Abstract
A hitch head is disclosed as part of a trailer hitch. The hitch head may include an upper surface having an opening for receiving a stem of a hitch ball. A back side of the hitch head may include a pair of ridges for defining an area for receiving an attaching member for attaching the trailer hitch to a towing vehicle. The hitch head may also include a pair of weld recesses between the ridges for defining channels for receiving welds. The ridges and the recesses on the hitch head allow the attaching member to be positioned and welded to the hitch head in a more time efficient manner. The ridges and recess are also configured to reduce the amount of weld material required to weld the attaching member to the hitch head without reducing the strength of the welds.
