DRAWBAR HITCH ADAPTER PROVIDING ROLL AND PITCH FREEDOM |
摘要 |
An adapter for connecting a agricultural implement swivel hitch to a drawing hitch on a towing vehicle that enables relative pitch and roll movement between the implement and vehicle at a single, pinned joint. Elongated openings in a first portion of the hitch adapter receive a transversely aligned connection pin. The openings are sized to allow limited pin angular movement about a vehicular roll axis. A second portion of the hitch adapter is also connected to the connection pin and configured to allow limited relative angular movement about a transverse pitch axis. The connection between the first and second portions at the connector pin allows relative angular movement therebetween about generally co-planar pitch and roll axes. The connector pin is formed from a softer material than the surrounding first and second portions thereby providing an inexpensive and easily replaceable weak link in the hitch adapter assembly.
