotally interconnected between the bracket and tongue structure is selectively adjustable to pivotally move the bracket in either direction about the transverse axis therefor concurrently with providing for the application or removal of a load from the tongue structure to vary the distribution of the trailer and tractor loads.
