摘要: A portable instrumentation system was developed to measure draft and speed when using either pull type or three point hitch mounted implements. The parameters measured were horizontal vertical draft, true ground drive wheel speed. utilized strain gage load cells with excitation provided by a compact, datalogger. Measurements taken stored the dataloger, then transferred via magnetic cassette tape microcomputer for further processing. force dynamometer designed tractors up 80 kW maximum capacity of 60 kN. Calibration procedures, results from use actual tillage energy requirements are presented.
