<p>PROBLEM TO BE SOLVED: To simplify work for an operator in a working vehicle such as an agricultural tractor. SOLUTION: A tractor has an actuator such as a power shift transmission 12, a hitch 30 and a hitch control system, a PTO and plural selective control valves, to be controlled in response to parameters detected by one or more of control units 44 and an operated controller. A function control system includes a programed control unit 44 having a learning/storing mode opearble when a vehicle moves. One sequence of manual operations for the controller is executed under the learning/storing mode to store information recorded by the control unit 44 together with information as to a distance moved during an operation of the tractor. The control unit 44 has also a regeneration mode operable in response to a command signal, and executes automatically the sequence of the stored operations with a distance interval same to the case where the operations are learnt, irrespective of a vehicle speed.</p> |
