Interpretive Summary:

Technical Abstract: While cotton harvesters have several options for yield monitors; due to the nature of cotton, none of these systems have been able to carry a calibration from one variety to another. This is typically due to the fact that different varieties have different size seeds, and in some instances, especially in stripper harvesting, varying levels of leaf, stick and bur trash during harvesting. The software provides the main interface, and control, between the operator and several auxiliary systems that together comprise an on-board yield monitor calibration system that was implemented onto a basket style cotton stripper. The system was based upon the use of pressure sensors to measure the weight of the basket by monitoring the static pressure in the hydraulic lift cylinder circuit. To ensure accurate weighing, the system automatically lifted the basket to a target lift height, allowed the basket time to settle, then weighed the contents of the basket. The system was field tested under commercial conditions and found to produce an accurate weighing of the load to within 1-2%. As such the system was proven to be capable of providing an on-board auto-correction to a yield monitor for use in multi-variety field trials.
