A simple mechanical height adjustment device adjusts the ground clearance of a trailer. The trailer, having the height adjustment device can selectably and reversibly increase its ground clearance. The trailer, having an adjustable ground clearance, can minimize its load height when operating on improved roads in order to meet local and state height regulation, but can increase its ground clearance on uneven roads.
