The windrow turner, widely used for outdoor fermentation of mushrooms in Europe, has been improved by using rice straw instead of wheat straw in accordance with Korea's actual situation. It was compared with conventional excavator work, and the results were as follows. Agitation performance was $81m^3/hr$, which was 2.8 times higher than $28.6m^3/hr$ of excavator. As a result of the temperature distribution in the pile at the end of the fermentation stage, it was found that the temperature at the lower part of the pile was $5^{\circ}C$ higher than that of conventional pile. This was more favorable for aerobic fermentation. Meanwhile, ash ratio of prototype ($30.9{\pm}1.1%$) was higher than that of control $28.4{\pm}1.6%$. In the case of prototype turner agitation, the yield of mushroom cultivation was $880kg/66m^2$, that was 22.9% higher than the conventional control yield of $716kg/66m^2$.
