摘要
A mechatronic-based embedded system was used to measure and display the dynamic wheel axle torque and tractive force of different tractor-implement combinations. It included a special transducer to measure drive wheel torque of a tractor, and an embedded telemetry digital system to receive, process and record the data in SD card module. The observed dynamic wheel axle torque under various tillage operations using different implements were compared with the theoretical values using traction models of Brixius (1987), Wismer and Luth (1973) and Tiwari (2006) to find the model suitable for sandy clay loam soils. The results were compared using the gross traction ratio and motion resistance ratio. Maximum variation of (+) 35% was observed between the developed system and the theoretical calculated values using Brixius (1987) and Wismer and Luth (1973) models, while Tiwari (2006) model had maximum variation of (+)14 per cent.
