Abstract
A mechanical hitch control system for a vehicle includes a draft force sensing member, a mechanical hitch control unit, a hitch valve actuator, and a cable transmitting a draft force signal to the hitch control unit. A draft cam is coupled to the draft force sensing and setting members. A position cam is coupled to the position setting member and to a hitch position sensing member. A draft pickup cam is coupled to the draft cam and pivotally mounted on the hitch position setting member. At least one of the cams is operatively engagable with the hitch valve actuator. The cams are enclosed by housing with an opening covered by a removable side plate. The cams and levers are coupled to input members which are inserted through the side plate. The assembled cams, levers and input members are then installed into the housing through the opening.
