A rotary tiller belongs to the technical field of rotary tillers. According to the rotary tiller, the interior of a machine body is provided with a speed-changing direction-changing transmission mechanism, a 360-degree rotating crawler drive mechanism, and a machine speed-reducing box in a cooperative mode. The interior of the machine body is also provided with an engine and a pump body assembly in a cooperative mode, wherein the pump body assembly includes a first variable pump, a second variable pump, and a third variable pump, the third variable pump is in control connection with a machinemotor, and the first variable pump and the second variable pump are connected to left and right crawler-driving motors, respectively. The rotary tiller has a two-stage speed regulation function and ahigh transmission efficiency, and can realize 360-degree rotary reversal in situ; a speed-changing latch handle transmission mechanism has three gear positions, that is, a forward gear position, a neutral gear position and a r
