ABSTRACT:
A wheeled trailer has a frame adapted to be coupled by a drawbar to a towing vehicle. The drawbar has a rear end capable of attachment at any one of a number of vertically spaced points to an anchor member and has an intermediate portion removably retained in an open bottom socket within which is a fulcrum. Vertical adjustment of the rear end of the drawbar effects vertical adjustment of its forward end in a manner to compensate for varying height trailer hitches on different vehicles and enable the trailer bed to occupy a substantially horizontal position. The trailer frame is capable of rocking movement about the axes of its wheels to a position in which the rear end of the trailer bears against the ground.
