PROBLEM TO BE SOLVED: To provide a stirring track apparatus of a fermentative decomposition tank capable of performing stable running due to small drive force by suppressing a tumbling moment at the time of moving and running in a case that a treatment object is thickly deposited in the fermentative decomposition tank. SOLUTION: The stirring track apparatus 1 of the fermentative decomposition tank is constituted of a truck 3 capable of running so as to advance and retreat while straddling the opening part of the fermentative decomposition tank 2 for decomposing discharged substances based on organic matters such as excess sludge in sewage treatment and a stirring means 9 for mixing and stirring the deposit in the fermentative decomposition tank 2 supported under the truck 3. The stirring means is composed of left and right suspended frames 24 suspended from the truck 3, a horizontal axis rotary stirrer 9 for performing rotation and stirring between the left and right suspended frames 24 and longitudinal feed augers 10 perfcorming upward transfer operation at the front and rear positions of the left and right suspended framed 24, and the longitudinal feed augers 10 are arranged in an inclined posture so that the lower end parts thereof are separated from the suspended frames 24 in the advance and retreat direction of the truck.
