FORD 2009 F-550 v.3 - Manual (Page 266)

Hitch rating
The standard hitch has two ratings depending on mode of operation:
• Weight carrying - requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
• Weight distributing - requires an aftermarket weight distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.

Weight distributing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition on and
all doors closed, allow the vehicle to stand for several minutes so that it
can level.
