Numerous advancements in machinery performance of agricultural tractors have been made in recent years. The Organisation for Economic Co-operation and Development (OECD) tests predetermined points (e.g., maximum power and torque) for drawbar, Power Take-Off (PTO), and hydraulic power as separate tests for tractor performance. Testing methods with the tractor operating at a steady state have been done for years, which were uncharacteristic of agricultural tractor operations in field conditions. As part of this thesis work, field usable data acquisition systems (DAQs) were developed to record implement energy consumption (e.g., drawbar loading, PTO torque, and hydraulic power). The system used LabVIEW software and National Instrument's compact data acquisition systems (cDAQs) to record data from instrumentation measuring drawbar, PTO, and hydraulic loads. Data were collected and verified in accordance with OECD standards at the Nebraska Tractor Test Lab (NTTL), an official OECD testing facility. Requirements of the systems were: implementation of each system on multiple machines with minor alterations, minimal changes to the tractor, and equivalent data compared to that recorded by the NTTL testing devices and procedures. Manufacturer's calibration information along with standardized testing equipment used to tune NTTL testing devices were used to verify that the system would provide data in conformance with OECD testing procedures. The hydraulic system was verified with varying hydraulic line curvatures near the sensors that provided data within a 1 percent difference of the actual hydraulic power. Drawbar tests included calibration of a strain gage instrumented drawbar which recorded loads within 0.67 kN of the calibration fixture. Track testing of the drawbar resulted in measured differences of less than 1 kN with the NTTL load car. For PTO measurements, a power take-off calibration was conducted using a commercially available torque transducer. No statistically significant differences were found between the torque values of the PTO transducer and the dynamometer. The differences in torque values ranged from 3 N∙m to 23 N∙m.

The tractor is a very important piece of machinery in agriculture, and it has been evolving and progressing over the years with improved and increasingly complex functionality. Despite the availability of Organization for Economic Co-operation and Development (OECD) Code 2 tractor testing procedures to evaluate tractor performance, the tests only evaluate individual power outputs from tractors. Additionally, current agricultural machinery management data does not accurately predict the power requirements for various in-field operations. Controller Area Network (CAN) has been incorporated into tractors and other machinery with SAE J1939 and ISO 11783 standards, serving as the communication bus for various on-board electronic controller units (ECUs), and carries various machine operation data that can be used for analyzing machine performance. Investigation of data extraction from CAN messages was conducted by examining the SAE J1939 and ISO 11783 standards. SAE J1939/21 Transport Protocol was also explored to extract engine performance data, which was not found with common filtering methods. A case study on CAN bus data analysis for a combine harvest operation was done to demonstrate the capability of CAN reported data. A Gaussian Mixture Model (GMM) was used for unsupervised learning analysis of the machine load states, and three machine load states were proposed, namely, idle, transport and working states, to characterize machine in-field load states. To analyze tractor operation data that is not available from CAN Bus, Sensor CAN Gateway (SCANGate) was developed for logging data from external sensor instrumentation. SCANGate collected and merged sensor data with CAN Bus and allowed synchronization of CAN reported data and sensor data. Several upgrades to the original SCANGate were done to improve its functionality and durability. A tractor hydraulic instrumentation system was also developed in this study to investigate the in-field tractor hydraulic power usage. Custom orifices were designed and fabricated as a cost-effective solution for hydraulic flow measurement instrumentation. In combination with pressure gauges, hydraulic power usage was computed. Planting operation data collection was used to validate the hydraulic instrumentation system.
