4.2.2 Trailer with Ball-Hitch Coupler
A ball hitch coupler connects to a ball that is located on or under the rear
bumper of tow vehicle. See figure 4-2. This system of coupling a trailer
to a tow vehicle is sometimes referred to as “bumper pull.”
The tongue jack is mounted to the A-frame (front, or tongue) part of the
trailer. By rotating the jack handle clockwise, the jack will extend and
raise the tongue of the trailer.

during deceleration automatically synchronizes these trailer brakes with
