It can work in twist-waist manner and sway along the sector surface. Simultaneously, one new shrub harvesting method of vertical and horizontal profile modeling for shrub combined manual operation with adaptive profile modeling was proposed. Also experiments on caragana microphylla and sand willow harvest were carried out. The tested results were listed as follows: caragana microphylla missing cutting rate was equal or less than 0.8%, percent of broken stubble was 2.9%；sand willow missing cutting rate was equal or less than 0.8%, percent of broken stubble was 2.5%, the height of stubble was equal or less than 7 cm, reliability coefficient was 98.5%, the turnout was 3 t/h. 
