The structure and working principle of the self-propelled Salix psammophila stumping machine were described. And aiming at the saw blade rotation speed and walking speed matching problem of the machine, the design and experiment on the working parameters were carried out, such as cutting saw blade linear velocity and machine walking speed, and the structure of the drive chassis. Results of the trial were summarized as follows. The proper linear cutting velocity for Salix psammophila stumping was 50 m/s. And the machine walking speed was determined by the brush size and plants density. The effective uphill angle of the machine walking on sand was less than 10°.
