The invention relates to a hydraulically controlled crawler-type self-propelled rotary tiller, and relates to the field of agricultural machinery. According to the hydraulically controlled crawler-type self-propelled rotary tiller, the gear pump of a hydraulic system is arranged on the right-upper part of a diesel engine; an oil heat radiator is arranged on a cooling system on the front end of the diesel engine, and is positioned at a middle-upper position of the cooling system; a hydraulic oil tank is arranged on a front-lower position of an operation frame; a hydraulic pump is arranged at the left-back end of a power output transmission box; the power output transmission box is arranged on the back of the diesel engine; a hydraulic motor is arranged on a right-upper part of a travelling gearbox; a hydraulic element is arranged on the right side of the lower-back end of the operation frame; a hydraulic oil fine filter is arranged on a left-side frame of a chassis frame and is close to the hydraulic pump; two hydraulic cylinders are symmetrically arranged on a suspension system. With the hydraulic system, travelling and steering control of the crawler-type self-propelled rotary tiller can be conveniently realized. When problems occur to the hydraulic element, the element can be independently replaced, and the entire hydraulic system does not need replacement.
