The invention relates to a tractor driving operating test bench, which is characterized by comprising a tractor cab, a signal acquisition unit, a signal processing unit and a virtual reality system, wherein the tractor cab comprises a plurality of cab members, a plurality of sensors and a base; each cab member is assembled on a bottom plate according to the distribution of each operating element in a tractor cab human-computer interface, and is provided with the sensors; each sensor is sequentially connected with the signal acquisition unit, the signal processing unit and the virtual reality system; a virtual tractor model and a virtual scene model are arranged in the virtual reality system; the signal acquisition unit acquires sensor signals on each cab member, and outputs the sensor signals to the signal processing unit through a serial port; and the signal processing unit transmits the calibrated sensor signals to the virtual reality system so as to drive the virtual tractor model to synchronously move. The tractor driving operating test bench can really reproduce the driving operation of a tractor to further develop related ergonomic tests and supplying a gap in national researches in the field, along with relatively higher precision and sensitivity.
