The invention discloses an organic compost turner, which consists of a turning part and a walking chassis. The walking chassis includes a chassis frame, a power part, a power transmission device, and a walking wheel. The invention is characterized in that: the turning part, arranged above the walking chassis, includes a motor frame, a major motor arranged on the frame, a transmission mechanism, and two horizontal scraper conveying chain mechanisms arranged symmetrically. The front end of the motor frame is arranged on the chassis frame of the walking chassis. The master motor drives the two horizontal scraper conveying chain mechanisms through the transmission mechanism. Scrapers of the two scraper conveying chain mechanisms move from the external side to the internal side at the front end of the turning part separately.
