An Instrumentation System for Measuring Field Performance of Agricultural Tractors

An instrumentation system is designed to measure the field performance parameters of the most common agricultural tractors and implements. The package is designed such that it can be shifted from one to another easily. Transducers such as load cell, PTa (Power Take Off) torque transducer, magnetic pickups, fuel flow sensor, and PRTs (Platinum Resistance Thermometers) are used to measure drawbar pull, PTa torque and speed, tractor speed and slip, fuel flow, engine speed, and temperatures of fuel and engine. Signals from the transducers are scanned and recorded using a datalogger
