A measurement system was installed on the tractor in order to collect field data. PTO and Wheel torques were measured using Telemetry sensing system, and the engine torque was estimated using the sum of each component power.
Telemetry Sensing System
A telemetry sensing system is consisted of wheel and PTO torquemeter. Data from torque meter are transmitted to the DAQ through antennas and amplifiers.
Data Acquisition System
Monitoring system for real-time load measurement was installed inside the tractor. The load data measured in real-time is displayed and saved through the monitoring system.
