Tractor-implement performance mapping system.
Published 2004“…The system can measure, display and record in real-time tractor`s theoretical travel speed, actual travel speed, pitch and roll angles fuel consumption rate, drive wheel slippage, drive wheel torque and implement`s PTO torque, plowing depth, drawbar force, and three-point hitch forces. With the added DGPS option, the system can be used for spatial mapping implement field performances. …”

Mapping system for tractor-implement performance
Published 2009“…This complete and integrated system is capable of measuring, displaying and recording in real-time among others, tractor's theoretical travel speed, actual travel speed, fuel consumption rate, rear drive wheel slippage, rear drive wheel torque, pitch and row angles, and also implement's PTO torque, drawbar force, three-point hitch forces, and tillage depth. With the added differential Global Position System (DGPS) option, the system could be used for spatial mapping of the tractor-implement field performances. …”

System Instrumentation and Modeling of Power and Energy Demand for Tillage Operations in Malaysia
Published 2002“…The developed data acquisition system is able to measure and monitor horizontal pull at the tractor drawbar point, torques at both tractor rear drive wheels, torque at the tractor PTO output, and the horizontal and vertical forces on the implement at the 3-point hitch. Static calibration tests on all the designed transducers for the required measurements showed excellent linearity (i.e., correlation coefficients closed to 0.99). …”
