Calculation and Analysis of Grass Removing Angles of Up-cut Rotary Blade

Ding Weimin Peng Songzhi(Nanjing Agricultural University) Wang Yaohua(PLA University of Science and Technology)  
This paper described grass removing angles of the up cut (reverse rotation) rotary blade. It was proved that the grass removing angle equation of up cut rotary blade was the same as that of down cut (forward rotation) rotary blade. Because two kinds of blades work in different angular ranges, they have the different changing laws and magnitudes of grass removing angles. During the tillage stage, the dynamic grass removing angle of up cut rotary blade is greater than that of down cut blade, but grass removing requirement is also a necessary design consideration for up cut rotary blade.
