In order to produce mushroom compost in low-cost and high-efficiency, a self-propelled turner was developed and compared with the uniformity of compost produced by excavator, compost mixer, and self-propelled turner. The material of the compost was mixed with rice straw and chicken manure at a ratio of 3:1 as dry weight. After the final turning, the internal temperature distribution, the water content of the compost pile, the ash ratio and uniformity of the compost pile were examined. After compost was completed, the water contents were 69.9 ± 0.54, 72.1 ± 0.15 and 74.5 ± 0.82%, respectively. The length of rice straw was 47.5 ± 15.4 cm, 24.9 ± 10.1 cm and 31.0 ± 10.6 cm, respectively. The ash content of the dry weight of each compost were 25.0 ± 6.2%, 33.6 ± 4.2% and 28.2 ± 1.1%, respectively. The deviation of the length of rice straw was affected by the linear velocity of the spinner in the compost mixer and the self-propelled turner, which were 9 m/sec for the self-propelled turner and 21.5 m/sec for the compost mixer. As a result, the mushroom compost was the most uniformly produced by the self-propelled turner.
