A control system including interfaced hand and foot control assemblies for independently conditioning an off-highway implement by selectively positioning a regulator thereof relative a neutral position. The hand and foot control assemblies utilize a common force transfer mechanism in the form of a push/pull cable for moving and positioning the regulator. The foot control assembly includes a self-centered foot pedal and linkages for arranging the push/pull cable relative to the regulator in a manner inhibiting binding forces from being imparted to the cable. The hand control assembly requires independent movement of a control lever in two different planes to shift the hand control assembly from a neutral condition. Moreover, the hand control assembly is isolated from spring forces acting to self center the foot pedal and thus requires low operator efforts to adjust the position of the regulator. The control system of the present invention further includes a mechanism for governing operation of the regulator. A neutral switch assembly is preferably arranged in combination with the hand control assembly for controlling auxiliary functions on the implement.
