A simplified model for cutting mechanism was used in the laboratory to study the torque behavior exhibited in dry sand under the variance of each type of parameter concerned, then formulated this torque behavior in advance, and compared with the equation proposed in theoretic model. From the experimental investigation, the results show that the equation for torque of pushing resistance for sand is slightly different from that proposed in theoretic model.
