Yield mapping for an agricultural harvesting machine

A round baler comprising:

• a bale chamber having one or more bale forming apparatus which form a bale in the bale chamber;
• a size sensor which measures a plurality of dimensions of the bale as the bale increases in size from a partial bale to a completed bale;
• a force sensor which measures a ending weight of the bale upon completion;
• a location determining device which establishes a plurality of locations of the round baler corresponding to the plurality of dimensions of the bale;
• a controller configured to determine a plurality of yields for the bale by correlating changes in the plurality of dimensions of the bale with the ending weight of the bale and generate a map by correlating the plurality of yields with the plurality of locations.

A method of creating a yield map for a round baler comprising:

• forming a bale in a bale chamber;
• measuring a plurality of dimensions of the bale as the bale increases in size from a partial bale to a completed bale;
• determining a plurality of locations of the round baler corresponding to the plurality of dimensions;
• measuring a ending weight of the bale upon completion;
• determining a plurality of yields for the bale by correlating the plurality of dimensions of the bale with the ending weight of the bale;
• and
• generating a map by correlating the plurality of yields with the plurality of locations.
