Development of Torque Measurement Device for Engine Output Shaft on Head-feeding Combine Harvesters

Abstract

A torque-measuring device for an engine drive shaft in head-feeding combine harvesters was developed to collect data for fuel consumption studies and exhaust gas emission tests. This device does not require irreversible alterations on tested combines and is designed to measure torque without any power loss. The margin of error for this device was less than 6% in static torque measurements. The data measured during harvesting operations showed a correlation with that of prior studies. These results indicate that this device will be effective in further studies.
