Abstract
A rear hitch assembly (10) for an agricultural tractor is provided. The assembly comprises a drawbar carrier element (20) mounted to the underside of a chassis (13) by a first connection which permits fore and aft movement of the carrier element relative to the chassis. A second connection includes a load sensor (30) which senses horizontal load placed upon the carrier element. Implement connector elements such as drawbars (22) and connector plates (15) are attached to the carrier in a fixed positional relationship. The horizontal load is isolated from the vertical load and measured by the load sensor to provide load information which can be utilised by brake systems for example.
