Abstract

Based on the results of fundamental studies, we manufactured prototypes of the high-speed rotary tillers. The prototype tiller had the following features. (1) The radius of curvature and the cutting angle of the curved portion of the rotary blade were increased. (2) The lateral mounting intervals of rotary blades were increased. (3) The rear space in the cover was expanded, the rear cover was rollable, and a rake was attached to its tip. (4) Shanks were installed in front of the rotary. Tests on three paddy fields revealed that the developed tiller could work one step faster in forward speed than the conventional tiller. Therefore, work efficiency of the developed tiller was 20 to 30% higher than the conventional tiller and the specific fuel consumption of the developed tiller was 10 to 20% less than the conventional tiller.
