A method and system for assisting user selection of ballasting options for an agricultural vehicle when coupled to an agricultural implement. The user is presented with a selection menu of implement types, whereby each implement type defines operating ranges of discrete values for first, second and optionally third operational parameters of the vehicle, with the differing combinations defining a values subset. An optimal choice from the available ballasting options is made for each combination in the values subset, and a selection from the optimal choices based on prevalence or probability of occurrence is made and may be presented to the user. Operational parameters may include operating speed, loading due to implement weight and engine power.
