Abstract

A method of harvesting a crop material includes gathering the crop material with a harvesting implement as the harvesting implement moves along an initial path through a field. A location and a value of a characteristic of the gathered crop material is sensed at a plurality of intervals. A set of estimated values of the characteristic throughout the field is generated based on the sensed location and characteristic of the crop material at each of interval. A value of the characteristic of the crop material ahead of the harvesting implement is predicted as the harvesting implement moves along a harvest path, based on the set of estimated values of the characteristic of the crop material throughout the field. A function of the harvesting implement may be controlled based on the predicted value of the characteristic ahead of the pick-up.

First claim

The invention claimed is:

1. A harvesting system comprising:
a harvesting implement operable to move along an initial path through a field and having a pick-up for gathering crop material as the harvesting implement moves along the initial path;
a moisture sensor positioned to sense a moisture content of the gathered crop material at each of a plurality of intervals;
a position sensor operable to determine a location on the field of the crop material from which the moisture content was sensed at each respective interval;
a controller disposed in communication with the moisture sensor and the position sensor, wherein the controller includes a processor and a memory having characteristic prediction algorithm stored thereon, wherein the processor is operable to execute the characteristic prediction algorithm to:
receive data from the moisture sensor related to the value of the moisture content of the gathered crop at each interval;
receive data from the position sensor related to the location on the field of the crop material from which the moisture content of the gathered crop was sensed at each respective interval;
generate a set of estimated values of the moisture content of the crop material throughout the field based on the data received from the moisture sensor and the position sensor at each of the plurality of intervals;
predict a value of the moisture content of the crop material ahead of the pick-up of the harvesting implement as the harvesting implement moves along a harvest path based on the set of estimated values of the moisture content of the crop material throughout the field; and
control a rate of application of a crop preservative from a preservative applicator of the harvesting implement based on the predicted value of the moisture content of the crop material ahead of the pick-up.
