Abstract

The crop testing and evaluation system includes a plurality of measuring and testing devices that measure the weight, moisture content, and test weight of a crop. Other measuring devices that test the crop for characteristics such as protein content, sugar content, oil content and color may also be included. Mounting accessories are included in the system for attaching the measuring devices to the crop gathering compartment of a harvesting vehicle. As the crop is harvested and fed to the compartment, periodic readings of the measuring devices are taken by a microprocessor and supplied to a computer for analysis and evaluation. Preferably, the microprocessor and computer are positioned in the cab of the harvesting vehicle within reach of the harvest operator.
