the tow vehicle brakes. As the trailer pushes against the vehicle, the
actuator telescopes together and applies force to its master cylinder,
supplying hydraulic pressure to the trailer's brakes.
Figure 4-3 – Ball Hitch Coupler With Surge Brake System
We have utilized a coupler that is suitable for the size and weight of the
trailer. The load rating of the coupler and the necessary ball size are
listed on the trailer tongue. You must provide a hitch and ball for your
tow vehicle, where the load rating of the hitch and ball is equal to or
greater than that of your trailer. Also, the ball size must be the same as
the coupler size. If the hitch ball is too small, too large, is underrated, is
loose or is worn, the trailer can come loose from the tow vehicle, and
may cause death or serious injury.
THE TOW VEHICLE, HITCH AND BALL MUST HAVE A
RATED TOWING CAPACITY EQUAL TO OR GREATER THAN
THE TRAILER Gross Vehicle Weight Rating (GVWR).
IT IS ESSENTIAL THAT THE HITCH BALL BE OF THE SAME
SIZE AS THE COUPLER.
The ball size and load rating (capacity) are marked on the ball; hitch
capacity is marked on the hitch.
