In order to improve the work rate of puddling, we developed rotary-type high speed puddling harrows. The stubble burying performance and the soil pulverizing performance of the developed puddling harrows were nearly the same as those of conventional puddling harrows working at 20 to 30% slower travel speeds. Power requirement of the developed puddling harrows were similar to those of conventional harrows. When the developed puddling harrows worked at 24 to 30% higher travel speeds than the conventional harrows, work rates of the developed puddling harrows were 21 to 22% larger, and the fuel consumption of the developed puddling harrows was 13 to 15% less than that of the conventional harrows.
