Determining optimal ballasting

A ballasting assistance system for an agricultural vehicle when coupled with an agricultural implement, the system comprising:

• a display device;
• a data storage device;
• and
• a data processing device in communication with the display device and the data storage device, the data processing device configured to select one from a plurality of stored ballasting options for the agricultural vehicle when coupled to a selected agricultural implement, by performing the steps of:
• within a first range of discrete values of a first operational parameter of the vehicle and a first range of discrete values of a second operational parameter of the vehicle, using a received identifier for the selected implement to look up in the data storage device a second range, less than or equal to the first range, of discrete values of the first parameter, and a second range, less than or equal to the first range, of discrete values of the second parameter to obtain a values subset from the combinations of discrete first and second operational parameter values;
• deriving a respective optimal selection from the plurality of ballasting options for each combination in the values subset;
• identifying one ballasting option selection on the basis of a predetermined selection criteria;
• and
• displaying the identified one ballasting option selection on the display device.

A data storage device carrying data defining a software utility, said software utility when loaded to a data processing device in communication with a display device providing a ballasting assistance system for an agricultural vehicle coupled with an agricultural implement in which ballasting assistance system the data processing device is configured to select one from a plurality of stored ballasting options for the agricultural vehicle when coupled to the agricultural implement, by performing the steps of:

• within a first range of discrete values of a first operational parameter of the vehicle and a first range of discrete values of a second operational parameter of the vehicle, using a received identifier for the selected implement to look up in the data storage device a second range, less than or equal to the first range, of discrete values of the first parameter, and a second range, less than or equal to the first range, of discrete values of the second parameter to obtain a values subset from the combinations of discrete first and second operational parameter values;
• deriving a respective optimal selection from the plurality of ballasting options for each combination in the values subset;
• identifying one ballasting option selection on the basis of a predetermined selection criteria;
• and
• displaying the identified one ballasting option selection on the display device.
