This paper introduces the construction of a testing system for characteristic parameters of working components used for soil and the treatment of key technical problems. A method of picking up data with fixed point and equidistance was described, which uses a computer software to count the displacement pulse signal of the machine set. In this way the position of sampling point is fixed and the tractive force is collected. The experiments prove that the method of picking up data with fixed point and equidistance is not only simple in structure, dynamically displaying data, but also convenient for studying the relationship between parameters of soil firmness and moisture and resistance against tractive force of the machine set.
