Electronic control system for agricultural vehicle

An electronic control system for use by an operator in an agricultural vehicle having a hitch for towing an implement, the control system being operative to control any one or more of a plurality of sub-systems serving to set the vehicle engine speed, the selected transmission ratio, the hitch position to raise and lower the implement, the estimated flow in electro-hydraulic remote lines connectable to actuators of the towed implement, and the engagement state of the power take off shaft, the electronic control system comprising:

• a memory;
• a recording portion operable in a recording mode for storing in the memory a sequence of control steps while such steps are being executed under instruction from the operator, the control system being operable during the recording mode to record a break signal in addition to, and without interruption of, the storing of the sequence of control steps being executed by the operator;
• and
• a playback portion operable in a playback mode for reading a previously recorded sequence of steps from the memory to produce control signals to enable the correct sequence of steps to be executed automatically by the control system, the system being operable to interrupt the automatic execution of the recorded control steps during the playback mode upon detection of a break signal, execution of remaining recorded control steps in the sequence being resumed only in response to an instruction from the operator.
