An instrumentation system was developed and mounted on an MF 3090 tractor to measure the various performance parameters of the tractor and attached implements. The system was intended to be used for the formation of a database of draft requirements of most of the tillage implements. The system is designed to measure: drawbar pull, three-point linkage forces, rear and front wheel forces, PTO torque, ground speed, tillage depth, fuel consumption, engine speed, and fluid temperatures. Two precision wheel torques and weight transducers three-point linkage-implement force and depth transducer were also developed as part of the tractor data acquisition system. The wheel torque and weight transducers measures the torque and forces acting on the tractor wheels, whereas the other transducer was used to measure the vertical and the horizontal forces on mounted implements of categories II and III. Field tests were conducted with the developed tractor data acquisition system to measure draft of four primary tillage implements on sandy loam soils. The effects of speed and depth on draft of the implements were investigated and a general regression equation to predict draft of the implements was also developed.
