The application practice has shown that the tractor can perform the tasks of stubble cleaning,rotary tillage,applying fertilizers,sowing seeds and spraying pesticides in one shot.

It is summarized that the importance to reduce energy consumption of stubble cleaners,to improve abrasion of stubble blades,and to combine farming machine with agric.

This paper attempt to analyze interrelated parametric influence on power dissipation of stubble cleaner,aimed at power dissipation,established mathematical model about the parameter of forward velocity MACHGR 、rotate speed cutter arbor and working width,we have optimized kinematical parameter of soil preparation working,provide considerations for design stubble cleaners.
